Waste Heat Landfill Gas Generator(ST9173)

Auburn City of


The City of Auburn will team up with the New York Power Authority (NYPA) to implement this project. NYPA will provide system design and will issue competitive bids for equipment procurement and installation. Upon completion of the installation, the CHP system will be piped to the incinerator and used as the primary incinerator fuel. Natural gas is available as a backup fuel. The incinerator's exhaust gas stack temperature is approximately 1,600 Deg. F., which is owned and operated by the City of Auburn. The Auburn wastewater treatment facility incinerates its wastewater treatment sludge to reduce moisture and destroy pathogens. Landfill gas (LFG) from a nearby landfill has an opportunity for waste heat utilization. The incinerator layout and remote location make the site very attractive for a CHP project. Based on a review of site data for gas usage, and exhaust gas flow and temperature, it was determined that sufficient waste heat is available to generate approximately 1.4 MW of electricity.

Project Description

The City of Auburn will install a 2 Megawatt Landfill Gas (LFG) to Electric Generation Facility and Combined Waste Heat system at the City of Auburn (Auburn) municipal Wastewater Treatment Plant, in Auburn, NY. The project will utilize 700 to 800 CFM of landfill gas from the Auburn landfill to generate electricity to power the Wastewater Treatment Plant site and export excess power to NYSEG’s utility grid. The LFG to Electric Generation Facility will consist of a landfill gas conditioning and delivery system feeding two GE Jenbacher engines. Each GE Jenbacher JMS 320 engine is rated at 1,057 kW_electric, 4,160 volts, 3-phase, 1.0 PF, with a total thermal output of 1,308 kW (4.5 MMBtu/h). Each engine’s high temperature liquid and exhaust streams will be fed to a dedicated Kickham Vaporphase model ECXWV 3890-2.0 heat recovery boiler. The boiler will heat 145 gpm of 194°F water to 228°F with the exhaust waste heat. In addition, each engine also provides a separate 110 gpm low temperature liquid output at 146°F. The total power generation capacity of this facility is estimated to be 2.1 MW electric and approximately 9.0 MMBtu/h thermal. Assuming an operational availability of 95% (8,322 operational hours per year), this facility is anticipated to generate approximately 17.5 MWh of electricity and 70 billion Btu of thermal energy annually over the 15-year LFG supply.
