| Abstract: | Based on the technical research of the tube wall temperature and flue gas temperature of a HG 670t/h boiler, the forming mechanism, influencing factor s and countermeasures of flue gas velocity deviation and flue gas temperature de viation in horizontal duct are systematically analyzed. It is thought that the r esidual turning at the exit of furnace is the fundamental reason for above devia tion. |
