The structure of start-up system of fuel-driven compressor is complex and prone to failure, which leads to the unit can not start, affecting the transmission capacity of natural gas pipeline. Describes the structure and start-up process of Rolls-Royce RB211 fuel-fired generating unit, describes the troubles often encountered during the start-up of the unit, analyzes the possible causes, and uses troubleshooting methods to find the problem gradually from easy to difficult and corresponding measures. Combined with the working principle of the starting system and the manual parameters, the relevant parameters of the system are adjusted according to the actual situation and the good effect is achieved. Summarize the handling measures of starting fault and put forward the operation and maintenance suggestions of the unit. It provides a reference for the analysis and troubleshooting of starting system of RB211 combustion-driven compressor.
