ARL has vast range of operation therefore it needs versatility of process. This flexibility can’t be achieved without utilities operations. Utilities are the backbone of any process industry and in these utilities operations steam generation got the key importance. Steam is generated for variety of purposes. In case of refinery, steam is used mainly for stripping purpose. Other facilities of utilities operations here in ARL are instrument air, service air, plant water, soft water, drinking water, raw water, firewater, cooling water, fuel oil for plants and caustic soda plant facility.
A boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner. The boiler should also be designed to generate high quality steam for plant use. A flow diagram for a boiler house plant is presented.
