摘要:
The present disclosure relates to a self-regulating, landfill well control system for automatically controlling a flow of landfill gas (LFG) through a wellhead associated with a landfill well at a landfill. The system has a combination unit operably associated with the wellhead, with a valve actuator, a flow measurement element and a controller. The valve actuator controls a LFG flow control valve, to thus control an LFG flow through the wellhead. The flow measurement element produces differential pressures proportional to a LFG flow rate. The controller controls the valve actuator and, based on data obtained using the flow measurement element, adjusts a setting of the LFG flow control valve to obtain a specific control point setting, and automatically maintains the control point setting thereafter.
