Description
Technical field
A kind of cracking gas pure oxygen burner is the utility model is related to, it is particularly a kind of to be used in biomass, domestic waste height
Cracking gas part burning pure oxygen burner on warm pyrolysis furnace.
Background technology
Now with a kind of biomass, domestic waste high-temperature cracking furnace, biology is used as using the self-produced cracking gas combustion heat
The thermal source of matter, domestic waste Pintsch process, realize house refuse no pollution processing procedure, biomass as resources complete utilization
Environmental objective.In order to not produce atmosphere pollution dioxin and NOx, in order to improve the calorific value of cracking gas, make it have higher
Use value, biomass, the burner of domestic waste high-temperature cracking furnace, cracking gas burning combustion adjuvant from pure oxygen and do not have to
Air.
The pure oxygen burner used at present is mostly to use natural gas（Composition is mainly methane）And pure oxygen burning.Burnt to protect
Mouth and burner block and because furnace gas is reduced cause Lu Nei localized hyperthermias phenomenon, typically using following from the scaling loss of overheat
Three kinds of methods for reducing flame temperature protection burner.One kind is that water cooling plant is provided with inside burner, but water cooling plant manufacture is not
Height is required nothing more than, and cooling water also takes away substantial amounts of heat；Two kinds are self-cooled pure oxygen combustors, with natural gas and oxygen combustion,
One molecule methane will match somebody with somebody 2 molecule oxygen.It can so design with oxygen stream come cooling burner；Three kinds are that burner band flue gas returns
Stream, exactly with non-combustible furnace gas and oxygen mix come dilution oxygen concentration, so as to reduce ignition temperature.
Cracking gas and pure oxygen burning, the cracking gas of 1 volume match somebody with somebody about 0.5 volume oxygen, 1 volume are about generated after burning
Combustion gas, the combustion gas small volume of generation, the flame temperature of combustion gas is very high, and burner block and burner are difficult to bear this overheat
Scaling loss, do not reach the technological requirement of pyrolysis furnace.
The above-mentioned method that these reduce flame temperature, biomass, the burner of life refuse high temperature pyrolysis furnace can not all use.
First, because biomass, refuse thermal value are relatively low, burner is water-cooled, loses substantial amounts of heat energy, then biomass, the heat of garbage utilization
Can be lower.Moreover water cooling plant is provided with inside burner, manufacture requires high, and the safe operation cycle is short.A second, unit volume
Cracking gas only need the oxygen of about 0.5 unit volume, because amount of oxygen is small, burner can not be allowed to cool；Third, cigarette in recovery furnace
Gas carrys out dilution oxygen, and this method is more infeasible because the flue gas of pyrolysis furnace burner just become after being mixed with cracking gas in stove it is flammable
Gas, combustible gas backflow, which runs into oxygen, to burn, and temperature is higher or even explodes.
Therefore, above-mentioned reduction pure oxygen burner flame temperature, the method for protection burner can not solve cracking gas and pure oxygen burning
When flame temperature it is too high the problem of, burner block and burner are difficult to the scaling loss for bearing this overheat when cracking gas and pure oxygen burning, no
Technological requirement can be met.
The content of the invention
The utility model is innovated for problem present in background technology, there is provided one kind is used for biomass, city
The cracking gas automatic regulating valve on burner and cracking gas passage on life refuse high temperature pyrolysis furnace, it both meets technological requirement,
Scaling loss will not be produced to burner and burner block again.

In cracking gas tube channel, and the valve can make cracking gas tube channel provide the cracking gas more than completely burned needs, form cracking
Gas imperfect combustion.
The cracking gas automatic regulating valve is by the thermocouple temperature sensor and console directly over burner block
The current signal of signal processor outflow drive.Signal processor on thermocouple temperature sensor and console is according to burning
The difference of combustion gas temperature and technique established temperature adjusts the flow of cracking gas in cracking gas tube channel before mouth, is larger than splitting
Vent one's spleen and the cracking tolerance needed for oxygen completely burned, cracking gas part burning, a remaining part is not involved in burning, i.e. part
Burning.Because unburned cracked gas is involved in flame, fuel-rich regions burning is formed, by the brightness and the flame that increase flame
Volume, reduce the temperature of flame.
