What should be paid attention to in the use of briquette composite binder?

Briquette binder (also known as briquette binder, briquette binder, briquette composite binder, etc. ) is a kind of admixture, which can bond (bond) and strengthen powdered fuels such as pulverized coal, which is beneficial to forming blocks; Powder or liquid briquette auxiliary raw materials make briquette have specific shape and performance after molding; Mainly used in briquette processing technology to play an auxiliary role. Briquette binder is the key auxiliary material to determine the quality of briquette. The briquette binder is formed by complex chemical reactions between inorganic substances and various organic chemical raw materials. After adding pulverized coal, it quickly forms a needle-like network structure, which makes briquette (briquette) have high cold and hot mechanical strength and thermal stability. High moisture-proof, waterproof performance and immersion strength; The furnace has high combustion value, high thermal strength after combustion, low falling and crushing rate, no ash, no pollution and simple operation. Characteristics of briquette binder: 1, strong adhesion, good fluidity and easy dispersion of coal particles. 2, no increase in ash, no reduction in fixed carbon, and no influence on slagging. 3, the molding rate is high, and the cold and hot strength is good. 4, convenient use, small addition amount and low cost. 5, wide application range, various gasification briquettes in chemical fertilizer plants. 6, environmental protection and no pollution, improve the gas conversion rate.

The advantage of coal gasification is 1. The briquette can replace lump coal for gasifier in chemical fertilizer and chemical industry, which improves the utilization rate and added value of smokeless pulverized coal and promotes the process of resource integration and product structure adjustment in coal industry. 2. The gasification medium has uniform particles, good air permeability, fast ignition, full combustion, high thermal efficiency, low ash content, low sulfur content, strong thermal stability, high mechanical strength and certain waterproof effect. 3. The gasification briquette has uniform composition and stable calorific value, and can be used in primary furnace and secondary furnace after optimization, and the comprehensive thermal efficiency is improved by more than 15%. With the continuous development of briquette industry, binder has also become a hot topic. Dry humic acid is also used in petrochemical industry to process briquette, cellulose is used in papermaking and chemical industry, and it is also used as briquette binder. They can only be used as auxiliary materials, otherwise the cost of briquette is too high for the market to accept, and the thermal stability of briquette is not good. ?
