Over Fired Air
Overfire air (OFA) is a technique used in utility boilers to reduce emissions of nitrogen oxides (NOx) by injecting additional air above the primary burner zone in the furnace. The additional air helps to lower the peak flame temperature and create a more uniform temperature profile, which reduces the formationRead More
Ammonia dosing in flue gas
Ammonia dosing is a water treatment process that is commonly used in flue gas desulfurization (FGD) systems in power plants. The process involves adding ammonia to the FGD wastewater, which reacts with the sulfur dioxide (SO2) in the flue gas to form ammonium sulfate. The ammonium sulfate is then removedRead More

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
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
