Economizer Of The Steam Boiler

Steam Boiler: Deaerator-Economizer as Feedwater Heater in

Economizer is shaped tubular heat transfer equipment used to heat boiler feed water before entering the steam drum. The term economizer is taken of the usefulness of such tools, namely to conserve fuel by taking the hot flue gas before being discharged into atmosphere. An economizer can be used to utilize the exhaust heat to preheat boiler …

QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

Industrial Boiler An important consideration regarding the use of chemi- cals in a boiler is its decomposition products. Sulfite, for example, is not recommended for use in boilers operating above 900 psig because corrosive hydrogen sulfide and sulfur dioxide are formed upon decomposition. On the other hand, HEDP and PBTC breakdown into ortho-

How Boiler Economizers Reduce Energy Consumption | Miura

Steam boilers use economizers to greatly improve efficiency as the system heats water for steam. The first economizer, patented in 1845, was used to improve the efficiency of boilers used in steam engines for mills and factories. By the 20th century, almost all steam engine boilers included economizers as a standard feature.
