Shell type oil steam generator is a kind of water tube boiler, which is mainly composed of furnace, water wall, economizer, superheater and steam drum. It is an efficient and energy-saving equipment for generating steam, which can be used in various industries such as food, chemical, pharmaceutical, textile and other industries. In order to ensure the safe and efficient operation of the shell type oil steam generator, it is necessary to understand its structure and working principle.

The shell type oil steam generator is mainly composed of a furnace, water wall, economizer, superheater, steam drum and other components. The furnace is the heat source of the boiler, and the fuel is burned in the furnace to release heat energy. The heat energy is transferred to the water wall through the furnace wall, and the water wall is heated to generate steam. The economizer is used to recover the heat of the flue gas, which can improve the thermal efficiency of the boiler and reduce the exhaust temperature. The superheater is used to further heat the steam and increase the temperature of the steam, so as to meet the requirements of the process. The steam drum is used to separate the steam and water, and the water is returned to the boiler for re-heating.

The working principle of the shell type oil steam generator is based on the principle of heat transfer. The fuel is burned in the furnace to release heat energy, and the heat energy is transferred to the water wall. The water wall is heated to generate steam, and the steam is separated from the water in the steam drum. The steam is then sent to the superheater for further heating, and then to the process for use. The flue gas generated by the combustion of the fuel is discharged from the chimney after being cooled by the economizer.

In order to ensure the safe and efficient operation of the shell type oil steam generator, it is necessary to understand its structure and working principle, and pay attention to the inspection and maintenance of the boiler. The boiler should be inspected regularly to check for damage, leakage or other abnormalities. In addition, the boiler should be operated according to the instructions, and the operating parameters should be adjusted and controlled in time to ensure the safe and efficient operation of the boiler.
