Introduction

The question often arises: Why can’t one operation’s RTO operate for decades, while another cannot?
 
Regenerative thermal oxidizers (RTOs) that control volatile organic compounds emitted by a wide variety of industrial processes are widely accepted. As a general rule, RTO technology has been very successful with most installations, operating trouble-free for extended periods. In some cases, however, operation has been troublesome, and a good proportion of these
problem applications have been on biomass dryers. Biomass dryers include wood dryers, sewage sludge dryers, and dryers used in ethanol production. This paper addresses why some RTOs have problems and how to avoid these problems…
