Wood energy systems: renewable energy application
The wood waste boiler installed at the Walker County Correctional Institute near Lafayette, Georgia, is a retrofit of an existing natural gas boiler system. The new wood fuel system uses a 150-horsepower boiler that operates at 125 psi and supplies both space heating and domestic hot water for prison use. The primary benefit of the system is the significant savings in fuel costs. Using wood waste, the estimated annual cost for fuel is $35,200, as opposed to $75,920 for the replaced natural gas system. The annual savings of more than $40,000 makes the simple payback for the $225,000 system approximately five-and-a-half years. In addition, the purchase of readily available wood waste benefits the regional economy and eliminates use of an imported fuel.
