Abstract
The invention discloses a hearth device for a biomass furnace. The hearth device for the biomass furnace comprises a furnace body, an induced draft fan and a combustion chamber which is arranged at the bottom of the hearth body, wherein a cover plate is arranged at an upper port of the hearth body, a feed hopper and a smoke outlet are arranged on the cover plate, the smoke outlet is connected with an air inlet of the induced draft fan through a pipe, an air outlet of the induced draft fan is connected with an air inlet formed in a side wall close to the upper port of the hearth body through a pipe, a screen plate is arranged on the side wall of an inner chamber of the hearth body, one end of the screen plate is elastically hinged with the hearth body and the screen plate is arranged above the air inlet. The hearth device for the biomass furnace has the advantages that the high-temperature smoke produced after fuel is combusted can be enabled to enter the hearth again to preheat the fuel to remove moisture, the fuel is enabled to be combusted more fully, the fuel can be prevented from being caked in the combustion chamber and the full combustion is facilitated.
Description
Technical field
The invention belongs to biomass furnace technical field, relate in particular to a kind of firing space device for biomass furnace.
Background technology
Biomass furnace is a kind of Domestic cooking or the heating system developing rapidly in recent years, it has changed the heating mode of traditional stove and accessory taking coal as fuel, make fuel with all flammable biologies such as stalk, straw, in stove, existing naked light burning also has gasification composition, have and there is no tar, not over-emitting black exhaust, thermal efficiency advantages of higher is applicable to rural households and uses very much.But, in long-term use, to find, existing biomass furnace also comes with some shortcomings: 1, when blanking, easily conglomeration in combustion chamber of fuel, causes fuel combustion incomplete; 2, fuel adopts other biomass fuels such as some stalks, straw conventionally, and moisture is larger conventionally, when burning, easily smolders; 3, the high-temperature flue gas producing after fuel combustion is directly discharged into outdoor, and its entrained heat is not effectively used, and causes the waste of the energy.
Summary of the invention
In order to solve existing problem in existing biomass furnace, the object of this invention is to provide a kind of firing space device for biomass furnace.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of firing space device for biomass furnace, comprise burner hearth body, air-introduced machine and be arranged on the combustion chamber of burner hearth body bottom, burner hearth body upper port is provided with cover plate, cover plate is provided with hopper and exhaust opening, exhaust opening is connected with the air inlet of air-introduced machine by pipeline, the air inlet of offering on the nearly upper port place sidewall of the air outlet of air-introduced machine by pipeline and burner hearth body is connected, on the sidewall of described burner hearth chamber body, be provided with web plate, one end of web plate and burner hearth body elastic hinge joint, described web plate is positioned at the top of described air inlet.
Further, described air inlet and exhaust opening place are equipped with backstop.
Further, the circular web plate that described web plate is combined into by the circular web plate of two halves forms, one end of the circular web plate of two halves respectively with burner hearth body elastic hinge joint, the other end contacts with each other.
Further, described web plate is the circular web plate being combined into by the fan-shaped web plate of several and burner hearth body elastic hinge joint.
Owing to adopting technique scheme, the present invention has following superiority:
1, by air-introduced machine, the air inlet on burner hearth body is connected with the exhaust opening on cover plate, so just can make the high-temperature flue gas that generates after fuel combustion again fuel be carried out to preheating to remove moisture entering burner hearth by air-introduced machine, so make that fuel can burn more abundant;
2, by web plate being set in the inner chamber of burner hearth body, in the time of blanking, first fuel drop on web plate, combustion chamber generate high-temperature flue gas and by air-introduced machine be again sent to the intrinsic high-temperature flue gas of burner hearth can to fuel carry out preheating with remove moisture, while making fuel fall into combustion chamber, what burn is more abundant, and, drop on fuel on web plate in the time running up to constant weight, the web plate other end can be pressed down, and then fall into combustion chambers burn, and avoid the conglomeration of fuel in combustion chamber, be conducive to burn.
3, at air inlet and exhaust opening place, backstop is all set, the comburant of larger particles shape or imperfect combustion fuel can be blocked in burner hearth body, avoided contaminated environment on the one hand, be conducive on the other hand it and burn further.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described in detail.
As shown in Figure 1, a kind of firing space device for biomass furnace, comprise burner hearth body 1, air-introduced machine 6 and the combustion chamber 8 that is arranged on burner hearth body bottom, burner hearth body 1 upper port is provided with cover plate 3, cover plate 3 is provided with hopper 4 and exhaust opening 5, exhaust opening 5 is connected with the air inlet 7 of air-introduced machine 6 by pipeline, the exhaust opening 5 of offering on the nearly upper port place sidewall of the air outlet of air-introduced machine by pipeline and burner hearth body is connected, on the sidewall of described burner hearth body 1 inner chamber, be provided with web plate 2, one end of web plate 2 and burner hearth body 1 elastic hinge joint, described web plate is positioned at the top of described air inlet 7.
Described air inlet 7 and exhaust opening 5 places are equipped with backstop, for stopping that particle burning thing escapes into environment, to environment.
As shown in Figure 2, the circular web plate that described web plate 2 is combined into by the circular web plate of two halves forms, one end of the circular web plate of two halves respectively with burner hearth body elastic hinge joint, the other end contacts with each other.
As shown in Figure 3, the structure of described web plate 2 can also be the circular web plate being combined into by the fan-shaped web plate of several and burner hearth body elastic hinge joint.
The present invention is connected the air inlet on burner hearth body by air-introduced machine with the exhaust opening on cover plate, so just can make the high-temperature flue gas that generates after fuel combustion again fuel be carried out to preheating to remove moisture entering burner hearth by air-introduced machine, so make that fuel can burn more abundant; In addition, by web plate being set in the inner chamber of burner hearth body, in the time of blanking, first fuel drop on web plate, combustion chamber generate high-temperature flue gas and by air-introduced machine be again sent to the intrinsic high-temperature flue gas of burner hearth can to fuel carry out preheating with remove moisture, while making fuel fall into combustion chamber, what burn is more abundant, and, drop on fuel on web plate in the time running up to constant weight, the web plate other end can be pressed down, and then fall into combustion chambers burn, avoid the conglomeration of fuel in combustion chamber, be conducive to burn.
