Performance Improvement and Technology Modification of Flue Gas Turbine
A low-efficiency problem existed in the flue gas turbine of the energy recovery system in the main wind turbine of a 4.5 Mt/a heavy oil catalytic cracking unit of a company.After reviewing the composition of the regenerative flue gas energy recovery system and the design parameters of the flue gas turbine,the possible causes of the problem were investigated and the target of the flue gas turbine throttling optimization was determined.A series of new technologies,such as the new high-efficiency curved and twisted composite vane type,the application of the static vane assembly of the inner and outer ring-fixed two-end support method,and the improvement of safety margins by lowering the dynamic vane height,etc.,were applied in the development of the optimization of the vane and flow path structure.After the implementation of the program,the application effect was achieved,which solved the existing technical problems,reduced the electric power consumption of the equipment,and achieved good economic benefits.
