烟气轮机动叶表面颗粒冷态沉积实验
Particles deposition cold state experiment on rotating blade surface of the flue gas turbine
摘要
Abstract
Flue gas turbine is the core equipment in the energy recovery system of catalytic cracking unit. In order to ensure the safe operation,it is necessary to solve the deposition problem of catalyst particles on the rotating blade surface. The influence of inlet air flow rate,concentration and particle size on the particle deposition on the rotating blade surface was studied. The results showed that the deposition quality decreases with the increase of the air flow rate. The smaller the particle size,the faster the deposition quality decreases. When the concentration is low,the deposition quality increases with the concentration increasing. While the concentration increased to a certain extent(10g/m3 under experimental conditions),the deposition quality did not vary with the concentration. In the same concentration,air flow rate and other conditions,the smaller the size of the inlet particles are,the greater the quality of deposition. Particles with size less than 40μm are more prone to deposition. Particles larger than 40μm are difficult to deposit on the blade surface. The experimental results provide a reliable basis for controlling the particle deposition.关键词
