Abstract
The invention discloses a dual-fire-grate biomass hot-blast stove which comprises a heat preservation shell body, a first combustion chamber, a first feeding port connected with the first combustion chamber, a second combustion chamber, a second feeding port connected with the second combustion chamber, an ash deposition chamber below the second combustion chamber and an ash discharge port in the bottom of the ash deposition chamber. The dual-fire-grate biomass hot-blast stove further comprises an air inlet chamber, a fan connected with the air inlet chamber, an air outlet chamber above the air inlet chamber and a hot air outlet in the top of the air outlet chamber. Through the mode, the combustion rate of the dual-fire-grate biomass hot-blast stove can be improved.
Description
Technical field
The present invention relates to hot-blast stove field, particularly relate to a kind of double grate biomass thermal wind furnace.
Background technology
By long production practices, it has been recognized that to only have and utilize raising heat utilization efficiency and the hot working effect that hot blast could be larger as medium and carrier.And common biomass fuel combustion can exist burning insufficient, the low deficiency that waits of burn-off rate.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of double grate biomass thermal wind furnace, can improve the burn-off rate of hot-blast stove.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of double grate biomass thermal wind furnace is provided, comprise: insulation shell, the first combustion chamber, the first charging aperture that connects the first combustion chamber, the second combustion chamber, the second charging aperture that connects the second combustion chamber, the ash accumulating chamber of the second below, combustion chamber, the ash discharging hole of ash accumulating chamber bottom, also comprise inlet air plenum, the blower fan that connects inlet air plenum, inlet air plenum top go out air compartment, go out the hot-blast outlet at air compartment top, it is characterized in that, comprise: the upper grate between the first combustion chamber and the second combustion chamber, lower floor's fire grate between the second combustion chamber and ash accumulating chamber.
In a preferred embodiment of the present invention, described upper grate is vibrating-grate stoker.
In a preferred embodiment of the present invention, respectively there is an air outlet top of described the first combustion chamber and the second combustion chamber.
In a preferred embodiment of the present invention, described inlet air plenum and go out between air compartment to have one deck alumina firebrick, has several air vents on described alumina firebrick.
In a preferred embodiment of the present invention, there is a dust arrester at described hot-blast outlet place.
The invention has the beneficial effects as follows: the present invention adopts double grate design, when the fuel combustion of upper grate is insufficient, enters lower floor's fire grate and burn away, improved the burn-off rate of hot-blast stove.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of double grate biomass thermal of the present invention wind furnace one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, insulation shell, the 2, first combustion chamber, the 3, second combustion chamber, 4, upper grate, 5, lower floor's fire grate, the 6, first charging aperture, 7, the second charging aperture, 8, ash accumulating chamber, 9, ash discharging hole, 10, blower fan, 11, go out air compartment, 12, inlet air plenum, 13, alumina firebrick, 14, hot-blast outlet, 15, dust arrester, 16, air outlet.
