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.

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.

The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste (30) introduced into a reactor (10), by means of a basket (18) in turn passing through an air lock (12). Plasma torches (14) burn all waste (30) contained in the basket (18). The waste is then lowered in a melting bath of a furnace (20) with an inductor (24) including a crucible-forming container (23). A combustion gas treatment train completes the facility. The furnace (20) can be dismantled, after a series of treatments of several baskets (18) of waste (30) for disassembling the crucible-forming container (23) from the furnace (20). Application in treating different radiologically contaminated and/or toxic mixed waste.

A burner assembly (100) for flaring low calorific gases, such as methane with high carbon dioxide content, may be configured to provide a gradual decrease in flow velocity. The burner assembly (100) may include a conical deflector (140) that creates a relatively large recirculation zone (154) downstream of the deflector (140), thereby to stabilize fluid flow. A swirl inducing structure positioned in a final stage of the burner assembly (100) further stabilizes the fluid flow and flame at different gas flow rates.

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.

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

The invention relates to shipbuilding and can be used in reconditioning in order to economize fuel and to increase speed. The technical problem is solved by the shipboard installation of air compressors, air receiver tanks, pass valves, air conduits, air separating conduits, air intakes and air injectors, which are interconnected by air ducts. An air separating conduit is mechanically secured in the bow of the ship and has air injectors secured along the centre thereof up to the stern. The injectors direct a jet of air backwards so that the jet of air thrusts the ship forwards, then the air rises along the sides of the ship, maintaining a layer of air between the ship and the water, thus reducing water resistance. The injectors in the bow direct a jet of air such that the ship is constantly sailing into an air space.
