The retrofit of statiionary-plate type regenerative air heater for unit no.2 in Shajiao B Power Plant
as well as problems occurred in the retrofit process and measure taken have been presented. The original Rothenühle regenerative air heater has been replaced by using Ljungstrom air heater with rotating heating surface
and the steam sootblowing system being retrofitted
adding fuel gas pulsating sootblowing facility. After retrofitting
the air leakage rate of said air heater under full load has decreased from original 15.0% to 5.0%
the temperature of flue gas discharged from the boiler has decreased from original 140 ℃ to 134 ℃
