Physical principle behind the suction of a piston

Nov 22, 2016 · $begingroup$ There's no such thing as "suction". Rather, you're dealing with atmospheric pressure. A "suction pump" drawing water out of a well will not work if the well is deeper than about 30 feet, because that's as high as atmospheric pressure can push a column of water. $endgroup$ Hot Licks Nov 23 '16 at 3:15

Economizer - Wikipedia

The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economiser.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.
