Ecomass

The use of biomass boilers has increased as the price of oil and gas

has steadily increased and specifiers become more aware of the need

to consider carbon neutral technologies.

The new Ideal Ecomass range of biomass boilers complements the

market leading range of Ideal boilers. The new range is offered in 13

models with outputs from 100 to 3000kW suitable for floor standing

applications in either single or multiple installations.

Like all Ideal boilers the Ecomass range is offered as standard with

high efficiency and carbon neutral operation that you would expect

from a biomass boiler range.

The burner modulates its operation to ensure that it operates as

efficiently as possible throughout its firing cycle. This ensures that

the boiler is able to match its output to the system requirements no

matter the size.

The full range is built around a solid and reliable steel shell

construction with vertical flueways.

Heat from the burner is drawn through the boiler flueways before

leaving the boiler through the collector hood.

The full range meets and exceeds all current legislation governing

the design, manufacture and safety of heating boilers for commercial

apparatus.

Conforms with all relevant
European standards and
requirements

With the rapid shift evident within the commercial heating market to high efficiency products brought about by changes to Building Regulations it

is inevitable that manufacturers will have to adapt to meet these challenging times. Most of the energy we use is derived from fossil fuels and this

contributes to the depletion of the natural resources we depend upon and increased levels of CO

into the atmosphere.

The introduction of the Ecomass range of biomass boilers is recognition of this fact and demonstrates our commitment to seek alternative fuel

sources for our heating needs.

Performance

Tested and certified to relevant European Standards giving safety

and performance of Commercial and Industrial boilers; the approved

Ideal biomass range offers high efficiency performance.

The efficiency of the range at full load is approximately 93-94%

based on the net calorific value of the fuel.

The Ecomass range is a renewable technology that is defined as

carbon neutral.

The latest refinements ensure high efficiencies at both full and

part load to meet the requests of the latest Building Regulations.

Burner

Wood has been used as a fuel since fire was discovered and as

time has progressed our ability to burn wood both efficiently and

cleanly has improved significantly.

The Ecomass range is the most modern design available and it

can be adapted to burn either wood chip or wood pellet.

The burner technology incorporated within the range produces a

very efficient flame.

Construction

The Ecomass boiler is housed with a stylish silver-grey stove

enamelled sheet steel casing. The heat exchangers are manufactured

from high quality steel.

The combustion chamber is designed to incorporate a three pass

arrangement for optimum heat recovery.

The positioning of the combustion chamber allows for a great

number of gas tubes to be incorporated with insets/turbulators not

only to increase efficiency but also provide automatic clearing of the

flueway tubes.

This cleaning process incorporates a hydraulic system to

periodically move the inserts in the flueway tubes.

Insulation

The Ecomass range is provided with a fully insulated jacket to

maximise heat loss and efficiency.

Installation / Operation

A reception hopper or silo would need to be installed in order to

maintain a supply of fuel. Automatic level detectors can be fitted to

the fuel store to maintain and manage supply of the fuel. A variable

speed server conveyor feeds fuel constantly into the burner where

combustion of the fuel takes place.

Fuel feed and air flow are automatically modulated to meet the

heat demand from the boiler and the system. The boiler will

automatically control between 25% and 100% of the design output.

Fuel

The Ecomass boiler can be supplied to burn either wood pellet

or wood chip*. Each fuel has its own characteristics that would need

to be considered for each specific application in particular the

efficiency of the fuel and the storage requirements.

Wood pellets are a dry clean fuel manufactured from sawdust and

fire wood waste. By compressing the wood it can be formed into pellets.

Specification (Wood Pellet)

Size: 8mm to 15mm diameter

Fires: maximum 10 wt%

Moisture: maximum 12 wt%

Ash: maximum 1 wt%

Whilst wood pellets are preferred material due to the constant

quality and high energy clearly wood chip can be supplied as an

alternative.

Ecomass System Application

Ideal boilers are designed for central heating of commercial and

industrial premises and also for supplying domestic hot water via a

calorifier or plate heat exchanger. They are suitable for fully pumped

or pressurised systems and can be connected to heating and/or

domestic hot water systems.

They are not suitable for direct hot water supply or gravity

heating/hot water systems.

Ecomass 750

Ecomass 3000

Maximum working pressure:

3 bar

Maximum design flow temperature is 82°C (180F)

The return water temperature should be no lower than 60°C. If

it is possible that the return temperature could fall below these

levels then a shut pump must be fitted. Maximum temperature is

30°C.

Quality

As with all Ideal boilers, the Ecomass range is engineered to the

highest quality standards. Ideal Boilers products meet or exceed the

requirements of all relevant standards. Before despatch each boiler

is fired and fully tested. Ideal Boilers are recognised as a World Class

Manufacturer.

Ecomass Range Minimum Water Flow

System design must allow for adequate internal circulation and

sufficient heat release from the boiler body whenever the burner is

firing or during pump overrun. (See flow rate table below for details).

Additionally, the system must be controlled so that part of the load is

available during the pump overrun period to dissipate heat.

Pump Choice: The choice of pump should take into account the

hydraulic resistance given in the table below.

Ecomass Water Treatment

Corrosion will always occur within a heating/hot water system to

a greater or lesser degree irrespective of water characteristics, unless

the initial fill water from the mains is treated. For these reasons Ideal

Boilers Solutions strongly recommends that when necessary the

system be thoroughly cleaned prior to the use of a stable inhibitor

which does not require continual topping up to combat the effects of

hardness, salts and corrosion on the heat exchanger and its

associated systems.

The company advises direct contact with major water treatment

specialists such as BetzDearborn Ltd, Sentinel Division, Foundry

Lane, Widnes, Cheshire WA8 8UD Telephone: 0151 424 5351 or

Fernox, Fry Technology UK, Tandem House, Marlowe Way, Beddington

Farm Road, Croydon CR0 4XS Telephone: 01799 550811.

Ecomass Sealed (Pressurised) Systems

Ecomass 750

Working pressure 3 bar (43psi) maximum.

Ecomass 3000

Working pressure 6 bar (87psi) maximum.

Particular reference should be made to BS 6644: Section 2;

Subsection 11, Guidance note PM5 "Automatically controlled steam

and hot water boilers" published by the Health and Safety Executive

and Water Regulations Guide.

The information and guidance given below is not intended to

override any requirements of either of the above publications or the

requirements of the Local Authority, gas or water undertakings.

In general, commercial closed pressurised systems are provided

with either manual or automatic water make up.

In both instances it will be necessary to fit automatic controls

intended to protect the boiler circulating system and ancillary

equipment by shutting down the boiler plant if a potentially

hazardous situation should arise.

Examples of such situations are low water level and operating

pressure or excessive pressure within the system. Depending on

circumstances, controls will need to be either manual or

automatically reset. In the event of shut down, both visual and

audible alarms may be necessary.

Pressure vessels used must comply with BS 4814 and must

be sized on the basis of the total system volume and initial

charge pressure.

Initial minimum charge pressure should not be less than 0.5 bar

(7.2psi) and must take account of static head and specification of

the pressurising equipment. The maximum water temperatures

permissible at the point of minimum pressure in the system is

specified in Guidance Note PM5.

When make up water is not provided automatically it will be

necessary to fit controls which shut down the plant in the event of

the maximum system pressure approaching to within 0.35 bar (5psi)

of the safety valve setting.

Other British Standards applicable to commercial sealed

systems are:

BS 6880: Part 2

BS 1212

BS 6281: Part 1

BS 6282: Part 1

BS 6283: Part 4

Ecomass Ventilation

BS 6644 - Inputs greater than 70kW (nett)

Open flued application

Safe, efficient, and trouble-free operation of conventionally flued

gas boilers is vitally dependent on the provision of an adequate

supply of fresh air to the room in which the appliance is installed.

Ventilation by grilles communicating directly with the outside air

is required at both high and low levels. The minimum free areas of

these grilles must be according to the scale below. The use of an

extractor fan in the same room as the boiler (or in an adjacent room

in communication) can, in certain conditions, adversely affect the

safe operation of the boiler. Where such a fan is already fitted, or if

an extractor fan is likely to be installed at a later date, then the

advice of the gas supplier should be obtained.

*Required area is cm

per kW of nett input. Note: where a boiler

installation is to operate in summer months (e.g. DHW) additional
ventilation requirements are stated. If operating for more than 50%
of time refer to BS 6644.

Foundation

The boiler must stand on a non-combustible floor (i.e. concrete

or brick). This surface must be flat, level and of a suitable load

bearing capacity to support the weight of the boiler (when filled with

water) and any ancillary equipment. If the boiler is mounted on a

plinth, the dimensions must exceed the plan area of the boiler by at

least 75mm (3") on each side.

Commissioning

All burner units should be commissioned by a fully trained

burner engineer. If required, Ideal Boilers can arrange

commissioning.

Further details and prices are available on request.

Ecomass Installation

For safety, a competent CORGI (Council for the Registration of

Gas Installers) registered installer must fit this appliance. CORGI

requires its members to work to satisfactory standards.

Boiler installation should comply with relevant British Standard

Specifications, Codes of Practice, and current Building Regulations,

together with any special regional requirements of the Local

Authorities, Gas Supplier, and Insurance Company, and in particular:

BS 6891 Low Pressure Installation Pipes, BS 6644 Installation

of Gas Fired Boilers, BS 6880 Part 1-3 Central Heating by Low

Pressure Hot Water, CP 342.2 Centralised Hot Water Supply,

IGE/UP/10 Installation of Gas Appliances in Industrial & Commercial

Premises, Part 1: Flued appliances.

All electrical wiring must comply with lEE Regulations.

Manufacturer's notes must not be taken as overriding statutory

obligations.

Minimum clearances from walls or other fixed objects to allow

for installation, maintenance, and the free access of combustion air

are shown in the boiler clearance diagram.

Flue Systems

Detailed recommendations concerning flue design for gas fired

appliances are contained in BS 6644, and I.G.E. publication UP/10.

These notes are for general guidance only and relevant standards

must be consulted for complete, detailed information.

The chimney and any associated flue connection must have a

cross section area at least equal to that of the smokehood outlet.

Flexible stainless steel liners should not be used for oil fired boilers

in the Pressure Jet range, unless a guarantee of suitability is

obtained from the flue liner manufacturer. The chimney must

generate the minimum smokehood draught requirement given in the

general data table.

Where chimney draught exceeds this requirement, gas fired

boiler installations can be fitted with a draught stabiliser. Care

should be taken when positioning such a stabiliser as its operation

may have side effects, such as burner pulsation, if it is sited where

air turbulence may occur. Installation of draught stabilisers with oil

fired boilers is not recommended because it can cause condensation

and smutting. Ideal Boilers recommends installation of modulating

motorised dampers to provide the most efficient draught control for

oil or gas fired boilers.

Use of a chimney outlet nozzle should be considered if an

increase in gas velocity is required. Discharge velocity should not

exceed 4.9 metres per second (15 feet per second) if used with a

natural draught chimney. If higher discharge velocities are required

use of an induced draught fan should be considered. Care must be

taken to ensure excessive back pressure does not occur when the

boiler fires as this may cause pulsation and lock out of the boiler

control box.

The shortest possible horizontal flue pipe run, connecting the

boiler to the chimney, should be used and bends should be restricted

to a minimum. Sharp 90° bends or tees should not be used.

Whenever possible 90° sweep bends together with 135° bends and

tees should be used.

Chimney termination point should be sited to avoid the risk of

downdraught and should terminate at least 1 metre (3 feet) above

the ridge of the building roof. The possible effect of adjacent

structures upon chimney draught must also be considered. GLC, GCI,

or similar vent terminals are primarily designed for use with natural

draught appliances and are not suitable for boilers in Ideal Boilers

Pressure Jet range.

Exposed chimneys must be adequately insulated to maintain

buoyancy and restrict corrosion. External flue pipes should be well

insulated throughout their length and be designed to offer the

minimum resistance to the flow of flue products. Flue pipe

connections between boiler and chimney must terminate flush with

the inside of the chimney. Existing chimneys should be swept and

brought up to the required standards before the boiler is connected.

Oversize steel chimneys should not be used without a suitably

sized insulated liner of material specification suitable for the flue

being used. Existing brick chimneys should also be lined and

insulated as recommended above.
