Steam and Water Circulation Mud drum and collector headers simple steam drum Power Station


Product Description


The word "header" is used in boiler technology for all collector and distributor pipes, including the mud drum.The most important design parameter for headers is diameter. It is defined by the flow rate and the number of tubes connected to the header (here the number of riser tubes).


Construction


Header construction is basically a miniature version of a simple steam drum (diameters are smaller than the ones of steam drums). However, in headers there are usually no internals except the orifices in forced circulation and once-through principle boilers. Small diameter headers are constructed from a tube with welded front and end plates, whereas the big headers are made of bent steel plates in the same way as steam drums.
