Wood and Coal Gasification Boilers

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

The boiler body is produced as a weldment of 3-8 mm steel sheets. The boiler consists of two chambers, one placed upon the other. The upper chamber makes up the fuel container, and the lower one, combustion chamber and ash collector. Between the two chambers, a new, rotating, patent protected grate is placed. The grate ensures perfect combustion of coal, wood, or a combination thereof, as well as simple cleaning.

Advantages of Wood and Coal Gasification Boilers

The secondary air supply channel and the flat part of gasifying grate must always point downwards.

Black coal boilers ATMOS AC25S

The boilers are constructed to burn NUT 1 black coal and wood. On a base of gasification process with a suction fan (S) to suck waste gasses into the chimney.

The boiler body is produced as a weldment of 3-8 mm steel sheets. The boiler consists of two chambers, one placed upon the other. The upper chamber makes up the fuel container, and the lower one, combustion chamber and ash collector. Between the two chambers, a new, rotating, patent protected grate is placed. The grate ensures perfect combustion of coal, wood, or a combination thereof, as well as simple cleaning. The primary and secondary air are pre-heated to a very high temperature for achieveing high efficiency and good quality burning.

The recommneded fuel is NUT 1 black coal. As domestic fuel, logs of wood (length 330mm), brown and black coal of a larger size (NUB), or brown-coal and wooden briquettes can be used.

Advantages of Black coal boilers ATMOS AC25S:

• Burning coal and wood separately, we recommend together
• Large fuel container
• Simple handling and cleaning
• Coolining loop protecting the boiler against overheating
• Revolving furnace grate - easy for ash removal
• The boiler contains no tubing - simple cleaning
• The secondary air is pre-heated to high temperatures
• Small size and low weight
• Fan controlled - pressure(S)
• Automatic switching off the boiler after burning down

Boiler Regulation

Electrical - mechanical - Power is controlled with a safety valve operated with the draught regulator, FR 124 type, which automatically opens or closes the safety valve according to a set output temperature of water (80 - 90°C). When setting the power regulator, much attention should be paid because the regulator has another important function other than power regulation - it also secures the boiler against overheating. A controlling thermostat located on the boiler panel regulates the fan according to a set temperature (80 - 85°C). A temperature lower by 5°C should be set on the controlling thermostat rather than on the FR 124 draught regulator. Boilers contain waste gas thermostat which serves to stop the suction fan when the boiler burns down. The boilers work for 70% without the fan on.

Each boiler can be fitted with ATMOS ACD 01 equithermal controller. It takes a control of the heating system based on datas collected from external sensors and on time. It can control suction fan of the boiler as well.
