Boiler feedwater economizer
WebSep 24, 2024 · Economizers are used externally to boilers for further heat recovery. Economizers are found in the cooler gas zone and are fed with water temperatures around 116 o C or 185 o C depending upon whether the feed cycle includes high pressure feed heaters after the de-aerator. Boiler With the Economizer : WebThree major parameters are considered in evaluating all boiler economizers; 1) fuel type, 2) acceptable backpressure on the exhaust, 3) inlet water temperature. These will …

WebAn Economizer recovers heat from flue gases and uses it to increase boiler feedwater temperatures, prior to entering the boiler. Cleaver-Brooks offers two types of Standard Economizers - CCE (Cylindrical) and CRE (Rectangular) units. Reduces Fuel Use and Cost: • Recovers heat from flue gases that would otherwise be wasted WebA conventional boiler would require immense initial capital expenditure on fuel usage alone per year. Therefore, slight improvement in boiler efficiency between units could provide significant amount of savings [3,10]. The preheating of feed water in boilers is one of the most effective methods for increasing the efficiency of steam boilers .
