一、前言水煤浆是一种新型的液体代油燃料,目前它已在实验室试验炉内和工业性试验炉内实现了稳定点火和燃烧。但要使水煤浆技术得到广泛的工业应用,特别是用于燃油锅炉,还存在不少技术难题,其中主要的有: 1、燃油锅炉炉膛的容积热负荷比煤粉炉高,油炉改烧水煤浆后出力一般将要降低
I. INTRODUCTION Coal water slurry is a new type of liquid oil substitute fuel and it has been steadily ignited and burned in laboratory test furnaces and industrial test furnaces. However, there are still many technical problems to make CWS widely used in industry, especially for oil-fired boilers. The major ones are as follows: 1. The volumetric heat load of the oil-fired boiler hearth is higher than that of the pulverized coal fired boilers. After the output of coal-fired slurry will generally be reduced
