Abstract

In power plant industry, boiler steam drum control is one of the most important components. This controller has responsible to supply the steam turbine continuously with high pressure and temperature steam. The controller should maintain drum pressure and water level within acceptable limits over the complete operating range [1]. The supply steam from boiler to turbine depends on water control of boiler drum. It must be accurate because of safety reason. If the level is too low, boiler tube will damage due to overheating, else if the level is too high, steam separator will not function properly, the temperature will be difficult to control and the water can full fill the turbine before extracted to the steam. So it is important to measure drum level accurately and controls the level within given ranges between high and low limits [2]. The accurate measurement of boiler drum has very influenced with production process. Measuring the level is the main point of this control, beside the method of control itself. Today, to measure a level has many instruments and methods. Such as differential pressure principle, guide wave radar, magnetic float, level gauge and many more. But in steam drum, we must be considering with the limitation of high pressure and temperature. In this paper, we will focus onto level drum measurement with differential pressure methods and direct measurement with image reconstruction of gauge glass. After that, we want to compare to find the better method can be used in boiler steam drum power plant.
