Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas. Based upon the value of the second net heating value, an empirical model or a non-parametric machine learning model can be selected. A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.

An incinerator comprising a cylindrical housing and a plurality of burners is provided. Each burner is oriented to emit gas at an upward and radially inward angle such that the burners collectively generate an upward, helical gas flow. A method for incinerating gas in a cylindrical housing is provided. Flowing gas through a first burner, oriented at an angle, generates an upward, helical gas flow within the cylindrical housing and draws a gas flow through a second burner.

A gas flare for burning waste gas comprises a stack with an upper chimney space, a lower combustion chamber, and a burner having one or more flame outlets positioned in the combustion chamber. A primary combustion air intake of the burner is in fluid communication with an ambient air intake to source primary combustion air therefrom. An airflow control device resides in a position operable to regulate secondary air flow from the ambient air intake to the flame outlet of the burner without obstructing the primary combustion air intake of said burner. The stack features a double hull design to preheat the ambient air as it travels to the burner, and a liquid containment/vaporization chamber is installed below the burner in heat exchange relationship with the preheated airflow path to the burner, whereby the chamber is warmed by the pre-heated combustion air and radiant heat from the combustion chamber.

The present invention relates to an incinerating system comprising an ejector system comprising an ejection nozzle and a fuel-air mixing system, a combustor, and an exhaust system, wherein the fuel-air mixing system and/or at least a portion of the combustor are oriented in a non-conventional direction/configuration, and wherein the ejector system is configured to provide required motive force in order to drive flame to continue through the burner in a desired direction.

A flare monitoring system includes a camera configured to capture one or more images of a burning portion of a hydrocarbon gas emitted from a flare stack, memory circuitry storing instructions thereon, and processing circuitry configured to execute the instructions to estimate a flow rate of the hydrocarbon gas based on first data corresponding to the one or more images, and based on second data corresponding to an internal diameter of the flare stack.

Pilot assemblies comprising a fire path tubing and pilot tubing in fluid communication through a pilot nozzle for burning waste gases in enclosed ground flares and elevated flare stacks are disclosed. A plurality of flame segments is generated using a hot surface ignition element in the fire path tubing and ignites fuel/air mixture flowing through the pilot tubing into a pilot nozzle to produce a reliable pilot flame. Methods for operating the pilot assemblies are disclosed.

Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.
