Boiler Spare Parts Boiler Manifold Headers for Boiler Pressure Vessel
1. Descriptions:
Header is a pipe fittings for mixing working substances of boilers and ensuring uniform heating of working substances. Usually the furnace wall of industrial boilers is composed of rows of tubes(water-cooled walls), but the size of boilers is huge, and the structure is complex. It can not guarantee that the working substances in all tubes absorb the same heat. There are many differences in heat absorption in different parts. Installing headers can let the working substance in each tube converge here, and distribute to the next level of each pipe so as to reduce the thermal deviation so that the heat absorption, flow of the working fluid and cooling and thermal efficiency of the boiler are optimized and improved; in addition, the size, number and layout of the pipes in the upper, middle and lower parts of the boiler are different. The header is responsible for connecting each section to ensure smooth flow of working substances.
Boiler headers, or boiler manifolds are designed to simplify piping near the boiler, reduce installation time, labor costs and parts used. Available in various branch options with threaded inlet and outlet connections. For closed loop heating applications only.
The pressures and temperatures that headers have to withstand depend on the component to which they are connected. A header connected to an economizer or to water wall panels is subject to less severe requirements on the material than a header connected to superheaters or reheaters.
