A thermal oxidizer employing an oxidation mixer, an oxidation chamber, a retention chamber and a heat dissipater forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream, the oxidation chamber facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream, the retention chamber facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases and the heat dissipator reduces the temperature of the flow of oxidized gases within the heat dissipator, which is communicated to a greenhouse gas processor that extracts greenhouse gas(es) from the vaporized oxidized gases. The greenhouse gas processor may condensate the greenhouse gas(es), acid neutralize the condensation of the greenhouse gas(es), and capture the acid neutralization of the condensation of the greenhouse gas(es).

A method and an apparatus for treating comminuted waste material the method comprising: •a) heating comminuted waste material in a heating chamber (28) using one or more heating means (40a-f) to generate a combustible gas •b) measuring or determining the temperature in the heating chamber; •c) comparing the measured or determined temperature in the heating chamber ((28) with a predetermined temperature range; and •d) adjusting the amount of heat applied by the one or more heating means (40a-f) to the heating chamber (28) to maintain the temperature in the heating chamber within the predetermined temperature range.

A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing process tool, the radiant burner comprises: a sintered metal fibre sleeve through which combustion materials pass for combustion proximate to an inner combustion surface of the sintered metal fibre sleeve; and an insulating sleeve surrounding the sintered metal to fibre sleeve and through which the combustion materials pass. In this way, a radiant burner is provided which does not crack due to rapid cycling caused by frequent idle steps during which the burner is extinguished. Also, by providing an insulating sleeve, the temperature within the radiant burner and the temperature of an outer surface of the radiant burner remain comparable with existing ceramic burners. This enables the radiant burner to be substituted in place of existing ceramic burners as a line-replaceable unit which does not suffer from cracking during such frequent and short-duration periods of process tool inactivity.

A remote sensing system which may be assembled with an Infrared (IR) sensor, or a plurality of IR sensors, disposed to sense IR radiance emitted as combustion products from a flare stack in two distinctive spectral bands, each band having a narrow spectral bandpass, the sensor being radiometrically calibrated to sense transmission characteristics of the two distinctive bands of the radiance from flare combustion gases; and an analyzer driven by a microcontroller, coupled to the IR sensor, to operationally respond in real time by generating an indication of flare stack's performance through a parameter derived from a ratio of the transmission characteristics of the two radiance outputs sensed by the IR sensor. The IR sensor of this flare monitoring-apparatus must be positioned in such a way that the anticipated entire flame will be captured within the Field of View (FoV) of the IR sensor, or sensors.

A grilling device includes an auger feeder system, a heating element, a blower and a temperature control system. The temperature control system includes at least a first temperature sensor inside the firepot and a second temperature sensor inside a cooking chamber above the firepot. The heating element can also serve as the first temperature sensor. A method for controlling the temperature of the grill can include receiving temperature feedback information from one or more of the temperature sensors and adjusting power provided to the auger feeder system, heating element, and blower. The temperature control system produces cold smoke resulting from the combustion of lignin in solid wood fuel while minimizing temperatures inside the cooking chamber.

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.

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.

Disclosed is an outdoor cooking appliance with a control mechanism for controlling a heating system to provide heat to a cooking chamber of the appliance within a more precise range in temperature. For example, fuel provided to a burn pot for combustion to reach a range of a target temperature of the cooking chamber. A heating element provides additional heat to bring the temperature of the cooking chamber closer to the target temperature.
