Steam Distribution System - an overview |

Recommended velocities are: steam exit from boiler, 12 m/s; exhaust steam, 18−23 m/s; dry saturated steam, 23 −30 m/s; superheated steam 36−48 m/s. Steam should be generated at the highest pressure required by any consumer, plus an addition for pressure drop in the pipeline to the consumer.

Piping for Steam Distribution | PIPING GUIDE

2020-2-28 · Steam is widely used in most of the process industry as process heating media and in all power generation plants. Handling of steam is becoming very important. To study and understand the property of stem, condensate and it's effect on the material of construction is again important while designing the piping system for steam distribution.

2003-9-9 · As the load increases though, the boiler pressure rises - it has to to put more steam through the same size steam lead. At high fire, the boiler drum pressure might be 140 or 145 PSIG. The header pressure should be a constant 125. There's no way you can (or should) have the velocity of steam in the header the same as the steam leads.

3. STEAM SYSTEM

2017-9-8 · As steam condenses in a process, flow is induced in the supply pipe. Condensate has a very small volume compared to the steam, and this causes a pressure drop, which causes the steam to flow through the pipes. The steam generated in the boiler must be conveyed through pipework to the point where its heat energy is required.
