Abstract
The utility model discloses a self-preheated heat exchange combustion device and belongs to the field of energy-saving devices. The technical scheme is as follows: a chimney in which an ejector is arranged is connected with an air ejection pipe and a radiant preheater which is provided with a combustion improving air pipe; the same draught fan supplies air for the air ejection pipe and the combustion improving air pipe; a high speed combustor is horizontally fixed below the chimney; an annular seam heat exchanger is arranged at the periphery of the high speed combustor in a surrounding manner and is communicated with the radiant preheater; a sprayer is arranged at the head part of the high speed combustor and fixed with a hearth as a whole; the annular seam heat exchanger is of a multiple concentric pipe type, so that at the time an annular channel of air and smoke is formed, relatively large heat exchange area is provided. The self-preheated heat exchange combustion device has the beneficial effects that the ejection speed of a combustion product is high; the stable combustion scope is wide; the heating time is shortened; the heat exchange efficiency is very high during accelerated heat exchange; an air heat exchanger and the combustor form a whole body, the investment is remarkably saved and the occupied area is reduced; the structure is compact; the assembly is easy; the operation is convenient, safe and reliable and the application scope is wide.
Description
Technical field
A kind of self-preheating type heat exchange burner belongs to energy-saving equipment field.
Background technology
The completing combustion of fuel is the key of saving the energy, and the energy-saving potential of combustion technology aspect is very large.Along with China's energy-saving and emission-reduction state basic policy advances continuing to increase of dynamics, fuel-firing gas-firing replaces fire coal to become the important fuel of each industrial circle and urban heat supplying air feed gradually, and therefore a main energy saving way is exactly to adopt novel burner.Novel fuel gas combustion apparatus one be need to strengthen convection heat transfer' heat-transfer by convection, shortens the heat time; Two will improve temperature uniformity in burner, shorten soaking time.At present, the various burners such as high velocity burner, pulse burner, ultrasonic atomization oil burner, flat-flame burner, swinging burner, heat exchange type burner are all towards this direction effort.With regard to heat exchange type burner, current separate type recuperator burner will have chimney, flue and huge air preheater, invest many, take effect slow, energy-saving effect is poor, it is applied and is restricted.In the urgent need to developing a kind of integral type recuperator burner.
Summary of the invention
The purpose of this utility model is exactly the defect that overcomes existing separate type recuperator burner, and heat exchanger and burner are made of one, and develops a kind of self-preheating type heat exchange burner.
The technical solution of the utility model is: the chimney of in-built injector is connecting injection air hose and radiation pre-heater, radiation pre-heater is equipped with combustion-aid air pipe, injection air hose and combustion-aid air pipe are by same blower fan air feed, under chimney, level is fixed wtih high velocity burner, high velocity burner is outer round circumferential weld heat exchanger, circumferential weld heat exchanger is communicated with radiation pre-heater, and high velocity burner head is equipped with shower nozzle, and is fixed as one with burner hearth; Circumferential weld heat exchanger is multilayer concentric tubular type, in composition air, flue gas circuit, provides larger heat exchange area.
The beneficial effects of the utility model are: the speed of combustion product ejection is high, smooth combustion scope is wide, shorten the heat time, accelerate heat exchanging process, have very high heat exchange efficiency, air heat exchanger becomes as a whole with burner, significantly reduces investment outlay, dwindle floor space, compact conformation, be easy to install, easy to operate, safe and reliable, be widely used.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Describe details of the present utility model and the course of work in detail in conjunction with Fig. 1.The chimney of in-built injector 1 is connecting injection air hose 2 and radiation pre-heater 4, radiation pre-heater 4 is equipped with combustion-aid air pipe 3, injection air hose 2 and combustion-aid air pipe 3 are by same blower fan air feed, under chimney, level is fixed wtih high velocity burner 5, high velocity burner 5 is outer round circumferential weld heat exchanger 6, circumferential weld heat exchanger 6 is communicated with radiation pre-heater 4, and high velocity burner 5 heads are equipped with shower nozzle 7, and is fixed as one with burner hearth 8.Cold wind, tangentially to enter radiation pre-heater 4, carries out preliminary preheating; In circumferential weld heat exchanger 6, utilize subsequently inside and outside two-layer air circumferential weld that flue gas is surrounded, created reasonable heat exchange condition.Circumferential weld heat exchanger 6 is multilayer concentric tubular type, in composition air, flue gas circuit, provides larger heat exchange area, makes circumferential weld heat exchanger 6 have higher heat exchange efficiency.It is heated that air is backflow-type heat exchange by circumferential weld heat exchanger 6 and high-temperature flue gas, from outlet ejection, enters burner hearth 8 with the mist of oil of combustion gas or atomization in the interior mixed combustion of high velocity burner 5.Air after preheating does not almost have radiation loss, is just sent to before the outlet of high velocity burner 5, and with the fierce mixed combustion of mist of oil of combustion gas or atomization, combustion product is to spray at a high speed burner hearth 8 spaces.Under the effect that ejection and injection reflux at a high speed, uniformity and the heat transfer situation of furnace temperature are greatly improved.The interior temperature of burner hearth 8 air preheating temperature in the time of 800～1400 DEG C can reach 300～500 DEG C, can save energy 20%～30% compared with cold wind.The effect of injector 1 is sucking-off flue gas the pressure of controlling burner hearth 8, utilizes the negative pressure causing with the chimney of injector 1 that the flue gas in burner hearth 8 is sucked by the circumferential weld between burner hearth 8 and circumferential weld heat exchanger 6, discharges via chimney.According to the heat capacity of the calorific capacity of combustion gas, fuel oil and requirement, shower nozzle 7 is replaceable, to ensure the spouting velocity of combustion gas or atomization mist of oil.This burner is applicable to natural gas, liquefied petroleum gas, fuel oil or oil-gas mixed burning.The beneficial effects of the utility model are: the speed of combustion product ejection is high, smooth combustion scope is wide, shorten the heat time, accelerate heat exchanging process, have very high heat exchange efficiency, air heat exchanger becomes as a whole with burner, significantly reduces investment outlay, dwindle floor space, compact conformation, be easy to install, easy to operate, safe and reliable, be widely used.
