Performance Improvement Study

Key Challenges

RJM was invited to review all aspects of combustion and emissions performance at this 80MWth bubbling fluidised bed generator by a financial institution seeking to optimise its investment. The plant was unable to meet its emissions limits on CO, NOx and dust at full load and was experiencing fuel blockages. Consequently, revenue was below plan.

RJM Solution

RJM introduced a series of changes to operational procedures including the re-distribution of combustion air between ports, modifications to control curves and a full CFD study to map the complex interaction between fuel particles and air jets from the secondary and tertiary air ports.

Results

Following the introduction of these various modifications, plant performance and reliability improved, with significantly reduced downtime, improved revenues and emissions compliance was restored
