摘要： A pyrolysis waste-to-energy conversion system has a muffle furnace housing a rotating retort drum within the furnace and having an inlet sleeve and an outlet sleeve extending through inlet and outlet ends of the muffle furnace. A rotating retort drum drive applies rotary drive to the inlet rotating retort drum sleeves and an in-feed auger is within a tube within the inlet sleeve. An out-feed auger is within a tube within the outlet sleeve and arranged to deliver char and pyrolysis syngas to a char processing system and a syngas processing system. The inlet sleeve and said outlet sleeve are arranged to provide a gas seal to prevent air ingress or syngas egress to and from the rotating retort drum. A gas cleaning system has a cracking tower arranged to retain inlet gas at an elevated temperature for a residence time, and a gas quench and scrubber system.

摘要： A fluid flow fitting with a tubular comprising a void therethrough allowing flow of a fluid, a plurality of fins at least partially transverse to the flow of the fluid extending inward from an inner wall of the tubular, and an outlet cap having an outlet hole centered thereon. An ignition source can be placed proximate the outlet cap and/or outlet hole to ignite the combustible fluid. The fins can cause a swirling motion of the combustible fluid, thereby separating contaminants from the combustible fluid and leading to more efficient and clean combustion.

摘要： The present invention relates to a process for producing a solid biomass fuel from agricultural waste such as grass, rice husk, yam, straw, corn cob or any combination thereof, as well as a solid biomass fuel produced by said process. Additionally, the present invention relates to a combustion process comprising combusting said solid biomass fuel so as to produce energy and a pre-treatment process for pre-treating one or more sources of biomass for use in the production of a solid biomass fuel.

摘要： Embodiments are directed toward a burn bucket. The burn bucket preferably includes a body, a door moveably coupled to the body, and a lifting machine interface coupled to the body. The body preferably defines an inner burn space. The lifting machine interface is preferably configured to receive a portion of a machine that tilts the burn bucket to transition the burn bucket between a closed configuration in which the door is closed and a dumping configuration in which the door is open to facilitate dumping burnt material out of the inner burn space.

摘要： Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

摘要： 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.

摘要： The present disclosure relates to apparatuses and methods that are useful for one or more aspects of a power production plant. More particularly, the disclosure relates to combustor apparatuses and methods for a combustor adapted to utilize different fuel mixtures derived from gasification of a solid fuel. Combustion of the different fuel mixtures within the combustor can be facilitated by arranging elements of the combustor controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel mixtures.
