Description
Technical field
The present invention relates to the heating equipment technical field, relate in particular to a kind of boiler of biomass burning shaped fuel.
Background technology
The biomass fuel wide material sources, have that ash content is low, the burning after stain discharges few characteristics, but has calorific capacity low, and the hard defects that moisture content is high, cause the defects such as smooth combustion difficulty.Biomass fuel is through oven dry, machine-shaping; after becoming particle or bulk; its hard defects will disappear fully; the biomass molding fuel wide material sources of this class; belong to regenerative resource; can reach the non-pollutant discharge of " zero-emission " in combustion process, it is low that cost acts as a fuel than electricity consumption and fuel oil, combustion gas, is the New-type fuel that country advocates energetically and promotes at present.
Because biomass molding fuel has the characteristics that volatile matter is high, during burning, flame is long, it is little that traditional packaged boiler is limited by the furnace height deficiency and the furnace cavity that cause on fire grate and structure, just can not this novel fuel of fine adaptation, cause fuel to burn, not skilled worker's shape such as coking, over-emitting black exhaust occurs than being easier to, having wasted fuel has also increased pollutant emission.
And with traditional boiler in bulk, although can accomplish the structure of height, large burner hearth, solved the deficiency of packaged boiler, but the structure heaviness is arranged, consumable material is too much, adds that main heating surface will install at the scene, there will be the installation quality wild effect that is limited by field condition and brings, the field engineering amount is large, the shortcoming that installation period is long.
Summary of the invention
The applicant, for the shortcoming existed in above-mentioned prior art, provides a kind of biological substance for combustion shaped fuel boiler, and it is simple in structure, easy to maintenance, and the fuel combustion utilization is abundant, energy-conserving and environment-protective.
The technical solution adopted in the present invention is as follows:
Biological substance for combustion shaped fuel boiler, comprise grate base, fire grate, and the front end of fire grate is installed the fuel hopper be connected with grate base, and the top that furnace wall is positioned at fire grate is extended with arch wall, and fire grate and arch wall form the first burner hearth; The stove cylinder base is on furnace wall, and stove cylinder and arch wall form the second burner hearth, and the first burner hearth communicates with the second burner hearth, and the stove cylinder communicates with some heat exchanger tubes; In the stove cylinder, level is installed some straight pipes, and the entrance and exit of straight pipe communicates with the second burner hearth and smoke exhaust pipe respectively, and the top of stove cylinder is with exhaust vent, and grate base is positioned at the end of fire grate with slag-drip opening;
