To burn any solid fuel efficiently two stages of combustion must be achieved: Primary Combustion and Secondary Combustion (also known as gasification).
• Primary combustion is normal burning as occurs in a traditional open fire. Gasses are released by the solid fuel naturally during primary combustion and in an open fire the chimney draws these un-burnt gasses and a substantial amount of heat straight out into the atmosphere. Open fires therefore result in a very poor combustion efficiency and typically an open fire has an efficiency of 25% or lower. As well as poor combustion efficiency in a traditional open fire other downsides include high fuel consumption, soot deposits collecting in the chimney increasing the risk of chimney fires and the release of harmful smoke emissions to the environment.
• To improve the combustion efficiency enormously secondary combustion or gasification must occur and with our contemporary closed fire and stove systems a number of factors enable gasification to occur:

• 1. Firebox Temperature • The construction of the closed firebox or stove retains the heat from primary combustion very effectively. Depending on the individual appliance this is achieved by the material used (cast iron or high temperature natural firebrick linings) as well as high temperature insulation. Much higher temperatures in the firebox need to be reached (typically over 571 Degrees Celsius) for secondary combustion to occur and this temperature can never be reached in an open fire. At the higher temperature the primary combustion gasses from the solid fuel ignite and secondary combustion occurs.

• 2. Flue Valve • Each manufacturer has their own unique flue valve system and the end result is basically the same. The flue valve is normally controlled automatically and its function is to retain the primary combustion gasses within the firebox until the high temperature is reached. Unlike a traditional open fire the chimney is only fully open when the door of the appliance has been opened for re-fuelling. Yes it is always open to some degree to allow smoke to exit but the flue valve deflects the gasses back into the firebox to be burned.

• 3. Secondary Air Supply • The introduction of a secondary air supply to the firebox is also very important if secondary combustion is to occur. Typically a primary air supply will be delivered to the fire from underneath the fire bed for primary combustion. A secondary air supply is then introduced higher up on the firebox normally, but nor always, through channels around the door.

• It is the combination of the secondary air supply, the high firebox temperature and the primary combustion gasses in the firebox that results in Secondary Combustion or gasification giving very high levels of combustion efficiency.

Altech has been producing various types of stoves since 1983, built of a combination of cast iron and Brasilian soapstone. The traditional types like the Vision, Palladian and Fireview store the heat for 3 to 4 hours.

Gasifying Boilers for Wood

If you have timber freely available why pay for Oil or Gas to heat your home. This boiler will heat your home for less. very easy to use and there is a €2,000 SEI grant available for these units.

CLICK HERE OR MORE INFORMATION>>>>>

The boilers are constructed for burning wood on the principle of generator gasifying with the use of a gas exhaust ventilator, which withdraws the combustion gases from the boiler, or leads air into the boiler.

The boiler body is produced as a weldment of 3-8 mm steel sheets. They comprise the fuel hopper, which is equipped at the bottom with a heatproof pipe fitting with longitudinal hole for the combustion gases and passage of gases. The burnout part of the multiple chamber furnace under the fuel hopper is equipped with ceramic pipe fittings. There is a vertical combustion gas duct in the back of the boiler body, which is equipped with a heating valve in the upper section. The upper part of the combustion gas duct is fitted with a gas exhaust outlet for connection to a chimney.

We also stock a combined boiler for use with pellet and wood

ENVIRONMENT

Reverse combustion and a ceramic combustion chamber enable perfect combustion with minimum polluting emissions. The boilers comply with environmentally-friendly product requirements according to Guideline No. 13/2002 of the Czech Ministry of Environment. They comply the European Standard EN 303-5 and all the boilers rate in class 3

INSTALLATION

ATMOS boilers must be connected via the LADDOMAT 21 or ESBE thermoregulation valve to achieve keeping the minimum temperature of water returning to boiler at 65°C. The temperature of water exiting the boiler must be permanently kept between 80º - 90°C. The default configuration of all boilers includes a cooling circuit to prevent overheating. We recommend installing boilers with accumulation tanks.

CERTIFICATION

All ATMOS boilers are certified in testing laboratories for the individual countries of destination: State Testing Laboratory Brno, TÜV Munich - Germany, Lithuania, Ukraine, Sweden, Poland, Austria, Slovakia, Hungary according to current standards - EN 303-5.

Protected by patent.

Advantages of Wood Gasification Boilers ATMOS:

* Option to burn large pieces of wood
* Primary and secondary air is also preheated to a high temperature -    higher effectiveness
* The ventilator automatically switches off when the fuel but out.
* Ceramic combustion space - high effectiveness
* Large fuel container
* Large space for ash (when burning wood you have to clean it once per    week)
* Boiler without tube plate - easier cleaning
* Small size and low weight
* High quality
