How refinery boiler works?

A refinery boiler generates steam by heating water using combustion gases from burning fossil fuels or other sources. The boiler consists of a furnace where fuel is burned, producing hot gases that transfer heat to water in the boiler tubes. This process converts the water into steam, which can then be used for various purposes in the refinery, such as driving turbines, heating processes, or providing energy for equipment. Proper control of temperature and pressure is essential for efficient and safe operation.
