A method and apparatus, for improving the control and the efficiency of in-situ combustion (i.e. burning of oil spills atop bodies of water) of combustible waste materials on land or sea to cleanup such waste, that is also less complex than similar apparatuses, whereby the apparatus traverses over a surface containing combustible material, allowing for vortex flow incineration of the material to occur inside a combustion chamber, aided by a vortical flow of air which is controlled for greater combustion efficiency. Compared with current methods and apparatuses to cleanup similar waste, the present method requires minimal moving parts, is mobile, is low cost, is easy to construct, enables high-quality combustion, burns faster and more complete, produces low emissions, incinerates waste material on land and water, and mitigates the creation of combustion residue which thereby mitigates the adverse effects of such combustion residue that smothers ocean life.

Air Assisted Enclosed Combustion Devices (AAECD) and methods are disclosed that provide maximum destruction efficiency of VOC's and methane greenhouse gases produced by oil production, site processing, storage, and transmission operations and produces no visible emission (smoke, soot, particulates) in the process. An exemplary AAECD may include a housing with an outer housing and a burner housing separated by an air gap. The AAECD is provided with a burner assembly, a blower assembly, and a suite of sensors in communication with an electronic control module having logic configured to receive input signals from the sensors, calculate an actual fuel-air ratio using the received input signals, compare the actual fuel-air ratio to a fuel-air ratio setpoint, and adjust a position of a throttle valve to control a rate and volume of air from a blower motor to the burner if the actual fuel-air ratio and the fuel-air ratio setpoint are different.

Disclosed herein are embodiments of a flare control method and a flare apparatus for automatically controlling, in real-time, the flow of one or more of fuel, steam, and air to a flare. The disclosed embodiments advantageously allow for automated control over a wide spectrum of operating conditions, including emergency operations, and planned operations such as startup and shutdown.

Disclosed is a system and method for the combustion of biomass material employing a swirling fluidized bed combustion (SFBC) chamber, and preferably a second stage combustion carried out in a cyclone separator. In the combustion chamber, primary air is introduced from a bottom air box that fluidizes the bed material and fuel, and staged secondary air is introduced in the tangential direction and at varied vertical positions in the combustion chamber so as to cause the materials in the combustion chamber (i.e., the mixture of air and particles) to swirl. The secondary air injection can have a significant effect on the air-fuel particle flow in the combustion chamber, and more particularly strengthens the swirling flow, promotes axial recirculation, increases particle mass fluxes in the combustion chamber, and retains more fuel particles in the combustion chamber. This process increases the residence time of the particle flow. The turbulent flow of the fuel particles and air is well mixed and mostly burned in the combustion chamber, with any unburned waste and particles being directed to the cyclone separator, where such unburned waste and particles are burned completely, and flying ash is divided and collected in a container connected to the cyclone separator, while dioxin production is significantly minimized if not altogether eliminated. A Stirling engine along with cooling system and engine control box is integrated with the SFBC chamber to produce electricity from the waste combustion process. Residual heat in the flue gas may be captured after the combustion chamber and directed to a fuel feeder to first dry the biomass. System exhaust is directed to a twisted tube-based shell and tube heat exchanger (STHE) and may produce hot water for space heating.

A system and method for flaring with a flare including a flare stack and a flare tip at a well site having a wellhead and a wellbore for production of crude oil or natural gas, or both, providing produced fluid including hydrocarbon from the wellhead to the flare stack, discharging the produced fluid from the flare tip through a nozzle discharge opening, combusting the hydrocarbon of the produced fluid as discharged from the flare tip, and a control system adjusting flow area of the nozzle discharge opening.

A system and method for remote monitoring and control of landfill and recycling operations provide an intelligent centralized platform for remote, real-time industrial data gathering and process control for management of landfill and recycling operations such as leachate, gas, water and other liquids. The system and method can directly upload machine data (such as liquid volumes, flows, level, equipment runtime, sorter data, status, etc) into a centralized platform. This data can be used for analytics and automation of processes and equipment control.

An apparatus coupled to a chamber for processing extreme ultraviolet radiation includes a gas inlet configured to direct exhaust gases from the chamber into a combustion zone. The combustion zone is configured to flamelessly ignite the exhaust gases. An air inlet is configured to direct a mixture of air and a fuel into the combustion zone. A control valve is configured to change a volume of fluid exhausted from the combustion zone. A controller configured to control the control valve so as to prevent a pressure inside the combustion zone from exceeding a preset pressure value is provided.

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.
