High Pressure HRSG and Co-Generation Water-Steam Chemistry

Sep 29, 2015 · Boiler Water Treatment . In the 1930s as steam generator technology evolved and high-pressure units grew in numbers, tri-sodium phosphate (TSP, Na 3 PO 4) became the common chemical for boiler water treatment as it generates alkalinity (caustic, NaOH) to protect against corrosion. Also, phosphate reacts with hardness compounds to reduce the

Thermal Design of Economizer for Waste Heat Recovery

May 01, 2019 · P.Ravindra Kumar[3] One of the most cost effective ways of improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement

economizer | shipengineer

Economizers are heat exchangers which are fitted in a boiler to increase the efficiency of the boiler. This is done by extracting the heat from the exiting gas and using it to heat the feed water entering the boiler. To obtain an acceptable degree of efficiency and reduce fuel consumption as much as possible by introducing further heat recovery
