Experimental and computational fluid dynamics simulation of performance analysis of steam generators of boilers

Poor air temperature in modern power plants is one of the main reasons for the increase in unit temperature and the deterioration of boiler performance. The main problem of the air preheater is the leakage of air on the side of the gas flue and thus lead to improper thermal performance. Thehigh ash content in Indian coal also adds to the problems associated with air tube heating. Air preheaters are designed to meet the operational requirements with consideration of the most impact parameters. heat transfer, leakage and pressure reduction. In the current work the performance of the air-conditioning heater is being tested with the help of the computational fluid dynamics (CFD)Fluent 14.0 analysis tool.
