Deaerator Storage Tank Level & Deaerator Pressure Control Using Soft Computing

چکیده
AbstractDeaerator is normally used in Chemical Industries, Process Industries, Power Plants and in Paper and Pulp Industries. The oxygen in the boiler feed water is the main reason of boiler corrosion. Oxygen corrosion is one of the biggest dangers of boiler. The function of the deaerator is to remove the dissolved oxygen from the boiler feed water before entering into boiler .The removal of dissolved oxygen from the water is said to be deoxidization. The deoxidization system with a nonlinear structure is characterized by multi-input multi-output and its level and pressure is strongly coupled. The pressure and level must be kept steady to get rid of oxygen in water effectively. Due to its non-linearity and strong coupling the requirements are almost unreachable when the ordinary PID control scheme is applied. Intelligent method is required.

متن کاملIntroduction of Air Cushion to Reduce Seismic Demand in Cylindrical Water Storage Tanks
Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...

متن کاملIntroducing Padded Wall to Reduce Sloshing Induced Wall Pressure in Water Storage Tanks
Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of rigid and padded wall tanks in terms of the wave elevat...
