Veolia Energy reduces carbon dioxide emissions with new heat recovery system for Grand Rapids
new custom-built condensing heat exchanger for the special steam system serving the central business district of downtown Grand Rapids has reduced the facility’s carbon-dioxide emissions by 5 percent annually.
Veolia Energy Grand Rapids LLC installed the heat recovery system, called the Economizer, at the energy facility it purchased from Kent County in December 2008. Located at W. Fulton Street and Monroe Avenue, the facility provides steam to about 125 downtown commercial, government, institutional and healthcare customers to heat their buildings and their water.
