According to the company, Engineered Concepts’ Automatic Secondary Air Control System (ASAC) can reduce fuel consumption and emissions in a wide range of natural gas-fired processing equipment by as much as 50 percent. The manufacturer states that most fire tubes consuming 500,000 BTU/Hour or more will realize a substantial emission reduction and quick payback from fuel savings.  Now available for processes with pneumatic or electrical power, ASACs can be installed prior to commissioning new equipment or be retrofit on existing equipment in the field. At one location, a large independent oil producer recently paid for the upgrade through fuel consumption savings in two months and will potentially realize over $900,000 in profit annually at today’s natural gas prices. The ASAC design (patent pending) optimizes firetube operation by monitoring and controlling the secondary air in the combustion chamber. In actual field studies, carbon dioxide emissions are reduced as much as 50 percent. The ASAC is applicable to larger process heating applications found in heaters, treaters, dehydrators and numerous other applications using a fire tube.  For more details and video explaining its operation visit www.engineeredconcepts.com.
