一、概述高浓度水煤浆,是继“油煤浆”后开发的一种可以完全代油燃烧的流态燃料,由70%左右的煤、30%左右的水及少量添加剂配制而成。自八十年代以来,这项技术在国际上已受列了广泛重视。瑞典、美国、日本、西德、加拿大等十几个国家先后投入大量资金和人力进行开发研究。瑞典、美国已分别建成年产25万吨和20万吨的制浆厂,并在20蒸吨/时和30蒸吨/时的锅炉中进行了燃烧试验。随着四化建设的迅速发展,我国对石油的需求量也在不断上升。虽然每年石油产量都有所增加,但仍然供不应求.可是每年却有3000多万吨油品被电力、化工、冶金等行业的各种炉窑作为燃料烧掉。我国煤炭资源丰富,品种
I. Overview High concentration CWS is a kind of fluid fuels that can be completely substituted for oil after the “coal slurry”. It is made up of about 70% coal, about 30% water and a small amount of additives. Since the 1980s, this technology has received extensive international attention. Sweden, the United States, Japan, West Germany, Canada and other countries have invested a lot of money and manpower to carry out research and development. Sweden and the United States have respectively built pulp mills with an annual output of 250,000 tons and 200,000 tons and conducted combustion tests in 20 steam tons / hour and 30 steam tons / hour boilers. With the rapid development of the four modernizations, the demand for petroleum in our country is also on the rise. Although oil production has increased each year, it is still in short supply, but more than 30 million tons of oil are burned by various kilns in the power, chemical and metallurgical industries every year. China is rich in coal resources and varieties
