Description
TITLE OF THE INVENTION:
Apparatus for burning off unprocessed gas NAME ( S ) OF INVENTOR ( S ) David Stevens FIELD OF THE INVENTION
The present invention relates to an apparatus for burning off unprocessed gas.
BACKGROUND OF THE INVENTION
In the oil industry, many wells produce combustible waste gases. These gases must be disposed of in a safe manner. It is unacceptable to vent such gases to atmosphere, as they present a hazard to the environmental and public health. The gases also have the potential to create an explosive mixture with air.
When there is a continuing need for a waste gas burner, a permanent installation is installed. Permanent installations are expensive and are not readily moved from site to site.
Where there is a one-time or occasional need for a waste gas burner it is necessary to use a portable waste gas burning system.
One type of portable waste gas burning systems is a portable flare. The combustible waste gases are vented via a burner unit at which the gases are burned before being vented to the atmosphere. Flares can be at any height above the ground, but usually comprise a vertical tubular conduit, or "stack" , at a remote end of which the burner is placed. Flares can be mobile for movement from site to site. A mobile flare system must be dismantled or the stack must be lowered before the mobile flare can be relocated. One such system with a stack that can be pivotally moved to a travelling position is described in U.S. Patent 5,429,496, by Stephens and Duke.

an open flame burner positioned within the combustion chamber at the first end of the body, the burner being adapted to ignite a mixture of unprocessed gases and combustion air as the unprocessed gases fed through the vapour feed conduit mix with combustion air fed through the air inlet;
a fuel feed conduit supplying fuel to the burner;
a control valve on the fuel feed conduit adapted to control the supply of fuel to the burner;
an exhaust outlet in fluid communication with the combustion chamber and extending through the top at the second end of the body;
an electronic temperature sensor positioned within the exhaust outlet;
an electronic control unit in communication with the temperature sensor in the exhaust outlet and the control valve of the fuel feed conduit supplying fuel to the burner, the electronic control unit being adapted to regulate the supply of fuel to the burner so as to maintain exhaust gases flowing from the exhaust outlet at a selected temperature.
16. The apparatus as defined in Claim 15, wherein the vapour feed conduit includes a tubular distributor ring that encircles the burner.
17. The apparatus as defined in Claim 15 wherein the exhaust outlet has a spark arrestor.
18. The apparatus as defined in claim 1, wherein the exhaust outlet has a tubular exhaust stack.
19. The apparatus as defined in Claim 18, wherein the exhaust stack is pivotally mounted to the exhaust outlet for movement between a vertically extending an operating position and a transport position.
20. The apparatus as defined in Claim 19, wherein a support is provided to support the exhaust stack in the transport position.
21. The apparatus as defined in claim 15, wherein a damper is provided in the exhaust outlet.
22. The apparatus as defined in Claim 15, wherein the combustion chamber is lined with a refractory material.
