最近由于燃料价格上涨,人们迫切要求建造大容量、高效率、高蒸汽参数的热电站,以节约能源。石川岛播磨公司为满足上述要求,对现有的、早在几十年前就装在国外的中小容量高参数机组进行了一次调查,并在此基础上,由该公司的研究实验机构对高蒸汽参数锅炉的基本原理进行了一些探讨和研究。通过对现有采用高压高温机组的电厂的调查,他们认为先进的蒸汽参数在将来的实际应用中可考虑采用。他们还对这些蒸汽参数和两次再热式蒸汽锅炉的某些项目进行了研究。本文论述了这些研究的结果及实验室里的研制项目,并介绍了该公司设计的蒸汽参数为316公斤/厘米~2、566℃/566℃/566℃的配100万千瓦机组的燃煤锅炉的概况。同时对该设计的经济效益、操作和运行作了概述。
Recently, due to rising fuel prices, people are urgently required to build thermal power stations with large capacity, high efficiency and high steam parameters to save energy. In order to meet the above requirements, Ishikawajima Broadcasting Company carried out a survey on the existing high and medium capacity small and medium-capacity units installed in foreign countries as early as several decades ago. On the basis of this survey, the company’s research and experimental institute The basic principles of steam boiler parameters were discussed and studied. Through the investigation of existing power plants using high-pressure and high-temperature units, they consider that advanced steam parameters should be considered in future practical applications. They also studied some of these steam parameters and two reheat steam boilers. This paper discusses the results of these studies and the laboratory’s development projects and describes the company’s coal-fired boiler with a 1 MW unit with a steam parameter of 316 kg / cm ~ 2,566 ° C / 566 ° C / 566 ° C The general situation. At the same time, the economic benefit, operation and operation of the design are summarized.
