Embodiment Construction

[0022] Embodiment; Prepare clean coal catalyst medium of the present invention by following formula (weight percent) and described production process, and this product is pink powder:

[0023] Sodium chloride 57.2, magnesium chloride 25, manganese borate 3, potassium permanganate 3.8, potassium chlorate 5, oxides of copper, iron and titanium 3, surface active additives and antioxidant additives 3.

[0024] Its use method is as follows: add 0.3% catalytic media per ton of coal and dissolve in 10 times of water, and then mix and stir with coal.

[0025] According to comparative measurements by authoritative departments, under the condition of a 4t steam boiler, the calorific value of coal increases by 1200-1600 kcal / kg, which provides conditions for the large-scale use of low-quality coal with a calorific value of 1500-4000 kcal / kg; When it is 77%, the coal saving rate is still > 20%; the furnace temperature can be increased by 50-100°C; the carbon content of cinder can be reduc...

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

Technical field: [0001] The invention relates to a fine chemical product, in particular to 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 their ignition points, sulfur content, slagging, and burnout indicators. Forming agent and sulfur fixing agent are added to produce clean coal with different properties, better combustion and less pollutant emissions. [0003] However, how to further improve the combustion qualit...
