Ducting system in a power plant is a conduit connecting one system to another through which either cold air or hot air or flue gas with ash is conveyed for continuous operation of the plant. To perform this function properly, careful design of ducting is required to take care of the stresses and forces exerted by various loadings and thermal expansion of the ducting and equipment it connects under given pressure and temperature. Ducting can be of any configuration viz. square, rectangular, circular, straight or bend, elbow or any other irregular shape. The design of large air and gas ducts is an extremely complex task which should meet both mechanical and structural design criteria. The purpose of ducts is to efficiently convey the air or flue gas from one location to another while maintaining the pressure drop and temperature drop as low as possible. This paper discusses about the optimization in the design engineering of the duct system.
