THERMAL PROCESSING – THE SIMPLER THE BETTER!

Abstract

This paper introduces a simplified approach to thermal processing based on focusing on the character of the core business and concentrating on performing this core business in a reliable and cost effective way. Our designs are often influenced by the current political climate. This has led to a push for energy efficiency in the 70s and 80s and was encouraged by EPA funding. Many of the systems installed, including thermal conditioning, Carver Greenfield drying, and cogeneration systems offered great energy efficiency. Why are very few of these systems in operation today? Many plants have graveyards of failed “energy efficient” processes. This paper examines why these systems are no longer in favor and offers a procedure to keep things simpler and better.
