Features (1) Energy efficient: the biomass hot water boiler half-gasification complete combustion, rapid heating water heater thermal efficiency up to 90% or more; body structure with four backhaul maximum increase heat transfer area, so that the heat can completely conversion; setting a dedicated heat recovery unit, smoke pipe exhaust temperature is below 120 degrees, greatly reducing the burning cost. (2) Environmental: fuel for the comprehensive promotion of environmentally friendly biomass fuel, affordable, wide variety of sources; a special gasification chamber structure enables the fuel fully half gasification combustion, without erecting a tall chimney, just boiler vent connected to the outdoors; integrated dust removal device and configure, emissions visible smoke. (3) Intelligent control: a microcomputer-button operation, can automatically feed automatic ignition with a temperature setting, loop start and stop and fault alarm function, easy operation. (4) Safety and effort: biomass water heater pressure boiler without professional fireman. It can automatically feed automatic ignition 1-2 times-daily feeding, reduce labor intensity (5) Maintenance is simple: the boiler internal vertical smoke tube structure, not easy to coke deposition obstruction has each furnace cleaning the mouth, post-repair and maintenance is simple. Scope Widely used in hotels, guesthouses, sauna bath center, leisure clubs, buildings, apartments, factories, schools and institutions with hot water, bathing and heating. www.pelletburner.org
