Example Embodiment

[0021] Example: The clean coal catalyst media of the present invention is prepared according to the following formula (weight percentage) and the production process:

[0022] Sodium chloride 57.2, magnesium chloride 25, manganese borate 3, potassium permanganate 3.8, potassium chlorate 5, copper iron titanium compound 3, additive 3.

[0023] The method of use is to dissolve it in 10 times the water at a weight ratio of 0.3% per ton of coal, and then mix and stir with the coal.

[0024] According to the actual measurement by authoritative department, under the condition of 4t steam boiler, the calorific value of coal is increased by 1200-1600 kcal / kg, which provides conditions for the massive use of inferior coal with a calorific value of 1500-4000 kcal / kg; in boiler thermal efficiency When it is 77%, the coal saving rate is still more than 20%; the furnace temperature can be increased by 50-100℃; the carbon content of cinder can be reduced to about 5%, and the discharge of cinder ...

Abstract

The clean coal burning catalyst consists of composite hydrogen-storing alloy, alkali metal chloride, alkali earth metal chloride, boride, alkali metal oxidant, iron and manganese oxidant and other additive. The production process includes preparation of composite hydrogen-storing alloy, and the composition of coal burning catalyst. The clean coal burning catalyst can coal burning efficiency and reduce pollution, and its use makes it possible to use high-sulfur and low-heat value coal in producing briquette, leading in low coal burning cost.

Description

[0001] Technical field: The present invention relates to a fine chemical product, specifically an additive for burning coal or clean coal and its production process. Background technique: [0002] Coal is an important energy and raw material, and is the main fuel for industrial boilers. However, the traditional extensive coal burning method has many disadvantages, such as high-quality coal cannot be burned, low-quality coal cannot be used, and pollutant emissions have a serious impact on the environment. In order to overcome the above shortcomings, the current practice is to mix different coal types in a certain ratio according to their combustion characteristics, calorific value, volatile matter, and combustion indicators such as ignition, sulfur content, slagging, and burnout. And add forming agent and sulfur fixing agent to produce clean coal with different performance, more complete combustion and less pollutant emission. [0003] However, how to further improve the combu...
