Environmental Compliance – Coal Boiler to Biomass Firing Boiler System

Owner:  Detroit Edison Energy Systems (DTEES)DTE Stoneman picture

Project Location:  Cassville, Wisconsin

Project Completion:  June 2010

Project Description:

 ESI was selected to provide complete engineering for conversion of the two existing 27 MW pulverized coal-fired utility boilers at the DTEES owned Cassville facility to a biomass fired boiler system.  This included the retrofit of two (2) identical 1950 vintage Riley wall-fired coal boilers to stoker fired biomass units with a total capacity of 47 MW.

This conversion included replacement of the entire backend of the boiler island, including new selective non-catalytic reduction and electrostatic precipitator.
