Yixing, Jiangsu, after comparing the heat source of biomass hot blast stove and diesel heat source, decided to promote the use of "straw coal" in the grain drying process next year. Prior to this, the source of heat for most grain drying equipment in Yixing City was coal-fired or oil-fired. The resulting environmental pollution should not be underestimated. Accelerating the reform of the clean heat source of grain drying equipment has become an urgent task. The city's water conservancy and agricultural machinery department has compared and analyzed the drying costs of rice. The birth material particulate hot blast stove is more suitable for the drying of local rice, not only at a lower cost, but also reducing environmental pollution.
Recently, the results of comparative experiments on drying of biomass pellet hot blast furnace heat source and diesel heat source carried out by the city's water conservancy and agricultural machinery department showed that the biomass pellet heat source reduced the cost by 0.1 yuan/kg compared with the diesel heat source drying rice. Next year, the city is expected to promote the use of "straw coal" in the grain drying process on the basis of this experiment.
In recent years, grain drying equipment has become a rigid demand for many large agricultural machinery and agricultural machinery cooperatives. At present, the city has nearly 400 sets of various types of grain drying equipment. In view of the investment and operating cost reasons, except for a small part of the use of gas, electric drying, the vast majority of the heat source of grain drying equipment, the main use of coal or fuel, the resulting environmental pollution can not be underestimated. In order to speed up the reform of the clean heat source of grain drying equipment, the municipal water conservancy and agricultural machinery department organized the technical backbone and selected the Yongping Agricultural Machinery Service Cooperative in Panjiaba Village, Xushe Town as a test site to carry out the drying of biomass pellet hot blast furnace heat source and diesel heat source. Contrasting the test, collecting and recording the test data of the dryer and comparing the drying cost of rice. The test results show that the operation of the biomass particle hot blast stove is simple and the hot blast temperature can be controlled intelligently, which is suitable for the drying of local rice. Under the same conditions, for each kilogram of rice dried, the heat source of biomass particles is 0.1 yuan less than that of diesel heat sources.
According to the relevant technical personnel of the city's water conservancy and agricultural machinery department, the biomass pellet hot blast stove not only has good regional adaptability, use reliability, and economy, but also uses biomass pellets as fuel to reduce environmental pollution and comprehensive utilization of straw in our city. Can also play a role in promoting. During the summer harvest period next year, the department will focus on conducting a comparative test on the heat source of biomass pellet hot blast furnace and the drying of diesel heat source, form an analysis report, and accelerate the application of “straw coal†using straw as a biomass pellet fuel.
