摘要
Abstract
Aiming at the phenomenon of black smoke,high exhaust temperature,serious coking of water wall and evaporation tube bundle in No.l supercharged boiler of a ship,through the analysis of the combustion principle of this type of boiler and the combustion aging of fuel oil droplets,it is found that the main problems are poor fuel atomization,incomplete combustion in the furnace and backward combustion.According to the problem orientation from the analysis of the working mechanism of boiler air distributor and fuel injector,it is found that the flame stabilizer of the fuel injector is deformed.At the same time,due to the problems of the fuel distributor and the supercharged turbine control system,the air-oil matching is not good and the air excess coefficient is small,which further affects the combustion quality in the furnace.Through the maintenance and troubleshooting of relevant components,No.1 boiler works normally.关键词
