Abstract

The invention relates to a preparation method for a coal combustion improver. After common coal is added with coal additives for combustion, the effect of energy saving and emission reduction is obvious and effective. The preparation method comprises the following steps that: 1. high-stability sodium chlorate and potassium chloride react with each other to produce potassium chlorate when water is added and the sodium chlorate and the potassium chloride are dissolved; 2. leavening agent sodium acetate is introduced to conduct base exchange with humate in coal, low ignition point humate is produced and the ignition performance of the coal is reduced; and 3. ferric oxide required by the formula is compound insoluble in water. Thereby, ferric chloride and calcium oxide are used to react with each other to produce ferric oxide when water is added and the ferric chloride and the calcium oxide are dissolved. Other products in the market do not at all have the preparation and application characteristics of the three compounds.

Description

technical field [0001] The invention relates to a preparation method of a coal-burning combustion aid. After the ordinary coal is burned with the addition of a coal-fired combustion accelerant, it can obviously and effectively achieve the effect of energy saving and emission reduction. Background technique [0002] With the continuous and rapid development of my country's economy, the acceleration of urbanization and the continuous increase of population, the annual consumption of coal has increased significantly year by year. Coal combustion is the main way of coal utilization. my country's energy structure is mainly based on coal, and the coal used for direct combustion is about 800 million tons per year. Cause serious pollution to the environment. China's use of coal could produce more global warming gases than all industrialized nations combined in the next 25 years, five times more than the Kyoto Protocol limit. [0003] To sum up, how to efficiently use resources an...
