Hot-well.
A compartment in the cistern in which the condenser and air-pump of a condensingengine are submerged, and from which the warm water is drawn for the supply of the boiler. The submerged injection-chamber and the airpump connect by a passage, whose valve opens during the ascent of the piston and closes during its descent. The uncondensed steam, the air, and the water of condensation pass by this passage to the airpump, through the bucket of the latter as it descends, and are ejected into the hot-well. the heated water is drawn thence to supply the boiler. See airpump; Cornish steamengine.Houguette. |
