20世纪70年代，市场对经济的燃油替代产品产生了需求。然而在目前的环境下。由于油价下跌和石油供应过剩，这些潜在的替代产品大多不经济。然而，有一个显著的例外——水煤燃料（CWF）——已经取得了商业地位。本文概述了一家主要CWF供应商实施的五年发展计划。技术发展包括确定煤炭和化学添加剂特性与理想CWF特性之间的关系。 工艺放大现已达到20吨/小时（5000加仑/小时）的水平。为CWF开发了专门设计的燃烧器，这些燃烧器也能与燃油一起运行。介绍了一台工业锅炉由6号燃油改为水煤浆的改造情况和运行结果，以说明水煤浆的商业适用性。最后，总结了与将锅炉改为CWF燃烧相关的经济考虑。单位:I-PCITION:研讨会，ASHRAE交易，1986年，第92卷，pt。1B，旧金山

In the 1970s a market demand developed for an economical fuel oil replacement product. However in the current environment. of declining oil prices and excess oil supplies, most of these potential replacement products are uneconomical. Nevertheless there is one notable exception -- coal-water fuel (CWF) -- that has achieved commercial status.This paper includes a summary of the five-year development program conducted by one of the major CWF suppliers. Technology development included determining the relationships between the coal and chemical additive properties and the desirable CWF characteristics. Process scale-up has now reached the 20 ton/hour (5000 gallons/hour) level. Specially designed burners have been developed for CWF that are also capable of operation with fuel oil.The conversion of an industrial boiler from No. 6 oil firing to CWF firing and the operating results are presented as an example of the commercial applicability of CWF. Finally, a summary is presented of the economic considerations related to a decision to convert a boiler to CWF firing.Units: I-P
