Description: Dryer Burner Upgrade to Utilize Landfill Gas and Increase Use of Renewable Energy
Dryer Burner Upgrade to Utilize Landfill Gas and Increase Use of Renewable Energy
Abstract
A landfill gas (LFG) turbine facility at the Jones Island Water Reclamation Facility (JIWRF) that produces electricity and heat for treatment processes is a major component of the Milwaukee Metropolitan Sewerage District’s (MMSD’s) overall sustainability plan. The LFG turbine facility is not always able to use all the LFG produced by the landfill due to operational constraints and maintenance cycles. In 2021 MMSD upgraded four of their twelve biosolids thermal dryers to use LFG, to increase the use of existing LFG supplies and the overall percentage of renewable energy used while reducing operating costs and greenhouse gases. Conversion of the dryers included installation of new dual fuel burners able to use either LFG or natural gas (NG) and LFG piping to connect to the existing LFG supplies. This project allows MMSD to use an estimated additional 18.6 million kWh (63,400 MMBtu) of LFG per year at JIWRF, reducing the use of NG by the same amount
