Abstract
An enclosed flare stack having expanded air entries for flaring waste gas. The flare stack includes an enclosure assembly having a bottom portion with expanded air entries and an upper portion through which the flared waste gas escapes. The enlarged air entries at the bottom end of the stack to reduce entry pressure loss and to increase entrained air flow when flaring waste gas. The enclosed flare stack and method of flaring waste gas also greatly reduce the height of the stack enclosure without greatly increasing the size of the flare windows.
Claims20
An enclosed flare stack having a flow path for flaring waste gas, said stack comprising:
- an enclosure assembly having a bottom portion with at least one expanded air entry and an upper portion through which said flared waste gas escapes, said expanded air entry comprising at least one upper panel having a predetermined angle with respect to said upper portion of the enclosure assembly;
- and
- a flare window adjacent to said expanded air entry of said enclosure assembly.
A method of flaring waste gas using an enclosed flare stack, said method comprising the steps of:
- flowing a waste gas through said enclosed flare stack;
- entraining air through at least one flare windows in said flare stack;
- entraining additional air through at least one expanded air entry in said flare stack, said expanded air entry comprising at least one upper panel having a predetermined angle with respect to an upper portion of said flare stack;
- and
- flaring said waste gas.
