Description
Technical field
The invention belongs to workpiece heat and heat treatment field of combustion technology, more particularly to a kind of single regenerative burner device.Especially
It is related to a kind of outer ear suspension type, multithread stock, spiral-flow type single regenerative burner device.
Background technology
Regenerative combustion technology is an energy-saving and environmental protection new technology for effect is significant, is at home and abroad generally pushed away in recent years
Wide application.
From current each application example, the first application mode with the built-in recuperative heater in tunnel be main
Represent.This technology is integrated with heating furnace by burner, built-in heat-storing sphere, by the way of centralized dispersal reversing.It is characterized in knot
Structure is relatively easy, and valve quantity is few.Seen according to relevant information introduction and production practices, this kind of mode has certain defect：(1) collect
Middle commutation makes space gas and furnace pressure fluctuation big, automatically controls realization difficult；(2) pipeline between reversal valve and burner spout
Interior remaining coal gas amount is relatively more (part information introduction reaches the 3% of heat consumption), and this part coal gas is directly discharged by air-introduced machine；
(3) mode of the built-in heat storage of furnace wall requires to thicken furnace wall (more than 1 meter), at the same it is high to the requirement of furnace wall materials for wall, especially
Cracking resistance, causes cleaning lime-ash difficult after (4) built-in heat-storing sphere；(5) mode of centralized supply wind and coal gas is unfavorable for that each sprays
, there is Biased flow phenomenon in the uniform flow distribution of mouth.Due to above mentioned problem, current newly-built recuperative heater typically no longer builds built-in
The heating furnace of formula structure.
According to the actually used situation of heat storage type combustion, a kind of modified accumulation of heat applied on heating furnace is developed again and is fired
Burning technology, i.e. heat-accumulating burner technology.This technology is external by heat storage and independently forms a burner, in control mode
Equally it has been divided into centralized Control and two kinds of forms of decentralised control.Postponed outside heat storage and bring structure flexible arrangement, Maintenance and Repair
The advantages of facilitating, while the thickness of furnace wall need not be increased, it is essentially identical with traditional furnace wall structure, it is suitable for old furnace modification and place
The nervous situation of arrangement space.
In second regenerative combustion technology, current heat storage mainly has two kinds in the form of, and one kind is heat-storing sphere,
Another kind is honeycomb ceramics.Comparatively speaking, the specific surface area of honeycomb ceramics is more much bigger than heat-storing sphere (about 5 times), therefore heat exchange efficiency
It is higher.But its desired commutating frequency is higher, about 30 seconds~60 seconds, valve is cut soon for heat storage material and reversing arrangement, coal gas
Requirement it is higher.And heat-storing sphere changes convenient, can recycle.
The content of the invention

Preheating temperature is not high, the problem of gas pipe short life and heating efficiency deficiency etc..
A kind of single regenerative burner device, including heat storage tank 1, heat storage 2, coal gas burner 3 and burner block 4.Heat storage tank 1 is built-in
There is heat storage 2, for accumulation of heat, coal gas burner 3 is embedded between the ear formula air duct of heat storage tank 1, burner block 4 stores with outer ear suspension type
The passage of hot tank 1 is connected.
Furnace wall outside is hung over outside heat storage tank 1, is ear formula external hanging type structure, two ear formula air ducts separately walk both sides, gas
Stream flows in exchange mode up and down, and combustion air is preheated to 900~1000 DEG C.The shell of heat storage tank 1 is made up of shaped steel and steel plate, interior
Lining castable refractory and refractory fibre, to ensure the service life and heat insulation effect of heat storage tank 1.
Heat storage 2 be nodular fire material, material be cordierite, High-Alumina or mullite high-temperature refractory, directly
Footpath is 10~20mm, high temperature, high intensity, high enthalpy amount, and with enough heat storage capacities.
The high temperature section material that coal gas burner 3 is contacted with burner block 4 is carborundum tube, and low-temperature zone is austenite stainless steel
Matter, austenitic stainless steel is Cr25Ni20Si2 or 1Cr18Ni9Ti etc..Coal gas burner 3 is combined type gas-jet tube structure, typically
Can be used more than 2 years, it is higher than the life-span of traditional single regenerative burner gas-jet tube 8~12 times.
Coal gas burner 3 is external gas-jet tube structure, it is to avoid coal gas burner is in hot environment, is not dried by high temperature
It is roasting, it is ensured that air gas is not collaborated mutually, more security；The long service life of coal gas burner 3, installs, overhauls convenient；Coal gas burns
Mouth 3 makes coal gas flow away center in the center of burner arrangement, it is ensured that air gas is in the fully mixed of the exit of coal gas burner 3
Close, even in the case where gas pressure is relatively low, air gas can also be sufficiently mixed, and reach and burn completely.
The material of burner block 4 be High-Alumina and mullite high-temperature refractory in one or two, temperature in use is
1200~1600 DEG C；Burner block 4 is provided with air multithread stock, swirl channel, when being mainly used in air by burner block 4, is formed very
The stream stock of many eddy flows is fully merged with coal gas, reaches the purpose burnt completely.
The advantage of the invention is that：Outside furnace wall, air-flow flows outer ear suspension type heat storage tank in exchange mode up and down, pacifies
Dress, maintenance are convenient.The structure thoroughly prevent flue gas walk short circuit, air preheating temperature is not high, fire box temperature is low, heating efficiency is not enough
A series of problems, such as.Ensure that can be preheated to 900~1000 DEG C by combustion air, reduce fuel consumption, reduce disposal of pollutants, real
Efficient energy-saving and emission-reducing is showed.
