Description
Technical field
The present invention relates to a kind of natural gas joint fuel exhaust gas to clean fusion agent high-pressure common rail premixing combustion apparatus.
Background technique
Recently, country, which proposes, " carries out Industrial Boiler kiln, heavy-duty diesel oil engineering truck, farm machinery, ship shipping oil
Discharge beyond standards special administration ", stage by stage complete rebuilding and improving task, in by the end of October, 2018 before, complete 10 steam the above combustion gas of ton
The transformation of boiler low nitrogen burning；The 1-10 that completes preceding in by the end of October, 2019 steams ton (steaming ton and 10 steaming tons containing 1) gas fired-boiler low nitrogen burning
Transformation；To the year two thousand twenty by the end of June before, existing non-electrical gas-steam boiler, hot-water boiler, layer burner and spreader stoker boiler are fully completed low
Nitrogen combustion retrofit；Flue dust, sulfur dioxide and nitrogen oxides reach 5mg/m3,10mg/m3,30mg/m3, and it is synchronous to create gas fired-boiler
Installation low nitrogen combustion apparatus simultaneously reaches discharge standard requirement；20 steamings ton/hour and the above gas fired-boiler will install the source of atmospheric pollution

Gas fired-boiler will install nitrogen oxides exhaust analyzer.
In everybody impression, natural gas is a kind of clean energy resource, why can still generate NOX pollutant, this is because
Gas fired-boiler combustion of natural gas temperature is more than that will start to generate a large amount of nitrogen oxides after 1000 DEG C.
Natural gas main component is alkane, and wherein methane accounts for the overwhelming majority, while also containing micro nitrogen impurity；Natural gas
Need air in combustion, and in air 80 parts be nitrogen, under room temperature, nitrogen is a kind of very stable gas, but in height
Nitrogen oxides will be generated under the conditions of temperature, nitrous oxides concentration affects PM2.5, and especially Heating Season energy consumption and winter is spread
The unfavorable double factor superposition of condition, influences whether the generation of nitrogen oxides.
According to calculating, the amount of nitrogen oxides that 1 ton of combustion of natural gas generates is 6.35 kilograms, and natural gas itself does not generate nitrogen oxidation
Object, only ignition temperature is very high, and high temperature produces nitrogen oxides, if it is possible to by burning point temperature control at 800 degree hereinafter, energy
Discharge amount of exhaust gas is enough greatly lowered, but the efficiency that burning utilizes also just reduces, this generates contradictions.
In fact, either coal-fired, combustion gas or fuel oil, can all discharge nitrogen oxides, but the weight as Ozone in Atmosphere
Precursor is wanted, the increase of nitrous oxides concentration will cause certain secondary pollution, but these can control, nitrogen oxides one
It is directly a class of pollutant of China's priority control.
