1. (PG60.1) All boilers having a fixed water level (steam and water interface) shall have at least one gage glass (a transparent device that permits visual determination of the water level). 2. (PG‐60.1.1) Boilers having a maximum allowable working pressure

Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam. The air surrounding the pipes is also cooler than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.

2019/1/9 · Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures. As a guideline

This lower pressure operation, combined with the shorter distance between the water/steam interface and the steam outlet pipe, further increase entrainment. Older boilers, while much larger, have a larger steam space which can tolerate greater changes in steam demand without severe changes in steam pressure or water level.

Conversely, in well-maintained steam pipes, there is significantly less air after start-up and very little water, which slows the advancement of rust. Additionally, less rust will generally form in a closed condensate recovery system than in an open recovery system due to the decreased exposure to air in the former.
