Feasibility Study Of The Power Plant Haze Been To Prevent Spontaneous Combustion And Sealed

This article main union with the coal Tashan ore's special details (which has pit mouth power plant), After analysis, in the pit mouth power plant flue gas principal constituent N₂ occupies 79%, O₂ to occupy 4.5%, CO₂ to account for 16.5%, in addition also includes few air pollutants and so on SO₂, NO₂, CO, if can its injection well under the worked-out section, both may replace the note nitrogen effective prevention and the control coal spontaneous combustion fire, saves, because the system nitrogen creates energy waste, and may realize to the pollutant seals, the protection environment goal.First, application of the spontaneous combustion tendency of coal determined to measure the flue gas of coal on the main gas composition (O₂, N₂, CO₂) absorption capacity, may of carbon dioxide out of coal and coal gas adsorption than oxygen and nitrogen adsorption on the large amount of 2 5 times, power plant flue gas into the coal face and the mined-out area, the coal will be absorption of carbon dioxide gas, thereby preventing coal contact with oxygen, effective to prevent the oxidation of coal spontaneous combustion. Then the union power plant situation produces the spirit, the noxious gas density through the analysis and so on, judges transportation's feasibility,and further confirms the gas injection to be able to replace the note nitrogen. In order to realize this idea, further establish the gas injection craft, designs takes is mad the plan, lays down the pipeline, finally through budgets generally, compares with the note nitrogen economic efficiency, in initial investment's situation, the fund will save will amount to 13,117,028 Yuan; After initial investment, the normal work consumes one year to be possible to save the expense 900,000 Yuan.
