Can you really control a one-pipe steam system?

Boiler Facts by George Carey I was recently called to come look at an interesting steam problem from a local service manager. His company had replaced a steam boiler over the summer for one of their customers. The building was a large apartment building with a one-pipe steam system. While they were going through the apartments, counting the

Pipe Sizing Steam Supply and Condensate Return Lines

Two principal factors determine pipe sizing in a steam system: 1.The initial pressure at the boiler and the allowable pres-sure drop of the total system.The total pressure drop in the system should not exceed 20% of the total maximum pressure at the boiler.This includes all drops— line loss, elbows, valves, etc. Remember, pressure drops are a

Any non-insulated parts of the NPS 3 pipe would lose 50% more heat than the NPS 2 pipe, due to the extra Heat Transfer surface area. Undersized pipework means: A lower pressure may only be available at the point of use. This may hinder equipment performance due to only lower pressure steam being available. There is a risk of steam starvation.

Introduction to Steam Distribution | Spirax Sarco

A kilogram of steam at a higher pressure occupies less volume than at a lower pressure. It follows that, if steam is generated in the boiler at a high pressure and also distributed at a high pressure, the size of the distribution mains will be smaller than that for a low-pressure system for the same heat load. Figure 10.1.2 illustrates this point.

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Steam Distribution System - an overview | ScienceDirect Topics

8.1.4 Steam distribution system. The steam distribution system transports the steam to the consumers. The pressure in the steam distribution system is usually between 2 and 12 bar, where steam with a pressure of between 2 and 5 bar is called low-pressure steam, and medium-pressure steam has a pressure of between 9 and 12 bar ( SFI, 1990 ).
