Advantages of ATMOS coal gasification boilers

• Possibility to burn quality brown coal and wood as a substitute fuel
• Large fuel tank – long burning time – up to 12 hours, depending on boiler type
• High efficiency 85,4 to 90,4 % depending on the type – primary and secondary air is preheated to a high temperature
• Ceramic combustion chamber
• More environmentally friendly combustion – boiler according to EN 303-5:2012 class 4 and 5, EKODESIGN 2015/1189
• Exhaust fan – dust-free ash removal, smokeless boiler room
• Cooling loop against overheating – without the risk of damaging the boiler
• Automatic shutdown of the boiler after the fuel burns out – flue gas thermostat
• Convenient ash removal – large space for ash (wood burning – collect 1x/week, – for coal 1x/day)
• Easy to clean – (C25ST, C32ST, C50S – boilers with tube heat exchanger)
• Small size and low weight
• Possibility of choosing a door R / L (right/left) for selected types
• Possibility of connection without accumulation tank
• High Quality

Installation

ATMOS wood gasification boilers must be connected with LADDOMAT 22 or a thermoregulation valve (three-way valve controlled by an actuator in case of using electronic control ATMOS ACD 03) to achieve a minimum return water temperature to the boiler of 65 °C. We keep the outlet temperature of the boiler in the range of 80 – 90 °C and set the temperature of the water to the radiators or floor heating on the mixing three-way valve as needed (e.g. 30 – 80 °C).

All boilers are supplied in a basic design with a cooling loop against overheating. We recommend installing a boiler with accumulation tanks, which will reduce fuel consumption and increase heating comfort.

Boiler regulation

Electromechanical regulation – boiler performance is regulated by an air regulating valve controlled by a draft regulator, FR 124 type, which automatically opens or closes the air valve according to the set water outlet temperature (80 – 90 °C). In addition to performance regulation, the draft regulator helps protect the boiler against overheating. Its advantage is a quick ignition and firing up to the required output when the air valve is fully open. The boilers are equipped with a control thermostat on the instrument panel, which controls the exhaust fan according to the set water outlet temperature (80 – 85 °C) and a flue gas thermostat, which is used to shut down the boiler and turn off the exhaust fan after the fuel has burned out. In the case of connecting a boiler with accumulation tanks, the flue gas thermostat also controls the operation of the pump in the boiler circuit. The temperature on the control thermostat should be 5 °C lower than on the FR 124 draft regulator.

In addition, the boilers are equipped with a flue gas thermostat, which is used to turn off the exhaust fan after the fuel has burned out. The boilers operate at a reduced output of up to 70 % of the rated output even without a fan.

Panel composition:
Main switch, safety thermostat, thermometer, control thermostat and flue gas thermostat

Electromechanical control is the optimal solution for controlling the operation of the boiler (fan) in a simple way.
The design of the panel with standard regulation is the basic design for all manufactured boilers.

Equithermal regulation ACD 03

Each boiler can be equipped with a modern touch electronic control ATMOS ACD 03 for controlling the entire heating system depending on the outdoor temperature, room temperature and time. This regulation is able to control the boiler itself with a fan with many other functions.
