Abstract
The article is devoted to studying the parameters of wells that are used as part of vertical landfill gas collection systems for degassing landfills. To this end, the thermophysical model developed in the first part of this work is considered. The model is constructed using the initial data obtained at real dump and landfill with subsequently comparing the calculation results with the data of experimental measurements. A method for determining the average hydrodynamic properties of wastes is proposed, using which the heterogeneity of wastes can be taken into account. The effect the operating and design parameters of the well have on its performance is investigated on the basis of these properties. It has been determined that increasing the suction pressure, drilling diameter, and perforation height allows the well production rate to be increased by around 10%. The effect the increase of the well production rate has on the landfill gas collection project’s payback period is demonstrated taking typical dump and landfill as an example.
