Enclosed Flares

Enclosed flares, or Vapor Combustors, are intended for high energy streams and offer economical destruction of high VOC concentrations with no visible external flame.

What is an Enclosed Flare?

An Enclosed Flare (or Vapor Combustor) is an air pollution abatement technology specially configured to handle high VOC streams. The Enclosed Flare can accommodate a high-energy process discharge stream with excess air for combustion. The heat value of the process stream is significant and can potentially provide most of the necessary temperature/energy for destruction.

How do Enclosed Flares Work?

Enclosed flares run steady-state with minimal supplemental natural gas. The energy created by destroying VOCs within the process allows for handling higher BTU-value gases. The process stream acts as fuel for the combustor, and the high-energy exhaust can feed to a boiler for reuse.

Benefits of Enclosed Flare Systems

  • No visible flame compared to traditional flares
  • Typical destruction efficiency above 99%
  • Measurable results on VOC destruction
