ETEC Announces Hybrid Technology to meet SCR NOx Control levels

Houston, Texas-- Entropy Technology & Environmental Consultants, Inc. (ETEC), a leading provider of innovative combustion control technologies, has introduced a very cost-effective NOx control technology that matches NOx control levels from Selective Catalytic Reduction (SCR), but for a fraction of cost. ETEC has combined proven NOx control technologies, Induced Flue Gas Recirculation (IFGR) and Combustion Modification (C-Mods), to develop a very cost-effective hybrid approach to achieve NOx levels obtained by SCR, "today's LAER technology".

Most of the NOx formed during combustion of gas and light oil is from high temperature oxidation (or “fixation”) of atmospheric nitrogen. NOx thus formed can be modeled as an exponential function of temperature and a square root function of oxygen concentration. ETEC's hybrid concept controls both these key parameters resulting in a substantial reduction in NOx. ETEC's IFGR technology (patent pending) reduces the flame temperature by recycling flue gases, resulting in NOx reduction as high as 80%. ETEC’s IFGR utilizes the existing forced draft fan to induce flue gas back into the combustion zone, eliminating the need for a separate FGR fan and windbox mixing devices that are needed for traditional FGR processes. The installed cost of IFGR in retrofit application is a fraction of the cost of low NOx burners. This makes IFGR technology the most cost-effective technology available in the market today. ETEC's IFGR technology has several advantages: minimum downtime for installation, very minor modification, relatively little or no impact on performance and operation, and, eliminates existing flame impingement problems. Unlike other combustion control systems, ETEC IFGR system improves fuel and air mixing inadequacies and in certain cases improves the energy efficiency. ETEC's IFGR designs are now being used in over 80% of working IFGR systems.

To match NOx reduction levels obtained from SCR, ETEC has combined IFGR technology with its proprietary C-Mods technology. ETEC's C-Mods technology is very similar to the proven Burners-Out-Of-Service technology and involves terminating the fuel flow to selected burners while leaving the air registers open. The remaining burners operate fuel-rich, thereby limiting oxygen availability resulting in reducing NOx formation. The limited availability of oxygen in the fuel rich region of the flame also results in a reduction of NOx emissions from the fuel-bound nitrogen. The unreacted products combine with air from the terminated-fuel burners to complete burnout before exiting the furnace. ETEC's C-Mods technology replicates the performance of LNB and Over Fire Air (OFA), but for a fraction of cost. C-Mods technology results in an incremental NOx reduction of 30 to 60%.  ETEC's IFGR and C-Mods hybrid technology results in SCR NOx levels at a fractional cost. When compared to competing NOx control technologies like SCR, ETEC's hybrid technology is expected to result in cost savings of 10 to 20 million dollars depending on the size of the unit.
