Process Flow Diagram

 EPR Waste to Energy (WTE) gasification systems can be designed and operated in a number of configurations, depending on the available feed materials.EPR modular designs include tandem fluidized be / rotary kiln reactor gasification systems that can generate between 16 and 24 MW, as well as rotary kiln only systems with oxygen reformers sized to generate from approximately 4 up to 20 MW. These latter systems can operate on a wide variety of fuels and can operate in a cogen mode wherein they generate both electrical power and a low Btu fuel gas for use as ancillary fuels in thermal power plants.

Shown below is a process diagram of an EPR system configured to operate using construction and demolition solid waste as the primary feedstock with used tires as an ancillary fuel.

Our tandem reactor gasifier systems are normally configured in modules that process approximately 500 tons per day of municipal solid waste or light C&D waste with approximately450 tons of that actually going to the gasifiers.  Approximately 16 megawatts (MW) of electrical power are produced for each 450 tons of MSW processed. Plants comprised of three or more gasifier modules with generating capacity of 48 MW or more are favored because of their economies of scale.
