ABSTRACT:
An improved flare stack for the smokeless burning of smoke prone fuel gases, comprising a cylindrical flare stack, an inner cylindrical conduit which is closed at its bottom end and positioned with its top at substantially the same elevation as the top of the flare stack. The flow of the smoke-prone fuel gas up the stack is diverted into the annular space between the inner conduit and the flare stack, providing an annular flow of fuel gas. Smoke suppressant, such as a mixture of steam and air, is conducted into the inner conduit and vertically upwardly to the top thereof from which it can either continue unaltered flow direction or it can be diverted outwardly and upwardly into the inner wall of the annular flow of gas, to provide quick and intimate mixing of the smoke suppressant with the fuel gas. Additionally, smoke suppressant can be injected inwardly into the outer wall of the annular flow of fuel gas, to provide additional intimate mixing of smoke suppressant, to provide smoke-free combustion of the fuel gases.
