Description
Technical field
The present invention relates to a kind of cyclone furnace combustion system, particularly a kind of cyclone furnace combustion system of recoverable fume afterheat.
Background technology
Current, energy crisis has become the people of the world's problems of concern.Can be fewer and feweri by human use's natural energy resources, but human increasing to the demand of the energy.Simultaneously, problem of environmental pollution has also become the focus that the people of the world pays close attention in recent years.Therefore, the energy-saving and emission-reduction transformation is all being carried out hardy in countries in the world.
Usually, the flue-gas temperature at the furnace outlet place of various boiler plants can reach 700～1000 degrees centigrade.If these high-temperature flue gas directly are discharged in the environment, not only can cause energy waste also can cause to a certain degree destruction to environment.The mode of common recycling fume afterheat is heat exchanger to be set be used for the waste heat of flue gas is replaced to fluid to be heated in flue in the prior art, such as water or air.But, facts have proved that this structure heat exchange efficiency is not high.
In addition, also developed a kind of heat accumulating type structure in the prior art, such as No. 03244707.8 disclosed a kind of low Nox high-efficiency thermal storage industrial furnace of Chinese patent, it comprises body of heater, combustion air preheating/exhaust emission tube road, regenerator and reversing arrangement, it is characterized in that near the furnace wall side a pair of regenerator being set at least at lower portion of furnace body, high-temperature flue gas enters regenerator from the regenerator inboard, the high temperature combustion air enters in the stove from the inboard of another regenerator, and the regenerator outside is combustion air admission passage/smoke evacuation passing away; Fill heat storage in the regenerator, the combustion air pipeline/smoke discharging pipe of regenerator both sides connects exchange system, and the switching by exchange system makes respectively alternately preheated air or the accumulation of heat smoke evacuation of two regenerator.
The hot-blast stoves of the disclosed a kind of air flue two ends heating from hot-blast stove heat storage group of No. 200310123604.7, Chinese patent application and for example, it is comprised of body, heat storage burner, high temperature valve, exchange system, combustion fan, air-introduced machine, chimney, igniter, cold wind hot blast or coal gas air uniform blasting annular flow path and pipeline.A combustion chamber is respectively established at its air flue two ends in hot-blast stove heat storage group, and by the alternation of combustion chamber, two ends, to the heating of hot-blast stove heat storage group, heat storage burner is positioned at both sides or the outside of combustion chamber, two ends, comprises at least two groups.
For another example No. 200510012059.3 disclosed a kind of heat accumulation type metallic magnesium reducing furnaces of Chinese patent application, it is made of burner hearth, furnace roof, stove headwall, burner, reduction tank, furnace bottom, blower fan, it is characterized in that being provided with in the stove headwall internal channel, A group regenerator, B group regenerator, regenerator inside and be full of novel heat storage one ceramic honeycomb body or ceramic bead, stove is provided with chain control valve, transfer valve outward.Two regenerator can replace the switch operating state and reclaim waste heat in the high-temperature flue gas.
Yet, there is following common shortcoming in the disclosed heat accumulating type structure of above-mentioned three patent applications: (1) it need to adopt two cover jet combustion devices with the checker burning direction, and need adopting special switched system switching flue gas and air flow, this is so that the complex structure of body of heater, cost are higher; (2) it needs frequent burning direction, flue gas and the air flow of switching, and this is so that the increasing of control difficulty, efficiency of combustion and operation stability are difficult to obtain effective guarantee; (3) its structure and body of heater that replaces accumulation of heat/preheating combines together so that these structure versatilities low, can not be used for the transformation to existing body of heater.
Therefore, provide a kind of simple in structure and easy to operate alternately regenerative combustion system to become in the industry urgent problem.
