Abstract
The utility model provides a double-grate biomass boiler through which biomass fuels inside the boiler can be sufficiently burnt on grates and the energy utilization rate can be guaranteed. The double-grate biomass boiler comprises a hearth, a hopper and grates, wherein the grates are arranged below the hearth, the hopper leads to the grates, the double-grate biomass boiler is characterized in that the grates include a reciprocating grate and a chain grate, the hopper leads to an inlet side of the reciprocating grate, the part from the inlet side to the outlet side of the reciprocating grate is horizontally arranged in a downward inclined manner, the chain grate is horizontally arranged, the outlet side of the reciprocating grate is higher than the chain grate and faces towards one side of the chain grate, the other side of the chain grate extends to the heated surface of a burning cavity at the lower part of the hearth.
Description
Technical field
The utility model relates to the technical field of biomass boiler structure, is specially a kind of biomass double furnace row boiler.
Background technology
If the boiler main Industrial Boiler that living beings are fuel, Industrial Boiler is the important thermal powerplant of China, use wide, demand is large, in recent years, the boiler of biomass fuel is gradually to large scale development, be accompanied by large scale development, the abundant combustion problem of existing biomass fuel boiler is exposed, biomass fuel on existing charging fire grate is positioned at after charging fire grate, due to the route problem of fire grate, when it does not also have abundant burning, enters in ash bucket, biomass fuel cannot fully be burnt, and energy utilization rate is low.
Summary of the invention
For the problems referred to above, the utility model provides a kind of biomass double furnace row boiler, and it makes biomass fuel fully burning on fire grate of boiler internal, has guaranteed energy utilization rate.
A kind of biomass double furnace row boiler, its technical scheme is such: it comprises burner hearth, hopper, fire grate, the below of described burner hearth is provided with described fire grate, described hopper leads to described fire grate, it is characterized in that: described fire grate comprises reciprocal grate, traveling-grate stoker, described hopper leads to the inlet side of described reciprocal grate, the inlet side of described reciprocal grate is to the oblique lower layout of outlet side level, described traveling-grate stoker is horizontally disposed, the outlet side of described reciprocal grate is higher than described traveling-grate stoker, the outlet side of described reciprocal grate is towards a described chain fire-gate side, described chain fire-gate opposite side extends to the heating surface place of the combustion chamber of described lower furnace portion.
It is further characterized in that:
The below of described reciprocal grate is provided with reciprocal grate ash bucket;
Described chain fire-gate below is provided with fire grate ash bucket;
Described hopper is positioned at the face arch position of described burner hearth.
Adopt after the utility model, because biomass fuel is sent into reciprocal grate after-combustion by hopper, after reciprocal grate burning, under the promotion of reciprocal grate face, by the whereabouts of difference in height changeover portion, now fall into after fully mixed traveling-grate stoker, further burning, hot flue gas after burning passes to aqueous medium by heating surface and produces steam or hot water, owing to having adopted reciprocal grate, chain fire-gate double grate structure, the burning of biomass fuel forms length, and biomass fuel then burns after fully mixing again in dropping process, it makes biomass fuel fully burning on fire grate of boiler internal, guaranteed energy utilization rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises burner hearth 1, hopper 2, fire grate, 1 below of burner hearth is provided with fire grate, hopper 2 is positioned at face arch 3 positions of burner hearth 1, fire grate comprises reciprocal grate 4, traveling-grate stoker 5, hopper 2 leads to the inlet side of reciprocal grate 4, the inlet side of reciprocal grate 4 is to the oblique lower layout of outlet side level, traveling-grate stoker 5 is horizontally disposed, the outlet side of reciprocal grate 4 is higher than traveling-grate stoker 5, the outlet side of reciprocal grate 4 is towards a side of traveling-grate stoker 5, and the opposite side of traveling-grate stoker 5 extends to heating surface 6 places of the combustion chamber of burner hearth 1 bottom.The below of reciprocal grate 4 is provided with reciprocal grate ash bucket 7; The below of traveling-grate stoker 5 is provided with fire grate ash bucket 8.
