Specifications of BTK 40-100 kW
This boiler is aimed for manual feed of straw (soya, wheed..) but can be used for wood brickets or coal with declared caloric value greater than 15000 KJ/kg).
Boiler is made by welding steel plates (4-6 mm thickness). Manufacturing process was performed by strict following the guidelines of the corresponding European norms EN 303/5 and ISO 9001. Only certified materials are built in as required by EN 10025, EN 10028-2, EN 10120 and EN 10088-2.
Boiler has capacious upper door to facilitate manual feeding of straw.
Combustion control is done by draught regulator (to be ordered separately and mounted on boiler before use).
Maximum working pressure is 3 bar. Pressure control test is done at 6 bar.
Boiler is delivered with a cleaning kit.
