BOILER WATER CHEMISTRY
The main objective of feed and boiler water treatment in a power plant is to maintain the plant in a condition where it can operate reliably and efficiently. It aims:- To maintain the integrity of the feed, boiler and steam system by minimizing corrosion to an acceptable level. To maintain theRead More
STEAM ATTEMPERATION CONCEPTS
The attemperation water, which is 2-5% of the total steam flow, may come from the boiler feed water pump outlet, or further downstream, just before the economizer inlet. From an energy efficiency standpoint, attemperation would be more effective and require lower flows if sprayed further downstream. The risk of waterRead More
HEAT RATE IMPROVEMENT
Optimizing Combustion. The boiler is often a good place to begin to look for heat rate improvements. The operating conditions controlled by adjusting fuel and air flow rates among burners adjusting mixing patterns of coal and combustion air and adjusting economizer O2 level. Changes to these parameters affect quantities suchRead More
BOILER PRESSURE PARTS
In a boiler where water is converted in to the steam, which pressure is greater than atmospheric pressure termed as boiler pressure parts. Example of boiler pressure parts are Economiser Boiler drum Water walls Division panel Superheaters ( LTSH, platen & final) Reheater Attemperators All of these are working aboveRead More
