The meaning of straw briquetting fuel

Straw briquetting fuel is a modern clean fuel that uses new technology and specialized equipment to compress and carbonize various crops such as straw, sawdust, peanut shells, corn cobs, rice straw, wheat straw and bran, tree branches and leaves, licorice, etc., without the need for any additives or binders. It can solve the basic living energy needs in rural areas and increase the income of farmers. It is also an emerging specialized fuel for biomass power generation, and straw briquette fuel can be directly used in traditional coal-fired boiler equipment in cities, replacing traditional coal. According to the prediction of the International Renewable Energy Organization, the reserves of underground oil, natural gas, and coal can only be used for about 60 years at current extraction and utilization rates. Therefore, straw briquetting fuel is an important development direction for future renewable energy. With the global energy shortage, the market demand and profit margin for straw briquetting fuel will be immeasurable
The main technical parameters of straw briquette fuel: density: 700-1400 kg/cubic meter; Ash content: 1-20%; Moisture ≤ 15%. Calorific value: 3700-4500 kcal/kg; The calorific value of straw briquette fuel varies depending on the type of straw. Taking corn straw as an example: its calorific value is about 0.7-0.8 times that of coal, which means that a 1.25t corn straw briquette fuel block is equivalent to the calorific value of 1T coal. The corn straw briquette fuel is burned in a matching down burning biomass combustion furnace, and its combustion efficiency is 1.3-1.5 times that of a coal-fired boiler. Therefore, the heat utilization rate of 1T corn straw briquette fuel block is equivalent to that of 1T coal.
