前言在进行锅炉制粉系统设计时,要求算出输粉管道压力损失的大小,作为选择排粉风机的依据。但根据过去有些设计计算资料计算得到的压力损失常比实际运行的数值高得多,致使设备投资及运行费用增加。为了希望能准确地计算输粉管道的阻力特性,并且使风粉分配均匀,进一步提高锅炉运行的经济性与安全性。在75年9月水电,一机部召开的六十万千瓦机组锅炉技术设计审查会上,确定进行锅炉输粉系统试验研究工作。据此,我们邀集淮南电厂、西安交大和安徽中
Preface During the design of the pulverizing system of the boiler, it is required to calculate the size of the pressure loss of the powder conveying pipe as the basis for choosing the powder discharging fan. However, the pressure loss calculated based on some design calculation data in the past is often much higher than the actual operation value, resulting in an increase in equipment investment and operating costs. In order to hopefully calculate the resistance characteristics of the powder feeding pipe and to distribute the powder evenly, the economy and safety of the boiler operation are further improved. In September 75 Hydropower, a machine department held a 600,000 kilowatts unit boiler technical review of the design, to determine the boiler feeding system test research. Accordingly, we invite Huainan Power Plant, Xi’an Jiaotong University and Anhui
