Waste to Energy (WTE)

Luehr Filter’s Air Pollution Control (APC) technology has been successfully installed on more than 50 waste to energy facilities around the world.  These references range from highly efficient PM filter systems to multi-pollutant (PM, PM2.5, SOx, NOx, HCl, PCDD/PCDF, Hg, heavy metals) removal systems with varying sorption techniques. 
This technology has been deployed on all manner of wastes, including domestic, municipal, industrial, hospital, as well as refuse derived fuel, sludge, coal, and tire incinerators.

PM Removal
Luehr Filter’s patented support cage and flat-bag technology provides for a much smaller overall baghouse footprint.  This small footprint is particularly beneficial for retrofit and/or baghouse replacement projects at facilities with problematic space constraints. 
Luehr Filter’s flat bag technology and patented support cage also provides for exceptionally long filter life.  Filter life in the range of 6 to 10 years is often achieved even for difficult combustion processes.  This filter life provides a direct reduction for operating costs.

Sorption Technology for Multi-Pollutant Removal
The varying sorption / adsorption techniques utilized by Luehr Filter APC systems include the following:

* Exhaust gas conditioning - tempering and humidity control for optimal sorption conditions
* Highly reliable, mechanical recirculation of the additive materials with recycling rates up to 50 times through the system, resulting in reduced consumption of additives and operation at low stoichiometric ratios
* Careful selection of additive materials (calcium or sodium based) based on flue gas conditions, together with local availability of the materials
* Improved SO2 reduction with humidifying of the recycled additive materials
