当前我国煤炭资源日趋紧张,而我国拥有比较丰富的褐煤储藏,我国褐煤储藏主要集中在内蒙及东北地区,矿区集中,储量大,大部分适宜于露天开采,因此东北地区建设大容量、高效的褐煤电站,既充分利用了褐煤资源,避免褐煤长途运输带来安全问题,大大降低发电成本,而且也促进了本地区的经济发展。为响应国家高效节能、减排环保的号召,开发燃用褐煤的超临界甚至更高参数的锅炉也就成为一种 At present, the coal resources in our country are getting tense day by day, while our country has rich lignite storage. The lignite storage in our country mainly concentrates in Inner Mongolia and Northeast China. The mining area is concentrated with large reserves and most of them are suitable for open-pit mining. Therefore, The power station not only makes full use of the resources of lignite, avoids the safety problems caused by the long-distance transportation of lignite, greatly reduces the cost of power generation, but also promotes the economic development in this area. To respond to the call of the state for energy-efficient and emission-reduction and environmental protection, the development of a supercritical and even higher-parameter boiler burning lignite also becomes a
