- n. One who economizes; one who uses money, material, time, etc., economically or sparingly.
- n. In engineering, an apparatus by which economy, as of fuel, is effected; specifically, one in which waste heat from a boiler or furnace is utilized for heating the feed-water.
- n. Also spelled economiser.
- n. Specifically— In fog-signaling on British railways, a device by which the detonation of one track-torpedo on the rail by the passage of the engine-wheels removes the second one in series before the wheels reach it.

Everything that I've said might make it seem like I don't, but the fact is that I LOVE Stirling engines (Though I hate calling them that, since Stirling did not invent them, but rather patented the "economizer" a device that improves their efficiency).
"economizer" to capture and recycle air that can be used as "free cooling."
I don't believe that there is a single hybrid in the senior parking lot of my kids 'high school that isn't either a pretend fuel economizer (like a Lexus GS450h or the hybrid Tahoe) or their mother's.
They designed a cooling system called an “air-side economizer” that reduces energy use through careful airflow, and water-flow design and to utilize outside air because the temperature and humidity reamin in the correct range for 75% of the year.
From the economizer the gas is drawn through a wet scrubber where it undergoes a further cooling and is cleansed of dirt and dust.
The pre-heated air and vapor leave the economizer and enter the producer through a passageway near the top and above the fuel bed.
The fuel used bears directly on the question of the advisability of an economizer installation, for when oil is the fuel a boiler efficiency of 80 per cent or over is frequently realized, an efficiency which would leave a small opportunity for a commercial gain through the addition of an economizer.
An example of its illogical use may be shown by the consideration of a boiler operated in connection with a special economizer where the vapor produced by hydrogen is partially condensed by the economizer.
The more wasteful the boiler, the greater the saving effected by the use of the economizer, and it is sometimes possible to raise the temperature of the feed water to that of high pressure steam by the installation of such an apparatus, the saving amounting in some cases to as much as 20 per cent.
Sometimes, too, the frictional resistance of the gases through an economizer make its adaptability questionable because of the draft conditions.
