对现有的工厂进行延寿,是用最少的投资得到给定产量的最好方法,这一点对火力发电站特别合适。通过这种延寿过程可对工厂进行全面改造,对设备和工厂现代化都有好处。 这一任务的主要困难在于决策。由于实施及规划过程均有不少不确定因素,因而困难较多。本文试图提供解决这些困难的线索。 1.设备改造是一个现代的概念 世界性的投资不足,已成为新厂建设的困难,不但发达国家遇到了这一问题,发展中国家由于设备的可利用率低,且现有设备过早老化,这方面的困难更加突出。另外,设备设计的趋势是力求降低成本,而不是考虑在使用中如何延寿和提供可靠的寿命。因此,
Prolonging the life of an existing plant is the best way to obtain a given output with a minimum investment, which is particularly suitable for thermal power plants. Through this life extension process, the factory can be completely transformed, which will benefit the modernization of equipment and factories. The main difficulty of this task lies in decision-making. As there are many uncertainties in the implementation and planning process, it is more difficult. This article attempts to provide clues to solve these difficulties. 1. Equipment transformation is a modern concept. The world’s lack of investment has become a difficulty in the construction of new plants. Not only developed countries have encountered this problem, but due to the low availability of equipment in developing countries and the premature aging of existing equipment. The difficulties in this area are even more pronounced. In addition, the trend in equipment design is to reduce costs rather than considering how to extend life and provide a reliable lifetime in use. therefore,
