Landfill Gas A Solution To Rising Natural Gas Prices Rising natural gas and fuel oil prices have users of all kinds looking for cost-effective alternatives. One viable and popular substitute is the use of landfill gas, and companies are successfully implementing landfill gas (LFG) product conversions to existing oil and/or natural gas fired boilers. Hamworthy Peabody Combustion has an extensive track record in the application and combustion of non-standard gases and recently completed two turnkey landfill gas conversion projects for a major U.S. automaker. The projects were completed within the plant outage and LFG availability schedule, and the boilers have been successfully commissioned on both LFG and natural gas. Both projects have been in service for an extended period with no operational or availability issues. The Company has just completed a third turnkey project for the same auto manufacturer. In addition to modifying an existing burner for one of the three projects, Hamworthy Peabody supplied new vertically up fired burners to burn LFG for this automaker's other two projects, as well as supplied a new PLC based burner management system, new LFG piping from LFG supplier's flange and combustion control modifications to fire landfill gas. Hamworthy Peabody's scope included the mechanical and electrical installation, as well as unit commissioning. Each of the three projects involved the application of landfill gas to an existing watertube boiler. To maximize LFG usage, the boiler combustion control system was designed so all available LFG was burned and any additional heat input required was provided by the co-firing of natural gas. In addition, the control system was fully metered to measure both air and fuel flow to assure proper and safe fuel/air ratios. During initial design and operational review with the Customer, it was noted that boiler availability was critical. As a result, Hamworthy Peabody Combustion designed this specific system to provide a constant natural gas pilot to assure stability and a constant source of flame, should there be an upset at the landfill. This constant natural gas pilot would negate the requirement for a boiler repurge should the landfill gas supply become interrupted. If the LFG supply were interrupted, the combustion control system would automatically start or increase the main natural gas burner to maintain steam production.
