Abstract

The invention discloses a novel water-based coal combustion improver and a synthesis method thereof. The novel water-based coal combustion improver consists of the following components in parts by weight: 5-10 parts of potassium permanganate, 3-8 parts of potassium chlorate, 8-12 parts of borax, 5-10 parts of manganese dioxide, 5-10 parts of iron sesquioxide, 45-55 parts of suspending agent and 10-30 parts of water, wherein the suspending agent is prepared by reaction among water, soluble cellulose, a sodium hydroxide solution and water glass. The synthesis method comprises the following steps: preparing the suspending agent, and synthesizing the novel water-based coal combustion improver in a reaction kettle by utilizing the raw materials. By the novel water-based coal combustion improver, the ignition temperature, burnout temperature and relative burnout time of coal can be effectively reduced, the combustion rate of the coal is improved, the furnace temperature is improved, the carbon content of ash is greatly reduced, and the thermal efficiency of the boiler is greatly improved. The synthesis method is simple and easy to operate and has low requirement on equipment and personnel operation and can be popularized and used in a large scale.

Description

[0001] technical field [0002] The invention relates to a novel water-based coal-burning combustion aid and a synthesis method thereof. Background technique [0003] China is the largest coal consuming country in the world, and it is also one of the few countries in the world whose energy consumption is dominated by coal. Since the reform and opening up, my country's economy has developed rapidly, but the problems of high energy consumption per unit of GDP and the resulting high intensity of pollutant emissions have increasingly restricted the sustainable development of my country's social economy. Therefore, energy conservation and emission reduction have become the priorities of governments at all levels Constraint assessment indicators. As an important energy-saving and emission-reducing product, the development and research of coal-fired combustion accelerants have been active in the past decade, and some products have been used in industrial production; in addition, wi...
