Light-hydrocarbon fuel is heated to certain temperature.But this needs to pay certain energy resource consumption.And in the thermal technology in above-mentioned each field
Stove in process of production, can produce it is substantial amounts of in, low temperature waste gas, the waste gas exhaust temperatures of indivedual stoves even can be higher.This
The quantity of portion waste heat is sufficient for needed for most light-hydrocarbon fuel gasifications.Once realizing this process goal, not only may be used
To reduce particulate pollutant and NOxEmission level, simultaneously because the raising of fuel temperature, also simultaneously by a part of physical thermal band
Enter burner hearth, on the premise of same process goal is completed, the unit consumption of fuel has the reduction of suitable amplitude.
Light-hydrocarbon fuel calorific value is very high, in liquid, and its calorific value is in 46000KJ/KG or so, and at gaseous state (standard state), its
Calorific value is even more to reach 160000KJ/Nm3 or so.Making the fuel of so high heating value should burn fully, and can meet environmental protection row
Put, the undoubtedly requirement to combustion equipment is high.And in current burner in the market, fully burning and ring can be met simultaneously
Protect the extremely rare of emission request.Therefore, fuel value is adjusted, is also this while meeting the abundant fuel of fuel and environment protection emission
