PROCESS AND APPARATUS FOR THE SELECTIVE PRODUCTION OF HOT WATER AND STEAM

摘要

A process and apparatus is provided for the selective production of hot water and steam from a constantly operating heater and with the use of a water pump intermittently feeding a constant volume of water through a conduit toward the heater, the pump and the heater being operable at a first rate of pumping frequency and at a first level of temperature for the production of hot water at a first operating condition. A control arrangement is provided for establishing a second rate of pumping frequency at the pump less than the first rate and a second level of temperature at the heater greater than the first level for the production of steam at a second operating condition. Control switches permit switching from one operating condition to another, and a steam collector used in the production of the steam includes an actuator for the switches so that the operating conditions are switched from one to the other upon insertion of the steam collector into and removal from a support for the collector beneath an exit opening of the conduit.
