Problems solved by technology

However, the burden correlation between the combustion-supporting effect and the sulfur reduction efficiency, and the high-temperature re-decomposition of calcium-based sulfur fixation lead to a decrease in the sulfur reduction efficiency, especially the use of inferior coal, the pollution reduction of high-sulfur coal, and the use of expensive equipment for flue gas desulfurization after combustion Key issues such as cost burden have not been well resolved, resulting in unsatisfactory energy-saving and environmental protection effects of coal-fired
So far, no coal-saving sulfur-fixing agent with gray carbon shale as the raw material component has been published

Embodiment Construction

[0009] The shale coal-saving sulfur-fixing agent of the present invention is composed of the following raw materials: carbonaceous shale rich in silicon and calcium, 10-20% each of industrial sodium chloride and calcium oxide; 5-15% each of potassium perchlorate and sodium nitrate; Sodium, potassium permanganate 2-5%; water 5-10%; catalyst 1-3%. The above raw materials are prepared in different proportions according to the heat and sulfur reduction requirements of different users such as thermal power plants, cement plants, hot steam boilers, brick kilns and civil briquettes, and are mixed evenly, stacked, and then bagged for later use. This product can be stored for 2-3 years as long as it is not soaked in water.

[0010] With this shale coal-saving sulfur-fixing agent, it can be evenly mixed into the burning coal according to the dose of 2-3% of the coal consumption, and put into the furnace for burning, and the use effect can be achieved. In order to reduce labor troubles ...

Abstract

The invention relates to a novel coal-saving sulphur fixing agent comprising special material and using technology thereof, belonging to product of the field of coal energy-saving and burning sulphur fixing technology. This invention is composed of stratified rock rich in iron, calcium, silicon, and charcoal, calcium oxide, potassium permanganate, potassium chlorate, potassium perchlorate, sodiumnitrate, sodium carbonate, special catalyst and water. The coal-saving sulphur fixing agent is mixed in the coal with a dosage about 2-3% of the coal. The coal-saving sulphur fixing agent boosts the coal burning thoroughly via increasing oxygen, catalytically burning effect to achieve coal-saving. The coal-saving sulphur fixing agent can realize normal burn of the hard-combustible low-heat coal and coal refuse, thereby fully using coal resource. Simultaneously saving coal, the coal-saving sulphur fixing agent fixes injurants such as sulfur dioxide generated by coal burning to reduce air pollution. By provincial detection, under a state of high combustion efficiency, and coal-saving above 17%, the sulphur fixing efficiency is still above 66%. Because of the use of shale material, the cost is reduced by two third which is beneficial to users.

Description

Technical field: [0001] The invention relates to an energy-saving and environment-friendly preparation that can fully burn coal and simultaneously fix harmful substances that pollute the atmosphere in coal slag, especially can effectively develop the calorific value potential of low-quality coal and reduce the hazards of high-sulfur coal. Energy saving and environmental protection technology fields. Background technique: [0002] So far, there have been more than dozens of reports on products and technologies that support combustion of coal and reduce sulfur, and have contributed to the advancement of science and technology in this field. However, the burden correlation between the combustion-supporting effect and the sulfur reduction efficiency, and the high-temperature re-decomposition of calcium-based sulfur fixation lead to a decrease in the sulfur reduction efficiency, especially the use of inferior coal, the pollution reduction of high-sulfur coal, and the use of expen...
