Overview of EPA's (Environmental Protection Agency's) program for retrofit sorbent-injection technologies

Technical Report ·
OSTI ID:6613304
An overview is given of EPA's research program to develop improved control technologies for emissions of sulfur dioxide (SO/sub 2/) and nitrogen oxides (NOx) from the combustion of fossil fuels. Analysis indicates that low-capital-cost technology for retrofit to existing boilers would provide flexibility in control strategy even at moderate (e.g., 50%) SO/sub 2/ removal rates. EPA is evaluating the Limestone Injection Multistage Burner (LIMB), which combines sorbent injection for SO/sub 2/ control with the use of low-NOx burners. EPA also is evaluating E-SOx and ADVACATE (ADVAnced SiliCATE) technologies. E-SOx combines advanced electrostatic precipitator (ESP) technology and spray-dryer technology to remove particulate matter and SO/sub 2/ in the same physical equipment; the ADVACATE process uses in-duct injection of a highly reactive calcium sorbent for SO/sub 2/ control. The process may be used alone or in combination with LIMB to enhance performance. EPA's program for research and development, field evaluation, and demonstration of LIMB, E-SOx, and ADVACATE technologies is described.
