Abstract
The utility model provides a circulating combustion furnace in thermal area for supplying heat and burning. The utility model is characterized in that a return-air duct arranged in an exhaust pipe is provided with a return-air hole, and the return-air duct is communicated with an air compartment disposed in a furnace body. Air required by fuel of a combustion chamber for burning is supplied by the return-air duct, when supplying air to air compartment, the return-air duct can bring some flue gas back to burn circularly. The combustion furnace can be used as a coal-fired furnace, a gas-fired furnace and an oil-fired furnace and has the advantages of energy conservation, dust removal and good environmental protection.
Description
The utility model provides the burner in thermal technology field, specifically circulating combustion furnace.
Existing combustion furnace has several basic structures, is typically provided with body of heater and smoke exhaust pipe.In body of heater, establish burning and air supplying chamber.Smoke exhaust pipe communicates with the combustion chamber, and air supplying chamber communicates with atmosphere, or communicates with pressure fan.The flue gas that combustion chambers burn produced directly or by air-introduced machine enters atmosphere.In institute's exhaust body, carbon dioxide gas is arranged, sulfur dioxide gas, the nitrogen oxic gas, overfire air also has not empty full gas and the solid grit that burns.The material that these are imperfect combustion enters atmosphere, not only is unfavorable for environmental protection, nor fuel is made full use of.Wherein overfire air also can be taken away a large amount of available heats.Thereby, also make the combustion heat energy utilization rate low.
The purpose of this utility model provides a kind of sufficient combustion, capacity usage ratio height, the circulating combustion furnace of smoke abatement and dust control.
The scheme that realizes the utility model purpose is, establishes a muffler and be connected with the body of heater plenum chamber in the smoke exhaust pipe of combustion furnace, is provided with return-air hole on muffler.
The combustion furnace that adopts the utility model scheme to make, owing to the required air in combustion chamber is provided by muffler, and muffler is arranged in smoke exhaust pipe, possesses following advantage:
1, muffler is by supplying with the combustion chamber desired gas in the smoke exhaust pipe, and the gas that is positioned at muffler is preheated during by smoke exhaust pipe, thereby, help improving the temperature of combustion chamber, thereby, capacity usage ratio improved.
2, the return-air hole that is provided with on muffler can suck back the combustion chamber with the imperfect combustion flue gas in the smoke exhaust pipe and particle and carry out circulating combustion, and making full use of of favourable fuel realizes energy-conservation effect.
3, owing to institute's smoke discharging part circulating combustion in the combustion chamber, can reduce the pollution level of imperfect combustion material, have the effect of environmental protection atmosphere.
4, be back in the plenum chamber by the soot dust granule in the blast pipe, help the sedimentation of gathering of solid flue dust, help reducing the solid soot emissions of row, also be beneficial to environmental protection to atmosphere.
Elaborate below in conjunction with accompanying drawing
Among Fig. 1,1 is body of heater, is provided with combustion chamber 1a and fire grate 1b and the 1c of air supplying chamber in body of heater 1, in body of heater one side smoke exhaust pipe 2 is installed, and muffler 3 is installed in smoke exhaust pipe 2 is connected with the 1c of air supplying chamber, is provided with several return-air holes 3a on muffler.
The embodiment explanation
With the utility model scheme system coal burning water heating heating stove Fig. 1.
Be welded into water jacket furnace and smoke exhaust pipe and muffler with iron plate.On body of heater or leading flank establish fire door, cylinder iron make grate, be installed in the body of heater, establish ash storage chamber in the plenum chamber bottom.
Behind the fire coal of packing in the body of heater inner combustion chamber; light fire coal; produce flue gas behind the coal combustion; discharge by smoke exhaust pipe; wherein partial fume is mixed into air supplying chamber by the return-air hole of muffler with the air of supplying with from the muffler upper end; supply with the coal combustion required air, the flue gas of backflow carries out circulating combustion with imperfect combustion gas and pellet supply combustion chamber, and the solid grit accumulates in the storeroom.So just, imperfect combustion gas and the solid particle in the smoke exhaust pipe can be burnt again, help energy-conservation, the discharging of depositing dust and the harmful gas of minimizing, the water jacket that especially is provided with on smoke exhaust pipe and the muffler is beneficial to the heat exchange of carrying out flue gas, thereby has improved the heat utilization efficiency of fuel.
The combustion furnace of the utility model structure can also use in large coal-fired boiler and oil-burning gas-fired boiler, reaches the effect of energy-saving and environmental protection.
