Investigation of Pıpe Failures in Thermal Power Plants

Abstract

Power Plants have a big importance for transforming
fossil resources existing in our country into electrical energy since using
electricity in the world is increasing continuously. For total production of
electricity, with lignite ones are more important than other power plants. One
of the biggest defect cutting off production of electricity is boiler tubes
failures. In this study, reasons of the tubes failures which cause energy
interruption had been researched. Furthermore, for Seyitömer Power Plant, cost
of this issue had been calculated. Boiler tubes failures which cause big
production lost and negative effect of central life are happened due to
corrosion occurred by oxygen, hydrogen damage, acid aggression, tension crack,
interior pollution, over heating with short and long time period, and mechanic
erosion. This problems make double cost a current issue. Both changing tubes
costs and lost energy costs problems are seen on the changing time. The main
reasons of tubes failures at Seyitömer Power Plant are corrosion occurred by
ash, high heat, welding mistakes, and interior pollution. The biggest reason of
the corrosion occurred by ash is that coal used at this central has high ash
ratio.
