Abstract
The invention provides a double-control type biomass hearth. The double-control type biomass hearth comprises a furnace body, secondary air conveying channels, a lower supporting part and an upper supporting part, wherein the furnace body is a hollow cylinder; a biomass feeding hole is formed in the middle part of the furnace body; the lower supporting part and the upper supporting part both have hollow type conical structures; the area of a top opening of the lower supporting part is smaller than that of a bottom opening of the lower supporting part; the area of a top opening of the upper supporting part is smaller than that of a bottom opening of the upper supporting part; the top of the lower supporting part and the bottom of the upper supporting part are matched and in butt joint, and are integrally molded; and the bottom opening of the lower supporting part is in butt joint with and covers the top opening of the furnace body. With the adoption of the double-control type biomass hearth, the quantity of air entering the hearth can be adjusted through the secondary air conveying channels on two sides, so that biomass fuel in the hearth can be sufficiently combusted; meanwhile, a plurality of vent holes are formed in the lower supporting part at the top of the hearth, and gas which is not completely combusted can be combusted in mixed air, so that the combustion efficiency of biomass is extremely improved and the environment pollution is reduced.
Description
Technical field
The present invention relates to a kind of double-cotrolled type biomass burner hearth.
Background technology
Biomass furnace is a kind of Domestic cooking or heating system that developed rapidly in recent years, it changes the heating mode that conventional oven is fuel with coal, fuel is made with all flammable biologies such as straw, Caulis et Folium Oryzae, in stove, the burning of existing naked light also has gasification ingredient, with or without tar, not over-emitting black exhaust, thermal efficiency advantages of higher, it is especially suitable for rural households and uses.Finding in long-term use, existing biomass stove is typically all at burner hearth bottom air intake and ash discharge, and biomass fuel all can not burn completely, also has combustible gas to be directly discharged in air, cause environmental pollution in the flue gas simultaneously burnt.
Summary of the invention
In order to solve the problems referred to above, the present invention proposes a kind of double-cotrolled type biomass burner hearth, it is possible to be adjusted into the air quantity of burner hearth by the secondary blast road of both sides, it is ensured that the biomass fuel in burner hearth can fully burn；The lower support portion of roof of the furnace is provided with some air vents simultaneously, it is possible to is burnt at this mixing air by the gas of incomplete combustion, greatly improves the efficiency of combustion of biomass, decrease environmental pollution.
The present invention realizes particular by techniques below scheme:
A kind of double-cotrolled type biomass burner hearth, including body of heater, secondary blast road, lower support portion and upper support portion, described body of heater is hollow circular cylinder, it is provided with biomass feed inlet in the middle part of described body of heater, described lower support portion and upper support portion are all the circular cone structure of hollow type, the open top area in described lower support portion is less than bottom opening area, the bottom opening area of described upper support portion is less than open top area, the top in described lower support portion and the bottom of upper support portion coincide and dock and one-body molded, the bottom opening in described lower support portion docks and covers on body of heater top end opening.
Preferably, the biomass feed inlet of described body of heater lateral wall is respectively arranged on the left side and the right side secondary blast road, and the sidewall of the furnace body within described secondary blast road is provided with overfiren air port.
Preferably, described lower support portion is provided with some second-time burning holes run through inside and outside lower support portion.
Preferably, described second-time burning hole is along the inner wall surface tangential direction perforate of body of heater.
What the present invention produced has the beneficial effect that the present invention can maximize the efficiency of combustion of biomass fuel, is more suitable for regulating the size of intake volume simultaneously, meets rural area user demand, decrease environmental pollution.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
A kind of double-cotrolled type biomass burner hearth as shown in Figure 1, including body of heater 1, secondary blast road 2, lower support portion 4 and upper support portion 5, described body of heater 1 is hollow circular cylinder, it is provided with biomass feed inlet in the middle part of described body of heater 1, described lower support portion 4 and upper support portion 5 are all the circular cone structure of hollow type, the open top area in described lower support portion 4 is less than bottom opening area, the bottom opening area of described upper support portion 5 is less than open top area, the top in described lower support portion 4 and the bottom of upper support portion 5 coincide and dock and one-body molded, the bottom opening in described lower support portion 4 docks and covers on body of heater 1 top end opening.
In the present embodiment, the biomass feed inlet of body of heater 1 lateral wall is respectively arranged on the left side and the right side secondary blast road 2, sidewall of the furnace body within described secondary blast road 2 is provided with overfiren air port 3, the air quantity of burner hearth can be adjusted into, it is ensured that the biomass fuel in burner hearth can fully burn by the secondary blast road of both sides；Lower support portion 4 is provided with some second-time burning holes 6 run through inside and outside lower support portion 4 simultaneously, it is possible to is burnt at this mixing air by the gas of incomplete combustion, greatly improves the efficiency of combustion of biomass, decrease environmental pollution.
In the present embodiment, second-time burning hole is along the inner wall surface tangential direction perforate of body of heater, cooling air drives the gaseous fuel in lower support portion 4 to do tangential motion through tangential hole, extend its residence time in cracking room, thus biomass fuel combustion is more abundant, improve efficiency of combustion.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
