Thermal Screw Processor Engineering Guide

KWS Thermal Pipe 1

Thermal Pipe

KWS Thermal Screw Processors are designed to provide cooling or heating of bulk materials. Typical applications include cooling boiler ash, cooling dried biosolids and preheating powders. Heat is transferred to or from bulk materials by indirect heat transfer.

The heat transfer medium or thermal fluid never comes in direct contact with the bulk material. Thermal fluid flows through jacketed troughs, center thermal pipe, hollow flight screw, or all three depending on the thermal load requirements of the application. KWS Thermal Screw Processors provide continuous heat transfer as well as conveyance of bulk materials.

There are many advantages to using a KWS Thermal Screw Processor in your application.
