流化床燃烧技术有两个重要的理论和技术内容,一是流态化理论与技术,二是燃烧理论与技术。从流态化角度看,组成流化床的颗粒的性质,包括密度、粒度分布、形貌特征等因素影响着流态化的质量;从燃烧角度看,粒度分布、颗粒成分、化学活性及流态化质量影响着燃烧质量。因此,颗粒自身的性质对流化床燃烧过程有着十分重要的影响。王平村煤是片状化非常严重的京西无烟煤,在流化床燃烧过程中,不仅表现出不易烧透、大颗粒严重沉积等不良现象,锅炉运行起来,还需经常放冷渣,严重时每10min就得放一次渣,运行风室风 Fluidized bed combustion technology has two important theoretical and technical content, first fluid theory and technology, and second, combustion theory and technology. From the fluidization point of view, the composition of the fluidized bed particles, including the density, particle size distribution, morphology and other factors affect the fluidization quality; from the combustion point of view, the particle size distribution, particle composition, chemical activity and flow The quality of the state affects the quality of combustion. Therefore, the nature of the particles themselves has a very important effect on the fluidized bed combustion process. Wang Pingcun coal is flaky very serious West Beijing anthracite, in the fluidized bed combustion process, not only showed difficult to burn through, serious deposition of large particles and other undesirable phenomena, the boiler up and running, often need to put slag, serious When every 10min have to put a slag, wind room run wind
