Materials recycling processes that include a combustion stage can operate very efficiently, but can produce exhaust gases that are high in carbon monoxide and the like. We describe a treatment unit which comprises a chamber for receiving the material, a heat source for (preferably) heat-treating the material and for initiating combustion, and a gas outlet from the chamber, which allows the gas that is exhausted via the outlet to be supplied to the air inlet of an associated boiler unit, with the air inlet and a separate fuel inlet feeding a burner for combusting fuel from the fuel inlet in air from the air inlet in order to heat a transfer fluid. In this way, the unburnt elements of the gas expelled from the chamber are included in the combustion process of the boiler unit and fully combusted. A corresponding method is also disclosed.

The present invention relates to a technique for treating a raw material, such as combustible waste, and more particularly to combustion, and pyrolysis and gasification treatment techniques that does not emit carbon dioxide into the atmosphere. A treatment apparatus includes a fluidized-bed furnace having a pyrolysis chamber and a combustion chamber therein, the pyrolysis chamber and the combustion chamber are separated by a partition wall, an electrolysis device configured to electrolyze water to generate hydrogen and oxygen, a methanation reactor configured to produce methane from carbon dioxide discharged from the combustion chamber and the hydrogen, a first fluidizing-gas supply line configured to supply a first fluidizing gas to the pyrolysis chamber, and a second fluidizing-gas supply line configured to introduce a second fluidizing gas to the combustion chamber, the second fluidizing gas including the oxygen and a part of the carbon dioxide.

In certain embodiments, a hydrocarbon processing site may include an internal combustion engine that, during operation, generates an exhaust gas and one or more hydrocarbon processing components that receive a process fluid, output a first portion of the process fluid via a first outlet, and output a second portion of the process fluid via a second outlet. The hydrocarbon processing site may also include a combi-flare that includes an exhaust stack of the internal combustion engine and a flare section. The exhaust stack receives the second portion of the process fluid and the exhaust gas, and the second portion of the process fluid and the exhaust gas operationally mix within the exhaust stack. Additionally, the flare section generates a flame to burn the mixture of the second portion of the process fluid and the exhaust gas.

An incineration system is adapted for burning an incineration matter, and for generating a regenerative matter by hydrolyzing a hydrolysis matter. The incineration system includes an incineration device, a boiler device, a power generating device, and a thermal hydrolysis device. The incineration device includes an incinerator that is adapted for receiving the incineration matter and for burning the incineration matter to thereby generate heated air. The boiler device receives the heated air from the incinerator and generates steam via the heated air. The power generating device receives the steam from the boiler device to generate electric power. The thermal hydrolysis device includes a tank that is adapted for receiving the hydrolysis matter and the steam. The thermal hydrolysis device is adapted for hydrolyzing the hydrolysis matter via the steam, for generating the regenerative matter by hydrolyzing the hydrolysis matter, and for outputting the regenerative matter.

The present invention discloses an industrial solid waste incinerator and flue gas treatment apparatus, comprising a water-cooled feed hopper, a water-cooled grate and a chamber which are connected in sequence. A front arch, a rear arch and side walls which are formed of membrane water-cooled walls, are provided between the water-cooled grate and the chamber, and a dechlorination tower is arranged behind the chamber. Two sets of rear secondary air pipes, which comprise an upper set of rear secondary air pipes and a lower set of rear secondary air pipes, are arranged on the rear arch, and a dry desulfurization device is arranged between the two sets of rear secondary air pipes, so that the reaction medium and the flue gas are sufficiently disturbed and mixed, and stroke is extended.
