According to the disclosure, a compacting zone is provided, which is configured behind the combustible material feed and in front of the combustion zone in the direction of material flow (M) of the combustible material, wherein an auger of the screw conveyor and the compacting zone are preferably designed to compress the combustible material in the compacting zone.

Process and device for improving of synthesis and/or flue gas velocity field solves technical problem of local increase of velocity and resulting non-homogeneous flue gas field resulting in uneven temperature and concentration distribution within flue gas field by providing for homogenization of flue gas field using strategically placed obstacles in the flow field such as flaps or similar devices.

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.

A portable, yard waste incinerator system with a large burn tank located on a transport and configured for burning yard waste. Located inside the burn tank is lower primary combustion chamber and an upper secondary chamber, Located inside the primary burn housing with a burner. Propane fuel is connected to an external propane gas source which delivers propane to the burner. The primary burn housing includes a plurality of holes that allows flames and hot gases from the fire and heat from the primary combustion chamber to extend into a secondary combustion chamber. The system also includes a vacuum system which picks up small, loose combustible debris from the yard and delivers the debris and oxygen to the secondary combustion chamber. The system also includes an optional electric generator that energizes the vacuum system and an optional shredder that delivers shredded yard waste to the secondary burning chamber.
