Abstract
A chain type dual-purpose environment-friendly biomass hot-air and normal-pressure hot-water boiler comprises a boiler body which is in a chain grate and upper drum structure and a boiler furnace which is formed by pouring of refractory materials. A hot air and hot water separating plate is arranged inside an upper drum to divide an upper drum body into a hot air body portion and a hot water body portion, so that the hot air body portion is not communicated with the hot water body portion, the hot water supplies heat to office buildings and workshops, and the hot air supplies heat to hot air required by production. The boiler furnace is divided into a preheating combustion area, a high-temperature radiant combustion area and a residue burnout area through cambered arches. Biomass fuel is subjected to radiant combustion in three areas, and plant caramel tar in the fuel are burnt out completely, so that the plant caramel tar is prevented from blocking a chimney flue safely and effectively, and the problem that plant caramel tar boilers produced by manufacturers in the same industry in China can not operate stably in one to two heating periods or even one to two months is solved; the boiler can be used for achieving two purposes and is convenient to use, capable of reducing the investment cost and high in applicability.
Description
Technical field
The present invention relates to boiler, particularly chain-type biomass hot air atmospheric hot-water boiler for dual purpose.
Background technology
At present, non-renewable energy resources resource worsening shortages, threaten mankind's harmony to develop healthily, home and abroad is all in development energetically and the extensive utilization promoting the renewable sources of energy, the low-carbon emission energy-saving and emission-reduction such as solar energy, wind energy, biomass energy, reduce the clean reproducible energy of sulfur dioxide to the severe contamination that air causes and are widely used.China is abundanter as the resource such as agricultural crop straw, peanut shell, rice husk, sawdust, shrub of biomass energy.Only repressedly be processed into the fuel that biological particles just can be used as boiler, but plant sugar diluted tar can not after-flame completely in application in the past, general biomass boiler is at one or two Heating Period, and even one or two months, the chimney air flue of plant sugar diluted tar blocking boiler, the operation that boiler safety is stable can not be made, for the difference of China region with some industry, both high-temperature hot-air had been needed to produce, atmospheric hot-water is needed again to heat, prior art can only be independent hot air boiler and hot-water boiler, two overlap independently heating equipment, result is energy waste, floor space is large, equipment investment is large, personnel drop into many.
Summary of the invention
The technical problem to be solved in the present invention, being to provide a kind of employing biological particles is fuel, can plant sugar diluted tar in burnt-up fuel, ensure that the not stifled chimney air flue of plant sugar diluted tar makes boiler safety stable operation safely and effectively, the dual-purpose environment-protection boiler of chain-type biomass hot air atmospheric hot-water of hot blast and hot water can be provided.
