Understanding particulates smooths the operations of regenerative thermal oxidizers

Regenerativer thermal oxidizers (RTOs) that control volatile organic compounds (VOCs) 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.

Mercury's Rising Impact

This contaminant, a combustion byproduct of power plants, is increasingly polluting land and water through air-borne deposition

Mercury is getting a lot of attention, both in the popular press and in state and federal regulatory agencies. Combustion systems, like coal-fired power plants, industrial boilers, incinerators, and cement kilns, are sources of mercury emissions to the air. This article outlines the mercury emission regulations that apply to different combustion systems and the best demonstrated means to control these emissions from combustion sources. This article focuses on utility and industrial combustion systems because they are the highest emitters and face the greatest reductions and tightest scrutiny.
