How much sulfur dioxide is emitted into the atmosphere from the flue gas of a thermal power plant after desulfurization, per 1 ton of standard coal burned? Logically, there should be a fixed proportional relationship. I wonder if anyone who has done similar work is available to share their insights!
It depends on the sulfur content in the coal itself and the desulfurization efficiency to determine this.
Standard coal, also known as coal equivalent, has a unified calorific value standard. Our country specifies that the calorific value of each kilogram of standard coal is 7,000 kcal. Energy of different varieties and contents is converted into standard coal with a calorific value of 7,000 kcal per kilogram, based on their respective calorific values. Your question concerns the amount of sulfur dioxide; the generation of sulfur dioxide depends mainly on factors such as the sulfur content in coal and the combustion efficiency of the boiler. Therefore, your question has no solution~~~~:D
Some people have also spent a lot of time trying to figure out this question. But data is needed: 1 The percentage of carbon, sulfur, and nitrogen in the fuel, as indicated by A. 2 The oxidation coefficients of carbon, sulfur, and nitrogen during complete combustion, as indicated by B. 3 The conversion rates of carbon to CO2, sulfur to SO2, and nitrogen to NOx, as indicated by C. Then calculate: A*B*C*44/12 ； A*B*C*64/32, etc. Note that when using standard coal for calculations, energy values such as GJ are typically used to represent it; therefore, you must multiply the actual type of fuel by an conversion factor in order to convert it into standard coal.
