Nominal power 30 kW

Hot water boiler KTP 30 for combustion of fire wood, short piece wood, fresh saw dust, wet chips and other wet biomass. Another possible alternative fuel is brown and hard coal. The fuels can be mixed. Boilers comply with Class 3 in accordance with the Norm ČSN EN 303 – 5 EKODESIGN.

Special construction of combustion chamber enabling double combustion, i.e. about 80% gasification and about 20% common burning out.

Boilers are a welded structure, inner plates 5 mm thick, outer walls 4 mm thick. All walls of the boiler body are doubled, filled with water, including the grate made of heat resistant pipes.
