1 电站锅炉发展的要求 社会生产力的发展对电站锅炉提出了新的要求,总的说来,一是节能,二是环保。 节能问题:世界范围内普遍存在燃料价格上涨和供应短缺问题。发达国家的煤矿已开采了一、二百年,只好开采更深、更难的矿层或从海外进口,使煤价不断上涨,而石油和天燃气的价格更高。我国是煤炭开采大国,但煤炭开发的速度仍然跟不上工业发展的速度,煤炭供应将越来越紧张。因此,要求电站锅炉能更有效地利用燃料,提高发电效率。
1 requirements for the development of power plant boilers The development of social productivity on the power plant boilers made new demands, in general, first, energy conservation, and second, environmental protection. Energy-saving issues: There is a widespread worldwide problem of rising fuel prices and supply shortages. Coal mines in developed countries have been mined for one or two hundred years and had to either mine deeper or harder mines or import from overseas, causing coal prices to rise while oil and natural gas prices were higher. China is a big coal mining country, but the pace of coal development still can not keep up with the pace of industrial development, the coal supply will be more and more nervous. Therefore, power station boilers are required to use fuel more efficiently and increase power generation efficiency.
