一、质量要求随着煤炭采选和燃烧技术的不断提高,以及各国普遍对燃煤释放二氧化硫造成大气污染的高度重视,对煤炭质量的要求呈现出了“高严”(必须达到标准)、“稳定”、“方便”(不需加工就能直接投入使用)。如日本电力界就明言:“不仅在供电方面负有非常重大的责任,而且对环境保护方面也负有非常严峻的义务。”要点是:1.重视和欢迎洗煤进口和逐步减少原煤进口量。主要是煤炭经过洗选加工后,既能提高燃料效率;又减少锅炉及辅助设备的磨损,提高设备利用率;电能的消耗和减少停机事故并可
First, the quality requirements With the continuous improvement of coal mining and combustion technology, and the widespread concern of countries in the air pollution caused by the release of sulfur dioxide from coal combustion, the requirements for coal quality have shown a “high and strict” (must meet the standard), “ ”Stable“ and ”convenient" (it can be put into use without processing). For example, the Japanese electric power industry has stated clearly: “Not only does it have a very important responsibility in terms of power supply, but it also has a very serious obligation to protect the environment.” The main points are: 1. Pay attention to and welcome the import of coal washing and gradually reduce the import volume of raw coal. Mainly after coal washing and processing, it can not only improve the fuel efficiency, but also reduce the wear of boilers and auxiliary equipment, improve the utilization of equipment; the consumption of electric energy and the reduction of downtime can be
