High pressure feed water heater
A high-pressure feedwater heater is a type of heat exchanger used in steam power plants to preheat the feedwater supplied to the boiler. The feedwater heater receives high-pressure water from the turbine condenser and transfers the heat to the feedwater coming from the pump before it enters the boiler. TheRead More
Sacrificing anode in condenser
A sacrificing anode is a device that can be installed in a condenser to protect it from corrosion. Corrosion is a common problem in condensers, as the cooling water can contain dissolved oxygen and other corrosive substances that can cause damage to the condenser tubes and other components. A sacrificingRead 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
NRV IN EXTRACTION LINES
Non return valves has been installed on the non regulated extraction lines to prevent racing of TG set by reverse flow of steam at the time of tripping or shut down. These valve are force closed whenever the emergency stop valve are closed or the generator is isolated from theRead More
