Backpressure in exhaust smokestack - miuraz.co.jp

Exhaust gas generated due to combustion of the burner passes through the flue of the boiler, and is discharged to the atmospheric air from the funnel. discharges exhaust gas, however, when this draft force in the smokestack lowers, it influences the exhaust gas discharge and conducts soot accumulation.

EXERGY AND ECONOMIC ANALYSIS OF DUAL PRESSURE

Although dual pressure WHR boiler is more efficient than single pressure boiler, dual pressure boiler needs more heat transfer surface are. When the stage of boiler increases, the size of boiler also increases so it makes dual pressure more expensive. Engine load, exhaust gas temperature and fuel types, effect exhaust gas energy level, are the efficiency parameters for WHRS. In this study two-stroke
