我国四个现代化的建设中,电力工业必须先行。发展电力工业,当前应本着开源节流的方针,一方面加速兴建大型现代化高效率电站,另一方面必须充分利用现有老电厂的条件,挖掘潜力,加以技术改造,使其大大降低煤耗,向现代化、高效率发展.老电厂改造在我国当前电力工业较为落后的状况下更加具有突出的意义。我国中小型老电厂为数众多,中小容量发电机组占全国电站总装机容量的四分之一左右,其总发电容量约为1200万kW,但是由于这些电站设备不仅陈旧,发电容量小,参数低,装置效率差,而且环境污染极为严重。现在全国电站装置平均热效率为27～28％,而中小型机组的发电效率都在
In the four modernizations of our country, the power industry must first go ahead. At present, the development of the power industry should speed up the construction of large-scale and modern high-efficiency power plants based on the principle of increasing revenue and reducing expenditure. On the other hand, we must make full use of the existing power plant conditions to tap the potential and make technological improvements that will greatly reduce coal consumption and modernize , Efficient development.The transformation of old power plants in China’s current backwardness of the power industry is even more prominent significance. Small and medium-sized power plants in our country are numerous, medium and small-capacity generator sets account for about one-fourth of the total installed capacity of national power stations and their total generating capacity is about 12 million kW. However, as these power plant equipment are not only obsolete but also have small generating capacity and low parameters, Installation efficiency is poor, and environmental pollution is extremely serious. Now the average power plant thermal efficiency of 27 to 28%, while the power generation efficiency of small and medium-sized units are
