Problems solved by technology

The production of peanut shell briquette fuel usually needs to go through processes such as crushing, drying, grinding, briquetting, cooling and packaging. At present, the more common briquetting device used for briquetting peanut shells on the market is ring die briquetting However, in the production process of the ring die briquetting machine, the peanut shells tend to generate a lot of heat under the friction of the ring die and the pressure roller, which makes the temperature of the ring die continue to rise, resulting in unstable peanut shell molding and easy blockage of the ring. die hole
The current common production method of peanut shell briquettes also has the following disadvantages: one is that the production process is relatively cumbersome, the production efficiency is low, the calorific value of the produced peanut shell briquettes is uneven, and the combustion efficiency is low; the other is that the produced peanut shells The briquette is not very compact, the calorific value of combustion is low, and it is not easy to burn; the third is that binders are generally required to be added during the production process, which is not very environmentally friendly
In addition, when the currently common biomass solid shaped fuel is burned in the boiler, the flue gas produced contains molten or semi-molten alkali metal silicate, which condenses and accumulates when it touches the inner wall of the boiler, eventually causing severe The phenomenon of ash accumulation and slagging will not only affect the thermal performance of the combustion equipment, but also endanger the safety of the combustion equipment
