Automated Boiler Water Cascade Tank Filling With Temperature Control

Abstract

Boilers are one of the essential machinery onboard a ships. Its purpose is to provide steam heating for the fuel bunker tanks and service tanks, heating of the sea water to produce fresh water through freshwater generator, cleaning purpose and etc. Cascade tank or hot well is a part of boiler feed water system. This tank is very important in boiler system because its a reservoir for for the fresh water that had to be supply into boiler for heating and produce steam. The important things that we need to maintain in this reservoir is the level of water and also the temperature that had to be maintained. This is because unstable water level with improperly heated feed water will cause lower boiler efficiency. This paper will focus on how to control the water level with set value with a proper temperature regulated to give optimum output for the boiler.
