摘要： A method of firing a biofuel is provided. The method includes: introducing the biofuel into a combustion chamber having a first stage and a second stage; combusting the biofuel in a suspended state while flowing from the first stage to the second stage; and introducing a first air stream and a second air stream into the combustion chamber at the first stage and at the second stage, respectively, to facilitate combustion of the biofuel.

摘要： A cylindrical furnace having a vertical axis controls combustion. Solid fuel, particulates, and gases inside the furnace rotate around the axis, inducing radial stratification using centrifugal forces. Fuel and particulates drag on the wall of the cylinder, slipping in and out of suspension, thereby increasing particle residence times. The solid particles comprise combustible fuel particles, and non-combustible ash and contaminants. Control of the temperature of non-combustible particles and the wall surface prevents these non-combustible particles from adhering to, and building up on, the furnace wall. It is also advantageous to control the gas temperature leaving the furnace to minimize temperature-driven corrosion of downstream heat-exchange surfaces. Method and apparatuses are described to control the gas, non-combustible particle, and wall temperatures. The furnace can be integrated into a stand-alone boiler or as a combustor in which a portion of the pyrolysis gas from the combusting fuel is burned in a separate vessel.

摘要： The present invention is directed to additives for coal-fired furnaces, particularly furnaces using a layer of slag to capture coal particles for combustion. The additive(s) include iron, mineralizer(s), handling aid(s), flow aid(s), and/or abrasive material(s). The iron and mineralizers can lower the melting temperature of ash in low-iron, high alkali coals, leading to improved furnace performance.

摘要： A hybrid stepping motor has a connector housing formed integrally with an insulator having an upper insulator and a lower insulator. The hybrid stepping motor includes a stator core and output terminals concentrically disposed outside the stator core. A wiring pattern serving as the output terminals has connector pins and land portions disposed eccentrically with respect to one another. The land portions are formed on an outer edge side of the wiring pattern. A surface, which is an uppermost surface of the wiring pattern, is located below a lowermost surface, in which jumper wires and lead wires pass, of the lower insulator. The lead wires are pulled out from a lower side, and are pulled out to guiding grooves.

摘要： A combustion method and apparatus in which combustible matter, e.g., waste matter, coal, etc., is gasified to produce a combustible gas containing a sufficiently large amount of combustible component to melt the ash by its own heat. A fluidized-bed furnace (2) has an approximately circular horizontal cross-sectional configuration. A moving bed (9), in which a fluidized medium settles and diffuses, is formed in the central portion of the furnace, and a fluidized bed (10), in which the fluidized medium is actively fluidized, is formed in the peripheral portion in the furnace. The fluidized medium is turned over to the upper part of the moving bed (9) from the upper part of the fluidized bed (10), thus circulating through the two beds. Combustible matter (11) is cast into the upper part of the moving bed (9) and gasified to form a combustible gas while circulating, together with the fluidized medium. The amount of oxygen supplied to the fluidized-bed furnace (2) is set so as to be the same contained in an amount of air not higher than 30% of the theoretical amount of combustion air. The temperature of the fluidized bed (10) is maintained at 450° C. to 650° C. so that the combustible gas produced contains a large amount of combustible component. The combustible gas and fine particles produced in the fluidized-bed furnace (2) are supplied to a melt combustion furnace where they are burned at high temperature, and the resulting ash is melted.

摘要： A recovery boiler for combusting spent liquor from cellulose cooking while at the same time recovering chemicals. The recovery boiler is constructed for so-called "rotafire" combustion and the speed of rotation of the secondary air has been increased by a constriction of the boiler being arranged at the tertiary air level. The invention also includes a process for using the boiler which is based on certain ports through which the secondary air is blown in being provided with air which is at a higher pressure than that at the other ports on the same level, thereby achieving a higher inflow velocity than from the other ports.
