A regenerative thermal oxidizer (RTO) with three or more chambers. Each chamber would be in a unique mode, (inlet, outlet, purge). Each chamber has its gas flow determined by two poppet valves which define which mode the chamber will be in: inlet mode, output mode, or purge mode.

According to an embodiment, a monitoring device, comprising: a sensor for sensing inflow gas information including a component and a concentration of an inflow gas introduced into a regenerative thermal oxidizer (RTO); and a processor for determining residual gas information including a component and a concentration of a residual gas in the RTO by using the inflow gas information, and updating an inflow amount per unit time of the inflow gas according to a risk level of the RTO determined based on the residual gas information, is provided.

A flameless thermal oxidizer apparatus for a gaseous stream containing hydrogen includes a vessel containing a ceramic matrix bed; and a dip tube extending into the ceramic matrix bed, the dip tube including a first flow path for a first stream having hydrogen therein, and a second flow path for a second stream having an oxidant therein to be mixed with the first stream for introduction into the ceramic matrix bed. A related method is also provided.

A combustor having an outer stack placed around a fire tube of the combustor to direct cooler air upwards to envelop an exhaust plume from the fire tube as an air shield or curtain barrier to prevent fugitive gases coming into contact with the exhaust plume and auto-igniting.

A method for oxidizing a waste stream having hydrogen therein includes flowing the waste stream with hydrogen into an oxidant stream for mixing the streams in a proportion for providing a mixture below lower flammability limits (LFL), including the LFL of hydrogen; and introducing the mixed streams into a ceramic matrix bed of a flameless thermal oxidizer maintained at a temperature above auto-ignition temperature of the mixture. A related apparatus is also provided.

The present invention relates to a ducting system (100) for conveying a flow of a gaseous feed (110) comprising a combustible component from an inlet to at least one combustion module (12), the ducting system (100) utilising a combination of a sensor (C0) for measuring the concentration of the combustible component in the gaseous feed (110), a flame detector (F0, F1, F2, F3, . . . , Fn) a shut-off valve (6) and a flame arrestor (5) located in a flow path of the gaseous feed upstream of the shut-off valve (6) such that a measurement of a concentration of combustible material in the gaseous feed over a specified concentration by the sensor (CO) causes the shut-off valve (6) to be configured to the closed position for preventing flow of a gaseous feed comprising a combustible mixture of the combustible component from reaching an ignition source and/or detection of flame by the flame detector (F0, F1, F2, F3, . . . , Fn) causes shut-off valve (6) to be configured to the closed position for attenuating propagation of a flame towards the inlet.

A process for the elimination of thermal interferences in the infrared and video fire detection at an early stage in waste incineration plants, recycling facilities, warehouses and the like. The process is characterized by an additional noise and vibration analysis, by measuring the noise level of vehicles situated in the area to be detected or other thermal interference sources, with a distinction in measuring the noise level between day mode and night mode. The volume thresholds can thus be determined and be used as a threshold for determining whether a fire extinguishing sequence should be triggered.

The present invention provides an organic polymer waste material disposal device, which is mainly composed of a flue gas circulation system, a poor-oxygen cycle de-polymerization device, an oil-gas separation system and a waste residue collection system. The poor oxygen cycle de-polymerization device is divided into an inner chamber and an outer chamber, the flue gas circulation system sends low-temperature poor-oxygen gas to the inner chamber for de-polymerization reaction, and sends high-temperature flue gas to the outer chamber for auxiliary heating, which re-enters the flue gas circulation system; when the waste is subjected to poor-oxygen de-polymerization reaction, and has reaction in the inner chamber, the waste respectively enters the oil-gas separation system, and the waste residue collection system, thus producing the efficient separation of oil, gas and residue.
