The invention discloses a catalyst capable of promoting burning of a mixture of sludge and pulverized coal. The catalyst is characterized in that the mixture of the sludge and the pulverized coal and methylcyclopentadienyl manganese tricarbonyl and N,N-dimethylformamide are mixed for burning, thereby being capable of improving the burning efficiency of the sludge and pulverized coal mixture and reducing the firing temperature and the burnout temperature. In the catalyst, the sludge includes water supply sludge, domestic sewage sludge and industrial wastewater sludge, and the pulverized coal comprises lignite, bituminous coal and kikenny coal; and when the mass fraction of the sludge is 15-25% and the mass fraction of the pulverized coal is 75-85% in the mixture of the sludge and the pulverized coal, the catalytic effect is the best. The method and the product are hopefully applied to various large and small burning furnaces.
Description
Technical field: [0001] The present invention relates to a method and a catalyst for promoting the combustion of sludge and coal powder mixture, specifically, the method and additives can reduce the ignition temperature and burnout temperature of the sludge and coal powder mixture. technical background: [0002] In recent years, sludge incineration technology has been favored at home and abroad, and many sludge incineration plants in many countries have been put into use. Due to the low calorific value of silt, scientific and technological workers are currently burning pulverized coal and silt together, and have carried out a lot of work in researching the ratio of silt and pulverized coal, combustion technology, boiler improvement, etc., and have achieved a series of results so far. However, in the research on the mixed combustion of sludge and pulverized coal, a lot of work has been done on the combustion process and boiler improvement, but there is not a lot of research o...
