The Ketema Schutte and Koerting continuous heater figure 320 is made for direct
connection to water and steam lines and has a spindle for regulating
water flow. The figure 320 heater can also be supplied
as an "instantaneous heater" with special level and cock arrangement
for producing immediate supply of hot water.
The liquid under
pressure attains a high velocity passing through the nozzle.
Steam enters through a series of nozzles in the combining tube
and an intimate mixing of the liquid and steam occurs in the
throat region. The liquid absorbs all of the heat of the steam.
Under normal conditions no loss in water pressure occurs. In
certain cases, this water can be operated against back pressures
higher than either the supply water pressure or steam pressure.
Ketema Schutte and Koerting Continuous Heaters are designed for direct connection to water and steam lines. Heaters of this type mix steam with cold water and discharge hot water under pressure. Many plants use these heaters to supply hot water for washing floors and equipment, see Fig. 320-B, below. Fig. 324 "Instantaneous Heaters" are particularly useful as warm water emergency washing units in laboratories and plant areas where safety showers are required.
These heaters can eliminate mechanical pumps, resistance or bayonet heaters and containment vessels. These units have a low initial cost, limited moving parts and are easy to install and require little or no maintenance.
