Summary: | The invention relates to a process for preparing a clean synergist for saving coal, desulfurization and cleaning coke. Active calcium oxide and magnesium hydrate are mixed and added with sodium carbonate, ferrosilicon powders, manganese dioxide, strontium carbonate and barium hydroxide in turn and finally added with active carbon and evenly mixed to prepare the clean synergist which comprises the following compositions in percentage by weight: 20 to 30 percent of the active calcium oxide, 9 to 12 percent of the magnesium hydrate, 12 to 20 percent of the sodium carbonate, 8 to 10 percent of active carbon, 12 to 15 percent of the ferrosilicon powders, 8 to 12 percent of the manganese dioxide, 3 to 5 percent of the strontium carbonate and 5 to 7 percent of the barium hydroxide. on the premise of unchanging the prior coal burning process and equipment of various boilers and the prior smoke exhaust process and equipment, the clean synergist of the process is only needed to add according to the physicochemical inde |
