It is used to control the flow of steam from the boiler to the main steam pipe and to shut off the steam completely when required. The superheater is used to increase the temperature of saturated steam without raising its pressure. SuperheaterĪ superheater is the main part of a steam-generating unit. This a device attached to the steam chest for preventing explosions due to excessive internal pressure of steam. Pressure GaugeĪ pressure gauge is used to measure the pressure of the steam inside the boiler drum. It is an important fitting, which indicates the water level inside the boiler drum to an observer. The following are the several boiler mounting and accessories used in this type of boiler: Read also: Boiler Mountings and Accessories: Types, and Their Working Boiler Mounting and Accessories of Babcock and Wilcox Boiler The dampers are operated by a chain that passes over a pulley to the front of a boiler to regulate the draught.

It transmits the steam from water tubes to the drum. It is present at the front end of the boiler and is attached to the front end of the drum. This is present at the rear end of the boiler and joins the water tubes to the rear end of the drum. It is connected by a short tube with an uptake header or riser at the back end. It is a horizontal axis drum containing water and steam. Read also: Steam Boilers: Parts, Types, Classification, Advantages, Application, and More 1.
