Kellogg's, Battle Creek, Michigan
Boiler Blowdown Cooling System

Boiler blowdown water needs to be cooled at 140F before draining to sewer system. Original blowdown heat exchanger system had chronic plugging and high maintenance. Kellogg's changed to direct-injection cooling water which still caused plugging and wasted water.  ThermalTech was brought in to design and implement a non-contact heat exchanger designed for ease of maintenance and reliability.

Benefit:
The temperature of the blowdown water remains consistently within requirements and no plug-ups have occurred (more than two years run time compared to problems every few months previously!). Use of city water has been eliminated.

Type of Services:

• Design of pipe-in-pipe style heat exchanger utilizing cooling tower water in the outer pipe for the cooling medium
• RTD in the discharge with a local readout and visual alarm beacon to signal a high-temperature condition
• Directed the contracted pipefitters through the installation phase and assisted in the check-out and start-up of the system
