Production and Application of Coals for Chain Grate Boilers

摘要

To formulate the national standard "Technical Conditions of Coals for Chain Grate Boilers", we surveyed 15 state-owned mine bureaus, some typical fuel companies and environmental protection bureaus in 8 provinces and cities such as Beijing, Shanghai and Zhejiang. By survey, the domestic coal production and application conditions were basically obtained. At present, mine bureaus mainly produce coals for electric power generation, which have difficulties in coal production particularly for chain grate boilers. Environmental protection is always placed on the first position when coal grade is checked and evaluated in various provinces and cities.
