HKRST 20/30/60 boilers burn almost any biomass.
Grain, grain waste, shavings, wood chips, straw, wood pellets etc. up to 30% moisture.
The boiler is constructed as a fire tube boiler with an open bottom grate, insulated with A-batts and covered with aluminum zinc / plastisol steel plates.
The uniqueness of HKRST boilers are compact moving step grates. The step grate means that you can use almost any biomass fuel since the grate movement prevents slag formation.
The boiler can also be fitted with automatic ash removal for easy ash handling.
The boiler can be fitted with hopper directly on the boiler or with stoker and cell lock for bigger hoppers
