The boilers utilize a split-header design for the outlet of the radiant superheater comprised of two 45 foot headers positioned end-to-end across the full width of the boiler. The headers are constructed from SA335 P22 (21/4 % chromium 1 % molybdenum) low alloyGet Price
The Interactions Between Steam Piping and Boiler Outlet Get Price
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.Get Price

Steam Headers. A steam header is the main steam supply pipeline, its function is to deliver steam in as high level of quality (dryness) as possible to the general areas where steam is needed. It is a distribution pipe from a steam source. From it branches laterals to individual users. You can also have a return header that collects the spent Get Price
Steam Headers and Off-takes. Shell boilers are made for capacities up to around 27000 kg/h of steam. When loads in excess of this are required, two or more boilers are connected in parallel, with an installation of four or more boilers not being uncommon. The design of the interconnecting steam header is highly important.Get Price
The steam drum pressure controller could be used to set the fuel demand before the boiler is lined up to the steam header. Figure 10 illustrates the control scheme. Figure 10: Boiler Master Overrides Share this Facebook Google+ Twitter LinkedIn Prev Next Get Price

9/9/2003 · 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. New headers are often oversized initially anyway, to allow for future additions.Get Price
