    摘要： Disclosed is a secondary combustion structure of a smokeless stove. The secondary combustion structure includes: a stove body, a combustion disc and an inner wall arranged in the stove body, several separated first ventilation holes are provided in the combustion disc, a heating chamber is defined by the inner wall and the stove body, several second ventilation holes are provided in the inner wall, and an air inlet hole is further provided in the stove body. With the design, heated air flows out of the second ventilation holes to support combustion of combustible gas, further secondary combustion is achieved, a combustible is combusted more sufficiently, and smoke is reduced; and moreover, a top of the stove body is inclined towards the inner wall, so as to increase a flow speed of the heated gas, and increase a fire behavior of the combustible.

    摘要： A reactor system and control method. The method includes feeding solid fuel and oxygen containing gas to a first fluidized bed reactor to form a fluidized bed of particles and combusting a first portion of the fuel in the bed with the oxygen containing gas to generate hot bed particles and a first stream of hot flue gas, conveying the first stream to the flue gas channel, transferring hot bed particles including a second portion of the solid fuel at a predetermined hot particles transfer rate from the first reactor to a second fluidized bed reactor, feeding fluidizing gas to the second reactor to form a second fluidized bed, and transferring bed particles from the second reactor to the first. The method includes first and second operation modes. In the first, the fluidizing gas is oxygen containing gas and, in the second, the gas includes steam, CO2, or inert gas.

    摘要： A device to facilitate and maintain a fire, having a camera assembly with a base, an apex, lateral columns, a first ring, and a second ring; and an air intake channel connected to the camera assembly. The first and second rings are intercepted by the lateral columns to define a plurality of apertures. The camera assembly defines a cavity area. The cutouts are positioned around the base separated a predetermined distance from each other, and extend from the base bottom edge without reaching the base top edge. The main opening extends from the base bottom edge towards the base top edge. The main opening defines a semi-circle. The plurality of apertures defined at the camera assembly and air intake through the air intake channel provide a sufficient amount of oxygen so that a fire is maintained until matter upon the camera assembly is consumed without suffocating and become extinguished.

    摘要： The invention comprises: a) first comburent supplying means (18) connected to the lower part of the oxidation chamber, for introducing pressurized oxygenated gas in the oxidation chamber at a speed that comprises a tangential component; b) a particle recirculation system, which comprises: a particle separator (24) on the upper part of the oxidation chamber for trapping hot particles of ash and unburned material, and a transportation system (25) for transferring trapped particles from the particle separator (24) to the base of the oxidation chamber; and c) a gas recirculation system comprising: a sucker (26) for suctioning combustion gases from the upper part of the oxidation chamber, and pipes (27) for transferring the suctioned gases to the base of the oxidation chamber. It provides an optimized thermal transfer that reduces the emission of pollutants in waste recovery.
