掺烧劣质低价煤是降低燃煤火电厂发电成本的主要措施之一，盘山发电公司选择了高水分、高硫分、低发热量的内蒙古劣质褐煤进行掺烧。为了确保锅炉燃烧的安全和经济性，在劣质煤大规模掺烧之前，进行了劣质煤与优质煤按1：3、1：1和纯褐煤3种掺配比例的磨制试验，证明劣质褐煤掺烧技术实际应用的可行性，并对掺烧劣质褐煤的经济性进行了分析，试验数据和分析结果可供同类机组掺烧借鉴。
摻燒劣質低價煤是降低燃煤火電廠髮電成本的主要措施之一，盤山髮電公司選擇瞭高水分、高硫分、低髮熱量的內矇古劣質褐煤進行摻燒。為瞭確保鍋爐燃燒的安全和經濟性，在劣質煤大規模摻燒之前，進行瞭劣質煤與優質煤按1：3、1：1和純褐煤3種摻配比例的磨製試驗，證明劣質褐煤摻燒技術實際應用的可行性，併對摻燒劣質褐煤的經濟性進行瞭分析，試驗數據和分析結果可供同類機組摻燒藉鑒。

One of the main measures to reduce the cost of the coal-fired power plant is burning of low-priced and lower-quality coal. The Panshan Power Generation Company chooses blended combustion of the low-quality coal of high moisture, high sulfur and low heat value from Inner Mongolia with high-quality coal in a bid to reduce the cost of generation. To ensure safety and economy of combustion in the boiler, milling tests are conducted on the pure lignite coal and other two kinds of mixed coal （low-quality coal and high quality coal blended at the ratios of 1：3 and l：l respectively） before mass blending. The test results prove the feasibility of application of the blended burning technology in the coal-fired power plant. Analysis is also made on the economical efficiency of the blended burning technology, and the test data and the analysis results can provide useful information and reference for similar generating units in blended coal burning.
