近年来,许多国家已把发展型煤作为控制燃煤污染的主要对策,并取得了显著的节能效果。我国对工业型煤的研究已从实验室研究进入中试研究,建立型煤示范及推广应用阶段。在四川的能源消费结构中,煤炭占73％。其中以原煤形式直接燃烧的约占62.26％,由于重庆地区所产的无烟煤挥发份低,含硫量高,灰份高,直接燃用造成了严重的大气污染。为此,我们在对以高硫无烟煤为主要原料的工业型煤的成型工艺研究的基础上,对高硫无烟煤成型工艺进行了深入研究和进一步完善。目的为提高型煤的燃烧性能,解决固硫、固灰的环保问题,力争在生活锅炉中推广使用。
In recent years, many countries have taken the development of briquette as a major measure to control coal-fired pollution and have achieved remarkable energy-saving results. China’s research on industrial briquette has entered the pilot study from laboratory research, and established briquette demonstration and popularization and application stage. In Sichuan’s energy consumption structure, coal accounts for 73%. Among them, 62.26% is directly burned in the form of raw coal. Due to the low volatility of anthracite produced in Chongqing, high sulfur content and high ash content, the direct burning caused serious air pollution. Therefore, on the basis of the research on the forming process of industrial briquette with high-sulfur anthracite as the main raw material, we conducted in-depth research and further perfected the forming process of high-sulfur anthracite. The purpose is to improve the combustion performance of briquette, to solve the sulfur-fixing, solid ash environmental problems, and strive to promote the use of domestic boilers.
