1974年3月投入运行的中部电力公司知多电站4号机组(图1)系配70万瓩的超临界压力锅炉。本锅炉功率为70万瓩,蒸汽参数246公斤/厘米~2表压、538/538℃(汽机进口),蒸发量2350吨/时,燃用重油和原油。锅炉型式系三菱-苏尔寿-CE 复合循环(见表1)。三菱公司已设计、制造了35～60万瓩级锅炉,在本锅炉上采用了适用于大容量锅炉的新技术,下面以这些新技术为中心作概要的介绍。 Chuxudian Power Station Unit 4 (Figure 1), which was put into operation in March 1974, is equipped with a 700,000 kW supercritical pressure boiler. The boiler power 700,000 瓩, steam parameters 246 kg / cm ~ 2 gauge pressure, 538/538 ℃ (steam turbine imports), evaporation 2,350 tons / h, burning heavy oil and crude oil. The boiler type is Mitsubishi - Sulzer-CE compound cycle (see Table 1). Mitsubishi Corporation has designed and manufactured 35 ~ 600,000 瓩-class boilers, and adopted new technologies suitable for large-capacity boilers in this boiler. The following is a brief introduction of these new technologies.
