某电厂结合HG-1165/1745-YM1型锅炉的特性，进行以燃烧烟煤为主，掺烧褐煤的试验。文章提出了掺烧褐煤的最优改造技术方案，讨论了褐煤掺烧技术应用中所面临的问题，并对掺烧褐煤的经济性进行分析。

Combined with the features of HG-1165/1745-YM1 boiler in a power plant, the tests for burning bituminous coal mixed with lignite is preformed. For mixing lignite, the optimal transformation is proposed, the technical problems occurring in the engineering practice discussed, and the corresponding economics analyzed.
