9/9/2003 · The steam velocity is pretty high between the boiler and the header. If you have boilers with the safety valves set for 150 PSIG, they'll normally fire to maintain a header pressure of 125 PSIG. At low loads, the boiler and head pressure will be almost the same. As the

Boiler Steam Headers | Steam header | Tpp Boilers Pvt. Ltd.

Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them. Depending on the generating capacity of the boiler the header sizes fabricated by us vary from 100 mm to

Steam Distribution System - an overview | ScienceDirect …

Steam leaving a boiler at too high a velocity entrains droplets of water, resulting in wet-steam distribution. 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 System Components | CSI Heat

Every steam system consists of the following major components: In the boiler, heat is added to liquid water to generate steam at a certain pressure. Boiler pressure is used to control the thermal capacity of the steam and to motivate the steam through the system. Steam exits the boiler through piping referred to as the steam header.
