九、动力煤推行按热值计价动力煤主要包括工业锅炉和工业窑炉等使用的煤炭,如发电用煤、水泥陶瓷用煤、蒸汽机车和蒸汽锅炉用煤等。我国一直沿用苏联的办法,以灰分高低为主要质量指标对煤炭标定价格。通过长期工作实践,各方面认识到这种计价办法有明显的缺陷。参考一些经济发达国家的做法,经国务院批准,国家物价局,煤炭部于1986年底下发《动力煤按发热量计价的试行办法》,1987年底对这个办法进行了修订,颁布试行,在我国推行动力煤按热值计价。 9. Thermal Coal Price Promotion Thermal coal mainly includes coal used in industrial boilers and industrial kilns, such as coal for power generation, coal for cement ceramics, coal for steam locomotives and steam boilers. Our country has always followed the Soviet approach and used the ash content as the main quality indicator to calibrate the price of coal. Through long-term working practices, all parties recognize that there are obvious flaws in this valuation method. With reference to the practices of some economically developed countries, with the approval of the State Council, the State Price Bureau and the Ministry of Coal Industry issued the Trial Measures for Calculating Thermal Coal by Calorie at the end of 1986 and revised this measure at the end of 1987, promulgating and piloting it in our country Thermal coal price by calorific value.
