economizer

[ē′kän·ə‚miz·ər]
(engineering)
A reservoir in a continuous-flow oxygen system in which oxygen exhaled by the user is collected for recirculation in the system.
(mechanical engineering)
A forced-flow, once-through, convection-heat-transfer tube bank in which feedwater is raised in temperature on its way to the evaporating section of a steam boiler, thus lowering flue gas temperature, improving boiler efficiency, and saving fuel.

Economizer

 

a component of a boiler unit. An economizer is a heat exchanger in which feed water is heated by flue gases before the water is supplied to the boiler. For a pressure of up to 22 kilograms-force per cm2 (2.2 megapascals) and a feed-water temperature below the dew point of the flue gases or for water that has not been deaerated, an economizer consisting of plain cast-iron tubes or of finned cast-iron tubes is used. For higher temperatures and pressures, an economizer consisting of steel tubes is used; most economizers of this type consist of plain steel tubes. An economizer increases the efficiency of a boiler unit.

i. A reservoir in a continuous-flow oxygen system in which exhaled oxygen is collected for recirculation in the system. This way the consumption of oxygen is economized.
ii. The system of metering additional fuel in a carburetor or fuel injection system when the throttle is wide open. This additional fuel helps remove some of the heat when the engine is producing maximum power. The system provides an economical fuel-air mixture at all settings except at full power. Also called a power-enrichment system or a fuel economizer system.
