Advantages of ATMOS coal gasification boilers

• Possibility to burn quality brown coal and wood as a substitute fuel
• Large fuel tank = long burning time
• High efficiency 81 to 88 % depending on the type – primary and secondary air is preheated to a high temperature
• More environmentally friendly combustion – boiler according to EN 303-5:2012 class 4 and 5, EKODESIGN 2015/1189
• Exhaust fan – dust-free ash removal, smoke-free 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 ceramic combustion chamber for ash (for wood collect 1x/week, for coal 1x/day)
• Easy to clean – (C25ST, C32ST, C50S – boilers with tube heat exchanger)
• Small size and low weight
• Choice of door left / right
• 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. The boiler outlet temperature must be constantly maintained in the range of 80 – 90 °C.

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

Boiler regulation

Electromechanical – power regulation is performed by an air control damper controlled by a draft regulator, type FR 124, which automatically according to the set water outlet temperature (80 – 90 °C) opens or closes the air damper. It is necessary to pay increased attention to the setting of the output regulator, because in addition to the output regulation, the regulator performs another important function of securing the boiler against overheating. The boiler is also equipped with a control thermostat located on the boiler panel, which controls the exhaust fan according to the set outlet temperature (80 – 85 °C). 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.

Boiler control panel with standard regulation

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.
