Abstract
An improved apparatus for the combustion of hydrocarbon vapors comprising a stack; a first vapor directing assembly, a portion of which is disposed within the stack for discharging vapors below or at a first predetermined flow rate into a combustion zone at one end of the stack; a first switching valve in fluid communication with the first vapor directing assembly for directing the flow of vapors through the first vapor directing assembly; a second vapor directing assembly in fluid communication with the first vapor directing assembly, a portion of the second vapor directing assembly extending through the stack for discharging vapors above the first flow rate but below a second predetermined flow rate into the combustion zone; and a second switching valve in fluid communication with the second vapor directing assembly for directing the flow of vapors through the second vapor conducting assembly. The first and second switching valves are operably connected to a flow rate measuring device for selective flow of the vapors through the first and second vapor directing assemblies.
