At present, the general fireproof tempering device by installing between combustion system and gas pipeline, its form is to stop tempering, as pipe laying spark arrester, being provided with filter core in spark arrester inside is main, but it is high to there is operating cost, and due to the impurity contained in coal gas more, very easily cause filter core to block, and then affect the even running of combustion system, need the deficiency of often cleaning or more renew cartridge for this reason; Also to have and adopt hydrolock, namely liquid barrier tempering built-in in device is utilized, as " application of tempering water seal arrangement in combustion system " Research Literature, then entered in tempering water seal arrangement through gas inlet pipe by the Gas Flow with certain pressure, and accumulate in gas inlet pipe; After the pressure in gas inlet pipe reaches certain value, coal gas can be broken through bottom gas inlet pipe to the fluid-tight between the main body liquid level of anti-flammability liquid, and after penetrating anti-flammability liquid with the form of bubble, enter the cavity between gas inlet pipe and sleeve pipe, in coal gas, the micro liquid of entrained with is through coagulating sedimentation after buffering in sleeve pipe, come back in fluid-tight body, avoid the liquid entrainment people combustion system in fluid-tight; Last coal gas is flowed out by gas exit, enters combustion system.Its deficiency existed is, need larger gas pressure to carry out normal air feed to go out water seal pressure, on the house steward that pressure is higher, effect is better, when on the gas pipeline in being applied to, before the burner of low pressure, the too complicated and gas supply capacity of structure declines greatly, and inapplicable.
Also researcher is had to be that problem that flame propagation velocity is greater than the air-flow rate of outflow is developed and reached by improving combustion gas spouting velocity the object controlling tempering according to causing the basic reason of tempering.If Chinese patent notification number is the document of CN204006010U, it discloses " a kind of combustor nozzle being applicable to low-pressure fuel gas ", it utilizes the structure of baffling centrum to form speed power sealing, when there is tempering phenomenon, the gas flame of reverse back runs into the combustion gas of multilayer baffling centrum ejection, thus stop flame to be back in gas header pipe, prevent the appearance of the dangerous situations such as blast.But it is large to there is fuel gas flow drag losses in it, causes the phenomenon of gas supply conduit scarce capacity.
Except arranging fire retardant device to prevent except tempering between gas pipeline and burner, also also have and adopt tempering automatically to detect shearing device to be used as the technical measures of tempering safety, if China Patent Publication No. is the document of CN103335314A, it discloses " a kind of burner anti-backfire system, it is by arranging combustion tube fire monitor equipment, range sensor, feed pipe magnetic valve, alarm etc., when fire monitor equipment detects flame, when the position of tempering measured by range sensor, pass the signal to master control system, feed pipe magnetic valve is opened and is put out a fire by master control system.China Patent Publication No. is the document of CN1344885A, it discloses the technical measures of one " coke oven gas burner ", it is by being provided with back-fire relief gas entrance, and when there is tempering in pipeline, it by spraying nitrogen or blast furnace gas carries out fire-retardant in pipe.
Technical measures disclosed in above-mentioned document, by analysis, all need additionally to increase back fire flame checkout gear, cooling water/inert gas piping system, cooling water/back-fire relief gas interlock automatic open device, cause system complex, equipment cost higher, and gas supply capacity is not enough.
