Description
Technical field
The utility model is related to liquid fuel gasification combustion field, more particularly to a kind of burning of liquid light hydrocarbon fuel gasification
System.
Background technology
Fossil fuel forms some poisonous, harmful materials in combustion, inevitably.Different fuel shapes
The quantity of poisonous, the harmful material formed after state, burning is different.Even same fuel, when it is with solid-state, liquid
When being burnt respectively with three kinds of physical aspects of gaseous state, the emission level of its pollutant is also different.Specifically it is exactly, same heat
Construction equipment, use solid fuel pollutant emission level most serious when burning, during liquid fuel combustion, pollutant emission level time
It, during gas fuel combustion, pollutant emission level is most light.This is due to the secondary pollution and combustion that fuel is produced in burning
Expect that the controlled degree in burning is relevant, the fuel being more easily controlled, the secondary pollution that it is produced when burning is fewer.
Because fire coal is larger to environment environmental pollution, it is gradually backed out the arena of history and has become certainty.Natural gas
And lighter hydrocarbons are coal-fired preferable substitute products.Because coal-fired user region considerable part does not lay natural gas line,

Amount, SO2、NOxContent, during more than fired coal combustion, the dustiness of flue gas, SO2、NOxIt is low, the pollution to environment can be mitigated significantly,
Meet newest national requirements for environmental protection.
For light-hydrocarbon fuel, on the premise of fuel utilization efficiency is not reduced, how to reduce secondary pollution row as far as possible
Put, be urgent problem to be solved.This technology be with light-hydrocarbon fuel normal temperature, normal pressure for liquid, when temperature exceed certain temperature when,
Most component gasifications in light-hydrocarbon fuel, the characteristics of remaining ingredient weight is less than 10% is starting point.
During using light-hydrocarbon fuel as fuel, most light-hydrocarbon fuels are burnt with gaseous form, are easier to realize, it is only necessary to
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
