CPL, in partnership with Solae/Dupont, Memphis Light Gas and Water, and Allied Waste, engineered, constructed and commissioned a 5000 scfm LFGTE project in under 150 days.  CPL was responsible for both ends of project (i.e the Landfill Gas Processing (LGP) System at the landfill and the conversions of three boilers at the end user's site.

 

Project Objective:
Design, install and commission seamless transfer boiler fuel conversion system for the plant's three package boilers (combined steam outpu of xxx,xxx #/hr).  Design will allow for either stand-alone firing or co-firing of the two options for fuel (natural gas or LFG). 

• The new LFG burner section designed to fire 100% Maximum Continouous Rating (MCR) of each unit
• Boiler Controls and BMS was upgraded to Allen Bradley Control Logics Platform
• The conversions reduced NOxemissions, while burning LFG, by more than 75% over original levels
• Remote communications with landfill operations 
• Based on DOE's Average US household energy usuage of 36.3 MMBtu/yr (10,660 kw-hr/yr), this project presently, offsets the equivalent energy needed to power 31,240 homes for one year
• As of 2008, this is the largest renewable energy project for the State of Tennessee
• CPL maintains and operates the LGP system as well as performs yearly calibrations and tuning on Solae’s three boilers
• As a result of the success of this project, CPL was nominated as part of the Dupont team to receive two awards in 2005:
  1. Engineering Excellence Award and
  2. Sustainable Growth and Excellence Award.
