Abstract
Abstract The invention is a multiple flare stack support system consisting of a base vertically extended from a horizontal surface, said base having an outer surface and an inner surface. On the outer surface of said base, two or more flare stacks are pivotably mounted in such manner that the top of the flare stack can be conveniently lowered away from the base for maintenance.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
A multiple flare stack support system useful for burning undesirable gases, comprising: A base consisting of a derrick vertically extended from an essentially horizontal support, said base having an outer surface, and Two or more flare stacks each having a top end and a bottom end, each of said flare stacks being vertically disposed along the outer surface of the base and pivotably mounted to said base or said horizontal support around a pivot point located along the bottom half of said flare stack, flexible line connected to the upper half of each flare stack, and each line passing through a top portion of said derrick over a pulley and extending toward said horizontal support, said flare stacks being mounted to the base in such manner that the top of said flare stack can be lowered to a point which is below the top half of said base by pivoting said flare stack about said pivot point in a direction away from said base.
