Embodiment 1
[0013] Embodiment one: the composition of the sludge compound fuel that the present invention develops comprises 10 parts of ammonium nitrate, 200 parts of sludge or lime mud, 200 parts of coal dust, 5 parts of potassium permanganate, 3 parts of ferrous sulfate, 10 parts of For sodium chloride, the above parts all represent parts by mass.
[0014] The method for preparing composite fuel is as follows: (1) Evenly mix 10 parts of ammonium nitrate, 200 parts of sludge or white mud, 200 parts of coal powder, 5 parts of potassium permanganate, 3 parts of ferrous sulfate, and 10 parts of sodium chloride , mechanically stirred at room temperature for 30 minutes, and the above parts all represent parts by mass;
[0015] (2) Extruding the processed mixture in (1) to obtain a finished composite fuel product. Using the above-mentioned fuel test, its calorific value can reach about 3000 calories, and it is fully combustible and easy to burn when in use.
Embodiment 2
[0016] Embodiment two: the new fuel that the present invention develops comprises 50 parts of ammonium nitrate, 400 parts of sludge or lime mud, 400 parts of coal dust, 35 parts of potassium permanganate, 20 parts of ferrous sulfate, 25 parts of sodium chloride, 50 parts of kaolin, 10 parts of potassium sulfate, and 10 parts of sodium carbonate, all of the above parts represent parts by mass.
[0017] The method for preparing composite fuel is as follows: (1) After uniformly mixing the above-mentioned components, mechanically stir for 30 minutes at room temperature, and the above-mentioned parts represent parts by mass;
[0018] (2) Extruding the processed mixture in (1) to obtain a finished composite fuel product. Using the above-mentioned fuel test, its calorific value can reach about 3200 calories, and it is fully combustible and easy to burn when in use.
[0019] The present invention obtains through a large amount of tests when selecting suitable composition and proporti...
Embodiment 3
[0020] Embodiment three: the new fuel that the present invention develops, its formula comprises 35 parts of ammonium nitrate, 600 parts of sludge or lime mud, 500 parts of coal dust, 50 parts of potassium permanganate, 40 parts of ferrous sulfate, 40 parts of chlorine Sodium chloride, 20 parts of potassium sulfate, 30 parts of sodium carbonate, 200 parts of kaolin, the above parts all represent parts by mass. The fuel application test of this embodiment records that its calorific value is 3500 calories.
[0021] The preparation method is the same as in Example 2.
[0022] When preparing fuel, in order to better extrude the step (2), you can first test the water content of the coal powder to ensure that the water content is between 12-20% after mixing, but generally this step is not necessary , depending on the actual situation, the water content can be freely controlled, as long as it is convenient for the subsequent steps to be extruded.
