Description

The single heat storage type burner

Technical field:

The utility model relates to a kind of industrial furnace and heats special-purpose mixed gas burner, combustion air can be preheated to more than 1000 ℃, is a kind of energy-conservation, consumption reduction, the mixed gas burner that reduces discharging.

Background technology:

The heat storage tank of conventional air single heat storage type burner places in the furnace wall, and air, the easy short circuit of flue gas cause the low and control disorder of heat storage efficiency.The gas pipe of conventional air single heat storage type burner is walked sidepiece, and air, coal gas mix bad, incomplete combustion; Or gas pipe walks the center, and gas pipe places hot environment fully, and the life-span is very short, just needs to change in general 2~3 months.Conventional air single heat storage type burner is not established burner block or is established burner block rather than eddy flow, causes sky, coal gas fully not to mix, and organizes bad flame profile, can not reach completing combustion, can not satisfy the heating process requirement.The utility model " single heat storage type burner " under this background, is innovated efficient, the long-lived air single regenerative formula burner of the innovation a kind of rational in infrastructure of development just.

Summary of the invention:

Goal of the invention: overcome existing air, coal gas mix bad, incomplete combustion, the problem that service life is short provides a kind of efficient, long-lived air single regenerative formula burner rational in infrastructure.

The single heat storage type burner that the utility model relates to is made up of heat storage tank, heat storage, gas-jet tube, whirl burner brick and air swirl passage, and heat storage tank is outer ear suspension type flow dividing structure.Air duct similarly is two " ears ", divides the both sides of driving away.Heat storage tank hangs over the furnace wall outside outward, and it is convenient not in furnace wall, to install, overhaul.This structure stops thoroughly that heat-storing sphere dress is discontented, flue gas is walked short circuit, the furnace wall crack by heat-storing sphere strut, a series of problems such as air preheating temperature is not high, fire box temperature is low, heating efficiency deficiency.The possibility that this structure is not thoroughly collaborated, security is good.Air-flow enters burner block from both sides, walks the center for gas pipe and has created condition.

Heat storage is that diameter is the heat-storing sphere of ∮ 12~20mm, and its material is that high alumina matter, mullite corundum matter etc. are high temperature resistant, high enthalpy amount, high-intensity flame-proof sphere; Its performance requirement is: density is big, thermal conductivity and specific heat capacity height, resistance to elevated temperatures are good, good, the withstand voltage intensity height, low, the anti-oxidant iron etch of linear expansivity, price of drawing of impact resistance is low etc.

The high temperature section part material of center external gas-jet tube is carborundum or high-temperature ceramic, and external low-temperature zone partly is heat resisting steel materials such as 1Cr18Ni9Ti; The center gas pipe is not subjected to high-temperature baking, and long service life generally can reach more than 2 years, and is higher 8~12 times than the life-span of traditional single regenerative burner gas-jet tube.

Air duct separately, the coal gas center that flows away has guaranteed abundant mixing empty, coal gas, even if under the lower situation of gas pressure, empty, coal gas also can fully mix, and reaches completing combustion.

The whirl burner brick is to be made by high temperature resistant refractory material, and has the air swirl passage.Fuel is heated to ignition temperature in this special whirl burner brick, it is easily lighted and burning rapidly, becomes the high temperature dot burning things which may cause a fire disaster, the smooth combustion process, and highly organized flame profile to satisfy the heating process requirement, guarantees that sky, coal gas mix fully, burn.

The air swirl passage makes air become eddy flow, with strengthen sky, coal gas fully mixes.This burner has following functional characteristics and beneficial effect:

1, heat storage tank hangs over the furnace wall outside outward, and it is convenient to install, overhaul.This structure stops thoroughly that heat-storing sphere dress is discontented, flue gas is walked short circuit, the furnace wall crack by heat-storing sphere strut, a series of problems such as air preheating temperature is not high, fire box temperature is low, heating efficiency deficiency.Guaranteed and combustion air can be preheated to more than 1000 ℃, reduced fuel consumption, reduced disposal of pollutants, realized energy-efficient, reduction of discharging.

2, heat storage is that density is big, thermal conductivity and specific heat capacity height, resistance to elevated temperatures are good, the heat-storing sphere of impact resistance good, withstand voltage (drawing) intensity height, low, the anti-oxidant iron etch of linear expansivity, ∮ 12~20mm that price is lower, guaranteed and combustion air can be preheated to more than 1000 ℃, realized energy-efficient, reduction of discharging.

3, external gas-jet tube in center is not subjected to high-temperature baking, and long service life generally can reach more than 2 years, and is higher 8~12 times than the life-span of traditional single regenerative burner gas-jet tube.Realized long-lived requirement.

4, the whirl burner brick has the air swirl passage.It is easily lighted and burning rapidly, become the high temperature dot burning things which may cause a fire disaster, the smooth combustion process, highly organized flame profile to satisfy the heating process requirement, guarantees that sky, coal gas mix fully, burn.Realized requirement efficiently.

5, the air swirl passage makes air become eddy flow, has guaranteed that empty, coal gas fully mixes.

Therefore, the utility model " single heat storage type burner " is new and effective, a long-life type single heat storage type burner of 21 century.
