The invention discloses a fluorine capturing fuel with enwrapped stone coal as main material and its production method, wherein cured and burned dolomitite or burned limestone, anthracite duff and clay are mixed by a finite proportion and coated outside the stone coal, and the end product through further airing. The invention realizes high fluorine-fixing rate, sulfur-eliminating ratio and dust-depositing rate, the problem of air pollution of vast amount of fluoride and sulphide produced by stone coal combustion is solved substantially. 本发明为一种包裹石煤固氟燃料及其制法：由经熟化的烧制白云岩或烧制石灰岩、无烟煤粉、粘土三种组分按照一定比例混合后包裹于石煤外面，晾干后得到。本发明对高氟石煤煤块的使用找到了全面合理和实用的固氟技术。本发明固氟率、除硫率以及降尘率高，基本解决石煤燃烧时放出大量氟化物、硫化物造成空气污染问题，具有巨大的环境-社会效益。本发明所用的石煤组分在我国燃煤型中毒地区广泛使用，实用性好，适合用于燃煤型中毒地区农村偏远地区地炉、炊炉等各种民用炉灶，使用方便，成本低，不会增加农民经济负担，易于在燃煤型氟中毒地区推广。
