为了更快地发展电力工业,缩短火电站的建造周期具有重大的意义。近年来火电站建设的趋向依旧是单机功率和电站功率的不断增长。目前世界各国都致力于兴建大功率火电站(100～250万瓩,甚至更大)。燃天然气、重油和廉价煤的电站日益增多。在这种情况下,建造露天或半露天电站以缩短建造周期和降低造价就成为电站建设的重要问题之一。对于锅炉机组来讲,由于提高了运行可靠性,延长了两次检修期间的运行时间,以及自动化程度的提高,使电站运行人员的数量大为减少,设备的
In order to develop the power industry faster, it is of great significance to shorten the construction period of thermal power plants. In recent years, the trend of thermal power station construction is still stand-alone power and power station power continues to grow. At present, all countries in the world are devoting themselves to the construction of high-power thermal power plants (100-250 million tons or more). Power plants that burn natural gas, heavy oil and cheap coal are increasing. In this case, the construction of open-air or semi-open-air power plant to shorten the construction cycle and reduce the cost has become an important issue of power plant construction. For the boiler unit, due to increased operational reliability, extended maintenance time during the two maintenance, as well as the degree of automation, so that the number of power plant operations greatly reduced the number of equipment
