Principle and function of straw briquette machine
Straw briquette machine refers to the rural corn stalks, wheat straw, cotton stalks, rice straw, rice husk, peanut shells, corn cobs, branches, leaves, sawdust and other crops, solid waste as raw materials, after crushing, pressurization, densification of the molding machine used for the machine, that is, "straw briquette machine". After molding straw charcoal briquette, small volume, specific gravity, combustion resistance, easy to store and transport, the volume is only equivalent to 1/30 of the original straw, is the same weight of straw 10-15 times, its density is 0.9-1.4g/cm3, calorific value can reach 3500-5500 calories between, is a high volatile content of the solid fuel.
Straw briquette machine is widely used for corn stalks, wheat straw, cotton stalks, rice straw, rice husk, peanut shells, corn cobs, tree branches, leaves, sawdust and other crops. We all know that strengthening the development and utilization of renewable energy is the way to cope with the increasingly serious energy and environmental problems, but also the way to the sustainable development of human society.
From the point of view of the output of straw resources, the majority of rural areas and townships have a large output and wide range of various straw. According to statistics, in 2006 China's production of crop straw amounted to 570 million tons, mainly including the straw of corn, wheat, cotton, rice, barley and oilseeds, of which 153.43 million tons of corn straw, 105.29 million tons of wheat straw and 178.91 million tons of rice straw. The total amount of crop straw produced in China every year accounts for about 20%-30% of the world's total amount of straw after hot pressing and molding to reach a certain density, and then burned to improve the combustion temperature and heat utilization, saving time, reducing environmental pollution, can make the straw coal become a low-cost, high-calorific value of environmental protection and energy products.
