Learn the basics of HRSG inspection - Welcome To . Learn the basics of HRSG inspection. Debris volume, if large, suggests possible rethinking of blowdown pro­cedures and/or the need to check for iron transport caused by FAC. Fig 54 is a photo of iron debris found in a stagnant area of an HP drum at an end beyond the baffle.

HRSG - Heat Recovery Steam Generators | Cai

The blowdown sequence occurs while the engine is in full operation and is fully adjustable. The special flood-jet type nozzles achieve maximum cleaning velocity using steam or air as discharged through an electric control valve (included). Together they form a "continuous knife edge concentrated spray pattern" surrounding the heating surface.

Kings Mountain Energy Center - HRSG Blowdow

A new HRSG system required 3 industrial pump stations to provide water for its processes. This HRSG blowdown pump station needed to handle extreme pumping conditions. The pumps were engineered outside the wet well in a vertical configuration to prevent damage from exposure to hot, caustic water created in the HRSG blowdown process.

Steam Calculators: Boiler Calculat

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Boiler Blowdown Cooling - Power Industry

Boiler Blowdown Cooling - posted in Power Industry: Dear Sir, In power plants, boiler blowdown is cooled by quenching with water before sending to ETP/Central Monitoring basin. This quenching water requirement increases the consumption of water. Is there any other alternative to cool the blowdown water other than quenching or cooling across heat exchangers.
