Abstract
The utility model discloses a biomass fuel powder combusting machine, which comprises a furnace body. A combustion chamber is provided inside the furnace body. The inner wall of the combustion chamber is connected with an air supply feeding channel which is tangent to the inner wall surface of the combustion chamber. By adopting the water cooling means, the utility model makes the surface temperature of the combustion chamber no more than 100 DEG and thus prevents hearth damage due to the burning. The ashes are not liable to form slag with high hardness and thus the ash removal is made more convenient. By feeding from the sides, the fuel which is burnt in the furnace inscribed circle is burnt longer and more fully. Thus the combustion efficiency is improved.
Description
Technical field
The utility model relates to a kind of biomass fuel powder combustion apparatus, is specially a kind of combustor.
Background technology
Use the ubiquitous problem of biomass fuel combustion machine that some is arranged at present, the one, the burning built-in temperature is too high, and ashes are easily formed the high rigidity slag in the combustion chamber, influence the deashing operation; The 2nd, combustion furnace generally adopts the mode of positive charging, and the time that fuel is detained in stove is shorter, and it is insufficient to burn, and causes the waste of the energy.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of novel biomass fuel burning machine of power, makes deashing laborsaving, and sufficient combustion is raised the efficiency.
The technical solution adopted in the utility model is as follows:
A kind of biomass fuel burning machine of power comprises body of heater, is provided with the combustion chamber in the body of heater, and the combustion chamber inwall is connected with the air-supply feeding channel, and described air-supply feeding channel and combustion chamber inwall wall are tangent.
Preferably, be provided with the cooling chamber that surrounds the combustion chamber in the body of heater, the indoor cooling fluid that is filled with.
Preferably, described combustion chamber is surrounded by steel plate and forms, and the steel plate outer part is with refractory brick.
Preferably, bottom, described combustion chamber is surrounded to form by steel plate does not wrap refractory brick, is convenient to deashing.
Preferably, refractory brick is located at the end face and the side of outer wall of combustion chamber, and the bottom surface of outer wall of combustion chamber connects the air-supply feeding channel.
The beneficial effects of the utility model are, adopt the mode of water-cooled, make the combustor surface temperature be no more than 100 ℃, and ashes are difficult for forming the high rigidity slag, make things convenient for the deashing operation; Adopt the mode of side charging, fuel makes burning longer more abundant in the burning of stove inscribed circle, makes efficiency of combustion higher.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment combustion furnace.
Fig. 2 is the utility model embodiment combustion furnace side sectional view.
The specific embodiment
The combustion furnace structure comprises body of heater 1 referring to Fig. 1, Fig. 2, is provided with combustion chamber 2 in the body of heater, and section of combustion chamber is circular, is surrounded by steel plate 3, and the area in its outer wall end face and side 2/3 is with refractory brick 4, to increase combustion chamber temperature.The bottom surface, combustion chamber is connected with air-supply feeding channel 5, and described air-supply feeding channel and combustion chamber inwall wall are tangent, and the other end of air-supply feeding channel is communicated with air blast.
Be surrounded by cooling chamber 6 outside the combustion chamber 2, be filled with cooling fluid in the cooling chamber, cooling chamber also is communicated with tank for coolant 7.
Adopt the combustor of such scheme, biomass powder fuel is transported in the combustion chamber by the feeding air-supply passage by air blast during use, because air-supply feeding channel and combustion chamber internal face are tangent, fuel rises along the direction rotation of combustion chamber inwall tangent line and forms the circle of contact under the wind-force effect, be suspended in fully in the air when burning, fully mix with air, burning fully, the carbon monoxide and the dust that have reduced imperfect combustion and produced have improved combustion utilization efficiency.
In addition, combustion furnace adopts the mode of water-cooled, makes steel plate can bear high temperature in the combustor.In combustion chamber bottom and air-supply feeding channel position adopted above-mentioned principle, make its surface temperature be no more than 100 ℃, ashes are difficult for forming the high rigidity slag in the combustion chamber, make things convenient for the deashing operation.
