Description
Technical field
The utility model belongs to coal-burning boiler technical field, relates to a kind of combustion system of Boiler Mixed Burning waste gas, the combustion system of the blue charcoal waste gas of especially a kind of blended burning of coal fired boiler.
Background technology
Blue charcoal is widely used in the industries such as ferroalloy, iron and steel, chemical industry.In recent years, along with the continuous increase of market demand, blue charcoal industry development is rapid, and production capacity is in quick growth.China, as developing coal big country, is also the maximum Lan Tan producing country in the whole world, accounts for the blue charcoal market share that the whole world is over half.Shaanxi Province is the current domestic main place of production of blue charcoal, and annual production, at about 4,000 ten thousand tons, accounts for more than 50% of national total output.According to the condition of production of coal mine base in northern Shaanxi Lan Tan enterprise of Shaanxi Province, blue charcoal per ton need consume about 1.8 tons of raw coal, raw coal per ton can produce 1200 ~ 1300 cubic metres, the blue charcoal waste gas of calorific value equivalent 1500 ~ 2000 kilocalories/cubic meter when being converted into blue charcoal, the blue charcoal waste gas of annual association 860 ~ 930 cubic metres in coking, except personal, take the emptying burning of flare tip or directly diffuse for about 700 cubic metres in the by-product waste gas that raw coal per ton transforms, blue charcoal waste gas about 500 billion cubic meter of annual outer row, amounts to standard coal about 1,000 ten thousand tons.If can actively utilize this resource, not only ten million ton of standard coal can be saved every year, and can effective decreasing pollution, to the cleaner production of promotion blue charcoal industry, realize recycling economy significant.
Refining semicoke or claiming in the technique of blue charcoal, coal is by a large amount of waste gas of association after middle low temperature distillation, by analysis, blue charcoal waste gas belongs to a kind of mist, and combustible component accounts for about 40%, mainly contains H
2, CH
4, CO, Lower heat value is generally at 1700-2000Kcal/Nm
3between, be about 25% of coal Lower heat value, ignition temperature is less than 500 DEG C, and can direct-fire burn, combustibility is excellent, can be used as fuel.
Utility model content
The purpose of this utility model is to overcome above-mentioned prior art shortcoming, there is provided a kind of by mixing the combustion system of burning blue charcoal waste gas in coal-burning boiler, solve the waste that blue charcoal waste gas directly discharges pollution on the environment and resource, promote Coke Industry cleaner production, realize the combustion system of the blue charcoal waste gas of blended burning of coal fired boiler of recycling economy.
For achieving the above object, the technical scheme that the utility model is taked is: comprise the blue charcoal exhaust piping for carrying blue charcoal waste gas, for carrying air duct and the coal-burning boiler burner hearth of air,
The front-back wall of described coal-burning boiler burner hearth has been arranged symmetrically with some groups of burners, and this burner communicates with coal-burning boiler burner hearth inside; Be provided with electronic ignition device on the burner,
The gas outlet pipeline of described blue charcoal exhaust piping, the outlet pipe of air duct are connected with air intake with the blue charcoal fuel gas inlet of burner respectively.
Often organize burner and comprise at least two gas burners be set up in parallel.
Described blue charcoal exhaust piping is provided with electric butterfly valve and rapid cut-off valve.
Described air duct is provided with electric butterfly valve.
The utility model has following beneficial effect: the utility model utilizes the combustion characteristics of blue charcoal waste gas, blue charcoal waste gas is used as fuel, substitute coal-fired, save fossil fuel, by burner, blue charcoal waste gas and air are sprayed in coal-burning boiler burner hearth, blue charcoal waste gas lights after-combustion by electronic ignition device with air after coal-burning boiler burner hearth mixes, and by simply transforming coal-burning boiler, is easy to realize.The utility model not only can solve the waste that blue charcoal waste gas directly discharges pollution on the environment and resource, and promote Coke Industry cleaner production, realize recycling economy, the utility model is simple for structure, initial stage drops into little, be not only the recycling to waste resource, and environmental benefit is very outstanding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is blue charcoal exhaust piping; 2 is air duct; 3 is burner; 4 is coal-burning boiler burner hearth.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details:
See Fig. 1, the utility model comprises the blue charcoal exhaust piping 1 for carrying blue charcoal waste gas, for carrying air duct 2 and the coal-burning boiler burner hearth 4 of air, the front-back wall of coal-burning boiler burner hearth 4 has been arranged symmetrically with some groups of burners 3, often organize burner 3 and comprise the gas burner that at least two of being set up in parallel join high-energy electron ignition gun, each burner 3 all communicates with coal-burning boiler burner hearth 4 inside; Burner 3 is provided with electronic ignition device, and the gas outlet pipeline of blue charcoal exhaust piping 1, the outlet pipe of air duct 2 are connected with air intake with the blue charcoal fuel gas inlet of burner 3 respectively.Blue charcoal exhaust piping 1 is provided with electric butterfly valve and rapid cut-off valve, air duct 2 is provided with electric butterfly valve.
The utility model is sent in coal-fired power station boiler by blue charcoal exhaust piping 1 by blue charcoal waste gas to be used as a kind of fuel mixing burning, one group of gas burner is symmetrical arranged respectively by the front-back wall at coal-burning boiler burner hearth 4, often group can arrange 2 ?3 gas burners (high-energy electron ignition gun joined by burner), blue charcoal waste gas is connected with burner by blue charcoal exhaust piping 1, then introduces a road combustion air.In in coal-burning boiler burner hearth 4, blue charcoal waste gas and air spray into after burner hearth mixes through burner and light after-combustion by burning torch.
Improved boiler can adapt to two kinds of burning operating conditions: 1) under boiler high load capacity operating mode (during 50% ~ 100% load), mix and burn blue charcoal waste gas, fire coal can be saved, reduce the consumption of a fossil energy, save fuel cost, the ratio of mixing burning can reach 20% ~ 30%, saves coal-fired effect clearly;
2) under boiler at low load operating mode (time below 50% load), coal-burning boiler generally adopt throw oil combustion-supporting, surely fire, due to the combustion characteristics that blue charcoal waste gas is excellent, mix and burn blue charcoal waste gas and can play the effect of combustion-supporting, steady combustion by replacing fuel oil.Mix in this way and burn blue charcoal waste gas, it is simple for structure, and the initial stage drops into little, be not only the recycling to waste resource, and environmental benefit is very outstanding.
