Technical field
The utility model relates to a kind of secondary oxygen supply shaped fuel combustion furnace, belongs to combustion apparatus field.
Background technology
Current, shaped fuel particularly biomass molding fuel as the main fuel of boiler combustion, because heat energy is high, long, high, the economical and practical environmentally safe of overheavy firing fire box temperature of sufficient combustion, burning time, and being a kind of regenerative resource of clean low-carbon, is the high-quality environment-friendly fuel that substitutes conventional fossil energy.And the abundant burning of shaped fuel, to improve the energy utilization rate, reducing production costs and reducing environmental pollution etc. all has remarkable effect.Existing combustion furnace mainly adopts the mode of oxygen supply burning to carry out, the problem such as have that shaped fuel burning is insufficient, energy utilization rate is low and environmental pollution is serious.Therefore, for making full use of heat energy, the reduction Energy Consumption Cost of the energy and reducing environmental pollution, in the urgent need to developing a kind of novel shaped fuel combustion furnace.
Summary of the invention
Goal of the invention of the present utility model is: by developing a kind of secondary oxygen supply shaped fuel combustion furnace; by twice oxygen supply burning shaped fuel; make shaped fuel burning more abundant, to make full use of shaped fuel heat energy, improve energy utilization rate, reduce production costs and protection of the environment all has positive effect.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A secondary oxygen supply shaped fuel combustion furnace, comprises gallery ports, and described gallery ports are positioned at thermal insulation layer lower end, secondary oxygen supply shaped fuel combustion furnace left side.Described secondary oxygen supply shaped fuel combustion furnace top is a flame export, and described flame export surrounding is evenly distributed with four pot piers.Right side, described secondary oxygen supply shaped fuel combustion furnace top is provided with chimney.Described secondary oxygen supply shaped fuel combustion furnace is a cuboid cavity, and surrounding is thermal insulation layer, and leaching bridge is divided into furnace chamber and ash settling basin, and top is furnace chamber, and bottom is ash settling basin.In described furnace chamber, put shaped fuel.
Described furnace chamber bottom is provided with blower fan, and described blower fan front end is branched into air hose and auxiliary air pipe, and the air that described blower fan is blown into is mainly by air hose, and fraction air enters auxiliary air pipe.The air of described air hose enters furnace chamber bottom, and described auxiliary air pipe enters furnace chamber middle and upper part.Described auxiliary air pipe enters furnace chamber part surrounding and is distributed with auxiliary air spray orifice, and the air in auxiliary air pipe is evenly blown into furnace chamber top, and the derivative of shaped fuel is further burnt, and improves energy utilization rate.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
Secondary oxygen supply shaped fuel combustion furnace of the present utility model, is divided into two parts by the air that enters furnace chamber, makes shaped fuel burning more abundant;
Secondary oxygen supply shaped fuel combustion furnace of the present utility model, can improve and utilize heat energy efficiency, the reduction Energy Consumption Cost of the energy and reduce environmental pollution;
Secondary oxygen supply shaped fuel combustion furnace of the present utility model, provides a kind of combustion furnace of cost-saving synergistic for take biomass molding fuel etc. as the enterprise of fuel.
