一、序言在能源多样化进程中,随着能源燃料新的利用技术的开发,煤炭、石油等能源燃料的应用范围也在不断扩大。作为煤炭有效利用的形态,使之流体化,不仅提高经济效益,同时也降低了对石油的依赖程度。以此为目的,有 COM(油煤浆)和高浓度化直接燃烧的 CWM(水煤浆)以及以甲醇为媒液的 CMS 等。其中在日本已用于一部分大力发电厂。CWM 在输送、贮存过程中保持流动性和稳定性的同时,使之高浓度化也是开发的一个课题。而确定煤炭的粒度分布和添加剂(表面活性剂)的使用方法为其关键。
I. Preface In the process of energy diversification, with the development of new utilization technologies of energy fuels, the application range of energy fuels such as coal and petroleum is also expanding. As a form of efficient use of coal, fluidized, not only improve economic efficiency, but also reduce the dependence on oil. For this purpose, there are COM (coal oil slurry) and CWM (CWM) with high concentration and direct combustion, and CMS with methanol as the vehicle. Which in Japan has been used for some vigorously power plants. CWM in the delivery, storage process to maintain the liquidity and stability, while making it a high concentration is also a subject of development. It is critical to determine the particle size distribution of coal and the use of additives (surfactants).
