Afterburner For incineration applications, afterburners are installed on multiple hearth furnaces directly after the incinerator and before any additional air pollution control equipment. Typical afterburner designs include a top hearth, a top hearth with jumper flue, and an external chamber. Some state regulations provide a minimum temperature that the afterburner is to be maintained above when in operation.
Chavond-Barry Engineering Corporation has worked with our clients to correct afterburner design flaws that cause the inability to reach the desired temperatures and permitted operation requirements. We performed a detailed evaluation to correct the problem, and by increasing burner capacities on the incinerator and adding acid gas control to the scrubber we were able to correct the design issues and meet the permitted requirements. |
RTO Regenerative Thermal Oxidizer (RTO) is a reheat and oxide process that is an alternative to an afterburner. It is used to recover heat from exiting exhaust gasses and only requires a single burner. The benefits of this design is that it is more efficient than traditional afterburners by using waste heat recovery rather than fuel and reduces potential NOx production.
CBE has experience in designing, specifying, and integrating a RTO for a multiple hearth incinerator system. Our design expertise includes providing versatility for a plant desiring an installation of a single RTO as independent system capable of operating with either of the plant’s incinerators along with keeping the option to use the existing afterburners on both furnaces. |
