On Product
•
This boiler is aimed for manual feed of solid fuel (brown coal, firewood, brickets or biomass with
declared caloric value greater than 15000 KJ/kg).
•
Boiler is constructed by welding steel plates (4-6 mm thickness). Manufacturing process was per-
formed 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.
•
Efficiency of the boiler is higher than 77% thanks to its three pass construction.
•
Upper and lower door are covered by refractory insulation material based on VERMICULITE
mineral - large amount of heat is kept in the boiler as a consequence.
•
Boiler has capacious upper door to facilitate manual feeding of the solid fuel.
•
Combustion control is done by draught regulator (to be ordered separately and mounted on boiler
before use).
•
Maximum working pressure is 4 bar. Water control test is done on 6 bar.
•
Boiler is delivered with cleaning kit.
