Preparation method of fire coal improver

Abstract

The invention relates to a preparation method of a fire coal improver. After a fire coal additive is added into ordinary fire coal for burning, remarkable and effective energy-saving and emission-reducing effects can be achieved. Firstly, white polylol hexanediol in a solid state is adopted, polylol is added to enhance a combustion supporting function, the polylol hexanediol is prepared into a solid fire coal combustion improver together with other aids, and convenience is brought to transport and storage; secondly, sodium acetate serving as a swelling agent is introduced for performing base exchange with humate in coal to generate humate with a low fire point, so that the ignitability of coal is reduced; and thirdly, ferric oxide needed in a formula is a water-dissoluble compound, so that ferric oxide is generated by making ferric chloride and calcium oxide react in a water adding dissolving process in the invention, and the preparation and application characteristics of the three compounds are not possessed by other products on the market.

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...

Problems solved by technology

[0007] 4. There are a series of problems in the combustion of coal: the utilization of the calorific value of coal is low because of its large heat capacity, high ignition point, difficulty in ignition and heat transfer

Its basic unary reaction C+O 2 -----→CO 2 The activation energy is large, and the side reaction CO is easy to occur 2 +C-----→2CO, the thermal efficiency is greatly reduced
