摘要： A waste heat recovery system is coupled to a flare or exhaust stack of, for example, a landfill gas treatment system, to recover at least a portion of the energy within the exhaust produced by the gas treatment system and provides the recovered energy either indirectly or directly to a secondary process, such as a wastewater treatment process, to thereby reduce the amount of energy needed to be otherwise input into the secondary process. For indirect transfer of energy the waste heat recovery system includes a transfer pipe connected between the exhaust stack of a primary process and a heat exchange unit while an induction fan connected to the transfer pipe operates to create a draft within the transfer pipe to facilitate movement of some of the exhaust gas from the exhaust stack of the primary process to the heat exchange unit. The heat exchange unit transfers energy in the diverted exhaust gas to the secondary process using for example a transfer fluid, while a secondary exhaust stack vents the exhaust gas passed through the heat exchange unit to the atmosphere. For direct transfer of energy the heat exchange unit is omitted from the waste heat recovery system and the induction fan is positioned to draw the exhaust gas from the landfill gas treatment system through the secondary process causing intimate contact of the primary system exhaust gas with a fluid within the secondary process. The exhaust from the secondary process may then be directly emitted to the atmosphere or transferred to a treatment or recovery system, as appropriate and desired.
