Enclosed Combustion Equipment and Technology

By Anu D. Vij, Ship & Shore Environmental |

A thorough understanding of enclosed combustion technologies will help engineers to select the proper equipment to balance emissions-control performance with efficiency, costs and complexity Selection of an enclosed combustion solution is a complex process that involves various environmental and operational requirements that are unique for each application. There is great benefit in selecting the correct equipment, since it can translate into decreased capital and operational costs by preventing over-designing or under-designing the equipment. Different technologies offer tradeoffs between initial cost, operating expense and complexity, emissions, fuel efficiency and destruction efficiency. This article describes the main categories of enclosed combustion devices and presents a few of the advantages and tradeoffs to aid in selecting the proper equipment for a particular case.   Enclosed flares The simplest enclosed combustion device is an enclosed flare. An enclosed flare is simply meant to hide the flame and does not make a particular effort to increase combustion efficiency or reduce emissions. Enclosed flares provide cooling and combustion air through natural draft. The enclosed flare burner is simple and can be an anti-flashback…
