前言炉内受热面沾污的性质和程度直接影响锅炉可用率和运行的经济性。国内过去在这方面研究的报导很少。根据电力工业科技发展规划对动力燃料炉内特性研究的要求,我所自1978年初在参考国外经验的基础上,设计和制作了飞灰烧结试验装置,初步建立了测定飞灰烧结强度的试验方法,并对一些电厂常用的41个煤种以及其中20个煤种在锅炉中燃烧产生的飞灰进行了烧结特性测定。以此对我国发电煤质沾污特性作了初步分析,同时亦是对所建立的测定飞灰烧结强度的试验方法的验证。在整个这项试验研究工作中得到了有关电厂和中试所协
Preface The nature and degree of contamination of the heating surface in the furnace directly affects the availability of the boiler and the economy of operation. There have been few reports of research in this field in China in the past. According to the requirements of the research on the characteristics of power fuel furnace in the development plan of electric power industry, we designed and produced the test device of fly ash sintering based on the reference of foreign experience since the beginning of 1978, and established the test method of determining the sintering intensity of fly ash , And measured the sintering characteristics of 41 kinds of coal commonly used in some power plants and 20 kinds of fly ash produced by burning coal in the boiler. Based on this, a preliminary analysis on the characteristics of coal contamination in power generation in our country was conducted. At the same time, it was also verified that the test method for measuring the sintering strength of fly ash was established. Throughout this pilot study has been related to the power plant and pilot
