Study on technique transference and the method of prevalence and enlightenment for coal-biomass briquette

Coal-biomass briquette (BB) that can efficiently fix S02 from combustion of low grade raw coal and pulverized waste coal was developed. And it was effort to investigate, possibility of BB technology as a prevention measure of acid rain, based on combustion test, performance test and diffusion model concept intended for region of southwest, northeast, inland and northern city of China. From this possibility test, it was obvious that we can not only get revenue, but also reuse waste coal, and reduce particulate matter and S02 if we construct BB factory which can has annual total production amounts of more than 100,000 tons. And from economic estimation, it calculated product cost 130- 250 yuan (ca. equivalent of 1,750- 3,400 yen) per ton of BB which was comparable to commercial high grade coal. But variety and distribution of biomass depend on region characteristic, and transfer cost also is an impact factor. In future, we should considerate continuously technique transference and the method of prevalence and enlightenment, and it will be expected that Japan-ehina cooperative research that aims to realize the model concept, reap a rich harvest
