Online InquiryFully welded membrane water wall structure
Large furnace with full membrane sealing structure, more suitable for the combustion of biomass boiler. Lower heat loss, higher thermal efficiency.
Suitable for various of biomass fuels
The corner tube boiler can be applied to various of biomass fuels with high combustion efficiency., especially can solve the impact of the biomass pellet fuel on the heating surface of the boiler when the content of chlorine and sulfur is high, reduce the corrosion and wear of the equipment.
Sufficient combustion space
The drum of the corner tube boiler is external longitudinal arranged or a horizontal arranged, the furnace outlet is arranged at a high position, and the combustion space is relatively sufficient.
Scale-type chain grate
The grate of the corner tube boiler adopts the scale type chain grate. By adding the safety piece, the scale type chain grate will rarely full off its grate piece, and the ventilation evenly.
