Power Plant Boiler Steam/Water Drum for Industrial Boiler High Efficiency




The boiler headers have water wall header, superheater header,economizer header and so on, it acts as collection, mixture, re-distributing working medium, as the structure, it can be classified as the end cover type( end enclosure) and necking down type.

The header is consisted of header body ( large diameter seamless steel tube ), end cover ( enclosure ) , tube joint, hand hole, thermomter socket and so on. And the welding checking is strictly proceeded as the welding process to guarantee 100% qualified products.


Drum is a cylindrical pressure vessel used for steam water separation and steam purification in water tube boiler to form water circulation circuit and store boiler water. Its main function is to receive water from economizer, separate steam and water, supply water to circulating circuit and deliver saturated steam to superheater. There is a certain amount of water in the drum, which has a certain amount of heat and working medium storage. It can slow down the steam pressure change speed when the working condition changes, and play a certain buffer role when the feed water and load are not coordinated for a short time. The drum is equipped with internal devices for steam water separation, steam cleaning, dosing in the boiler and continuous blowdown to ensure steam quality, as shown in the figure.


Drum is the most bulky and expensive thick wall pressure bearing part in boiler. The drum not only bears high internal pressure, but also generates thermal stress due to the variation of operating conditions and the fluctuation of wall temperature. Therefore, the working conditions are poor, and effective monitoring of operating conditions is needed.



Steam-water separation details

Primary steam-water separation removes nearly all the steam from the water so that very little steam is recirculated from the drum bottom towards the heated tubes through the outlet connection (downcomer).

At secondary separation, steam is passed through a secondary stage of separators or scrubber elements (usually closely spaced corrugated parallel plates) for final water droplet removal. Steam is then exhausted through various ports.
