The construction of the vertical steam generating bank is similar to the vertical economizer, which based on experience is very easy to keep clean.
32.
To minimize the risk for plugging and maximize the efficiency of cleaning both the generating bank and the economizers are arranged on generous side spacing.

The note itself was not just placed in the article at all; it was added on 12 September last year by User : Economizer.

By 1884 they were building all sizes of " Steam Engines and Boilers " and specialized in " Economizer " which was a portable model.
35.
The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.
36.
Sometimes an economizer circuit is also installed to reduce the power required to keep a contactor closed; an auxiliary contact reduces coil current after the contactor closes.
37.
Economizers lower stack temperatures which may cause condensation of acidic combustion gases and serious equipment corrosion damage if care is not taken in their design and material selection.
38.
The economizer concept is linked to subcooling as the liquid line in that system is around or even higher ( it varies depending on the condensing temperature ).
39.
Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design.
40.
A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases ( flue gas ) and transfer it to the boiler feedwater.
