Flow Accelerated Corrosion (FAC) in boilers / HRSGs

Jan 01, 2015 · Abstract. Combined life cycle heat recovery steam generators (HRSG) play a vital role in energy efficiency, reducing green house effect. More than 40% of Heat recovery steam generator (HRSG) tube failures are due to Flow accelerated corrosion (FAC). FAC phenomenon occurs in carbon & low alloy steels, with poor chemical treatment & design.

Tips For A Successful Cast Iron Water Boiler Installation

Jul 16, 2018 · Simply put, leave the bypass valve open and adjust the flow through the boiler with either valve located on supply or return pipes below the bypass pipe to slow the flow and force more water through the bypass. Partially close one of these valves and check the ΔT through the boiler. You will need a minimum of a 20°F rise.

flue gas path of fire tube boiler Agent

Date: Kefid17 Author: ailsa from ZG boiler. A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. Free Chat

ALL ABOUT DELIMING COPPER TUBE *BOILERS

The flow rate of water (GPM - gallons per minute), through a boiler is critical to it's operation, performance, and life span. Temperature rise through a boiler is inversely linked to the flow rate. As the flow rate is decreased the temperature rise will increase; as the flow rate is increased the temperature rise will decrease.

Oxygenated treatment - Wikipedia

Oxygenated treatment (OT) is a technique used to reduce corrosion in a boiler and its associated feedwater system in flow-through boilers.. With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30-50 ppb. OT programs are most commonly used in supercritical (ie >3250psi) power boilers.
