一、前言近年来,煤水浆技术的开发和应用在世界范围内引起广泛重视,各国在制浆和燃烧等方面做了大量工作。关于煤水浆的燃烧与气化已有许多试验进行,但是在燃烧技术中仍存在许多问题,诸如煤浆喷咀的堵塞和磨损,煤水浆着火和火焰稳定及燃烧效率低等。此外,关于煤水浆常压空气气化迄今尚
I. Introduction In recent years, the development and application of coal-water slurry technology has drawn wide attention in the world and various countries have done a great deal of work in pulping and combustion. There have been many tests on coal slurry combustion and gasification. However, there are still many problems in combustion technology such as clogging and wear of coal slurry nozzles, ignition of coal slurry, flame stabilization and low combustion efficiency. In addition, atmospheric pressure gasification of coal slurry has so far
