Liquid fire coal additive

Abstract

The invention provides a liquid fire coal additive. The liquid fire coal additive is prepared from the following raw materials by mass percent: 0.5 to 2 percent of cerous nitrate, 1 to 5 percent of sodium chloride, 10 to 50 percent o sodium nitrate or potassium nitrate, 10 to 30 percent of potassium chromate and the balance of deionized water. By adopting the liquid fire coal additive, the combustion temperature and heat efficiency can be improved, the carbon content of furnace slag can be reduced, the emission of furnace slag carbon dioxide and dust can be reduced, and the waste coal can be sufficiently utilized. The high-quality coal resource can be saved, so that the consumption of the coal is saved, and the environmental pollution caused by the combustion of coal can be reduced. The liquid additive also overcomes the defects of solid additives; and only a powerful spraying apparatus is needed on a coal conveyor belt and the spraying amount is in proportion to a coal loading amount, so that the operation is convenient, the efficiency is high, and uniformity in spraying is realized.

Description

technical field [0001] The invention relates to a fine chemical product, in particular to a liquid coal combustion additive. Background technique [0002] Coal is an important energy and raw material, and is the main fuel for industrial boilers. However, the traditional way of burning coal has many disadvantages, such as high-quality coal cannot be burned, low-quality coal cannot be used, and pollutant discharge has a serious impact on the environment. In order to overcome the above-mentioned shortcomings, the current practice is to mix different coal types in a certain ratio according to the combustion characteristics, calorific value, volatility, ignition, sulfur content, slagging, burnout and other combustion indicators of the coal type. Forming agent and sulfur fixation agent are added to produce clean coal with different properties, complete combustion and less pollutant emissions. [0003] However, how to further improve the combustion quality of coal, increase the f...
