Advantages of ATMOS coal gasification boilers:

• possibility to efficiently burn brown coal and wood as alternative fuel
• large fuel storage = long burning time
• high efficiency 81 – 88 % depending on the model – primary and secondary air is preheated to a high temperature
• eco-friendly combustion – boiler according to CSN EN 303-5 class 5, Ecodesign 2015/1189
• exhaust fan – dust-free ash removal, smoke-free boiler room
• cooling loop against overheating – no risk of boiler damage
• automatic boiler shutdown after fuel burn-out – flue gas thermostat
• convenient ash removal – large ceramic combustion space for ash (coal is removed once a day, wood once a week)
• boiler without a tube – easier cleaning
• small dimensions and low weight
• high quality
