label: Description
content: The condenser represented in the model consists of a large vertical cylinder and pump plunger with various connected chambers designed to function as a condenser, a condenser air pump, and feed-water hot well and heater.
label: Description
content: The invention “consists in simplifying the apparatus that condenses the steam discharged by the first eduction from the cylinder of a condensing steam engine by closing the hot well of the engine against the atmosphere and by keeping a portion of the space of the hot well free from water, and by delivering the steam discharged from the cylinder by the first eduction into the hot well, so that it may be condensed or partially condensed by the water delivered by the air-pump into the hot well.” The hot well is thus made “to act also as an additional condenser and dispense altogether with an additional air pump to draw the water from the additional condenser.”
