ABSTRACT:
A direct contact steam injection heater allows shear to be adjusted without taking the process off-line to relieve pressure within the heater. A stud is mounted to an adjustable combining tube within the heater. The stud extends through an opening in the heater body into a sealed housing. An adjusting mechanism exerts force on the combining tube stud within the sealed housing to move the combining tube longitudinally within the body to adjust the shear within the heater. The position of the combining tube is indicated by an analog revolution counter. The adjusting mechanism can be driven manually or by a motor. The motorized embodiment of the invention can be used with feedback control to automatically optimize shear.
