Description
The steam drum is the primary interface between water and steam. In a coal-fired plant, boiler feedwater passes through the economizer and into the drum where the steam separates from the feedwater and is drawn off to the superheater.Maintaining constant liquid level in the upper part of the steam drum is necessary to provide the proper quality of steam. Instrumentation must withstand high temperatures and pressures.
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.
Accessories
The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump. In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions.
