Description
Heat accumulating type high temperature preheating burner relates to the combustion system that a kind of burner and storage heater are combined, and is a kind of energy-saving combustion device for industrial furnace.It can be widely used in gas, liquid is on the various industrial furnaces of fuel.
The characteristics of this burner are:
1, burner must be used in pairs, and when a burner combustion, another burner is discharged fume, and the heat storage medium in the storage heater stores the heat in the flue gas, and after the commutation, the stored heat of heat storage medium is used for warm-up combustion-supporting air.
2, can exhaust gas temperature is reduced to about 100 ℃ with air preheat to only being lower than furnace temperature 100-200 ℃, therefore, its heat utilization efficiency be very high.
Succeeded in developing various heat-accumulating burners in succession in the eighties abroad, its principle all is the same, just structurally have nothing in common with each other, and most important be exactly the difference of heat storage medium.The domestic heat-accumulating burner of developing since the late nineteen eighties, it is to be heat storage medium with corrugated heat storage plate that clay matter and cast iron constitute, and has declared patent in 90 years, the patent No. is: 90201755.
This heat-accumulating burner, although on volume with traditional regenerator relatively, dwindle greatly because that its heat storage medium is the size of heat storage plate is bigger, the heat transfer surface area of its unit volume is 260m
2/ m
3, the degree of filling of heat storage medium in regenerator is 0.5m
3/ m
3And used clay matter in the heat storage medium, its accumulation of heat, heat release ability are relatively poor, and the commutation cycle is longer, thereby makes whole heat-accumulating burner volume still seem bigger, and it is restricted in practical application.For making heat-accumulating burner have more practicality, will further dwindle its volume, therefore, need to adopt new heat storage medium and structure.
The utility model is a heat storage medium with ceramic particle high temperature resistant and that have higher accumulation of heat, a heat release ability, is example with the carborundum ball:
Spheroid degree of filling in regenerator is 0.6m
3/ m
3
When sphere diameter was 12mm, the heat transfer surface area of its unit volume was 297m
2/ m
3
When sphere diameter was 10mm, the heat transfer surface area of its unit volume was 356m
2/ m
3
The accumulation of heat of carborundum, heat release speed (thermal diffusivity) are: 0.0147m
2/ h;
The accumulation of heat heat release speed (thermal diffusivity) of clay is: 0.0022m
2/ h.
This shows, adopt new heat storage medium after, the heat transfer surface area of unit volume is increased, degree of filling increases, and accumulation of heat, heat release speed improve, thereby can be at identical combustion air volume, under the situation of identical preheat temperature, further shorten commutating period, further dwindle the regenerator volume.
The concrete structure of utility model is provided by following embodiment and accompanying drawing 1 thereof.
Below in conjunction with profile 1 its detailed structure of explanation and working condition.
The utility model is by regenerator, air, smoke evacuation stop valve, fuel oil, fuel gas shutoff valve, formations such as burning and discharge flue.On its regenerator 5, the lower surface respectively is welded with flange, shell is welded by steel plate, inwall is lined with refractory fibre, the flange Bolt Connection of its underpart flange and air distribution plate 4 and bellows 2, the centre adds the rubber asbestos pad, the blast pipe of bellows 2 connects with air cutoff valve 1, the smoke exhaust pipe of bellows 2 connects with smoke evacuation stop valve 3, heat storage medium 6 is housed in the regenerator, the upper flange of regenerator and burning and discharge flue 10 are used Bolt Connection, the centre adds the rubber asbestos pad, on burning and discharge flue 10 combustion gas or fuel lance 9 is installed, and spray gun 9 connects with combustion gas or fuel-cut valve 8, in the back of burning and discharge flue 10 the accumulation of heat chamber cap 7 of using Bolt Connection is installed, adds the rubber asbestos pad during connection.
Wherein, heat storage medium 6 adopts ceramic particle high temperature resistant and that have higher accumulation of heat, heat release ability, and it can be spheroid, cylinder or Else Rule, erose particle.Pottery can be a corundum, also can adopt carborundum.Adopt the advantage of this graininess heat storage medium:
1, because particle is little, contact with each other between the particle, the thermal expansion amount of particle itself is very little, allows its free wxpansion again, so there is not the problem of thermal stress.
2, because particle is little, periodically variations in temperature is also little for itself, so there is not thermal shock problems.
3, heat storage medium can clean, and cleans easily, can reuse after the cleaning, and therefore, the life-span of heat storage medium is quite long.
4, have the big characteristics of unit volume heat transfer sheet area.
Bellows 2 are welded by sheet metal, and it is used to stored air, and when guaranteeing that air enters air distribution plate on the plate face everywhere pressure even, blast pipe on the bellows 2 and smoke exhaust pipe position can be arranged in side, bottom surface according to field condition.
Fuel oil and gas gun 9; adding high alumina matter porcelain bushing by metallic nozzle and conduit thereof constitutes; because temperature is quite high in the path 10; be the protection nozzle; adopt the outer tube of high alumina matter earthenware as spray wheel 9; pass to a small amount of cooling air between nozzle and outer tube, nozzle adopts heat resisting steel to make, and is welded into one with the ordinary carbon steel conduit.
Burning and discharge flue 10, when burner combustion, the mixed combustion here of the air of preheating and fuel; When burner is discharged fume, play the discharge flue effect.For reducing thermal deformation, its shell adopts cast steel or cast iron manufacturing, and inwall is built the high alumina refractory casting material.Front end is welded with flange and body of heater Bolt Connection, in addition, adds necessary lacing wire again between body of heater steel plate and burner shell, so that burner can connect with body of heater securely.
Accumulation of heat chamber cap 7 is made of steel plate, round steel, refractory fibre, is welded with two round steel handles above the steel plate, is lined with refractory fibre below the steel plate, on regenerator top one opening is arranged, and is used for loading heat storage medium, and the accumulation of heat chamber cap is used for sealing this opening.
The installation of burner and working condition are seen profile 1.
This burner must mounted in pairs and alternation, and two identical heat accumulating type high temperature preheating burners are installed in the both sides of body of heater 11 respectively, and when the burner combustion on the left side, the burner on the right is discharged fume and waste heat recovery.After the commutation, the gas valve 8 and the air valve 1 of left side burner are closed, and its exhaust smoke valve 3 is opened, and this burner plays smoke evacuation and waste heat recovery effect; And the exhaust smoke valve 3 of the right burner is closed, and its gas valve 8 and air valve 1 are opened, and this burner takes fire, and combustion air is by being stored heat preheating within it in heat storage medium 6 processes.Burner comes to this and is periodically moving.
In sum, owing to adopt graininess heat storage medium with higher accumulation of heat, heat release ability, and corresponding structure, further shortened commutating period, therefore, under identical air preheating temperature and waste heat recovery rate situation, compared with prior art, can make the regenerator volume-diminished more than one times, thereby make this heat-accumulating burner have more practicality.
