Liquid fire coal additive

Abstract

The invention provides a liquid coal-fired additive, which comprises the following raw materials in mass percentage: 0.5%-2% cerium nitrate, 1%-5% sodium chloride, 10%-50% sodium nitrate or potassium nitrate, 10%-30% Potassium chromate, the balance of deionized water. The liquid coal-fired additive provided by the invention can increase the combustion temperature and thermal efficiency, reduce the carbon content of the slag, reduce the emission of carbon dioxide and smoke in the slag, and make full use of waste coal. Save high-quality coal resources, thereby saving coal consumption and reducing environmental pollution caused by coal combustion. The liquid additive overcomes the shortcomings of solid addition. It only needs to add a powerful spraying device on the coal conveyor belt conveyor and the spraying amount is proportional to the amount of coal fed. The operation is convenient, the efficiency is high, and the spraying is uniform.

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...
