摘要： A splitter divides a flow of low heating value biomass into a central stream and an annular stream. A stable flame may be achieved by combusting the central stream with oxygen. This avoids the use of costly fossil fuels or biomass (that have higher heating values than the biomass fuel) as an auxiliary fuel for achieving a stable flame.

摘要： A burner for introducing solid particulate fuel to a burning zone of a kiln such as a rotary kiln for manufacturing cement clinker or similar material includes a centrally located duct for conducting solid fuel to an inlet opening and at least one duct for conducting primary air to one or more annular nozzles surrounding the inlet opening of the centrally located duct. The centrally located duct for conducting solid fuel is arranged so that the direction of introduction of the fuel relative to the longitudinal axis of the burner and consequently the direction of introduction of the primary air may be adjusted continuously during operation of the burner.

摘要： In this combustion burner and boiler, interference of ignition in a flame stabilizer is suppressed and flame stabilizing performance is improved by providing: a fuel nozzle which ejects a fuel gas that is a mixture of pulverized coal and air; a combustion air nozzle which ejects a fuel gas combustion air from outside of the fuel nozzle; a secondary air nozzle which ejects secondary air from the outside of the combustion air nozzle; and a flame stabilizer which comprises a first flame stabilizer main body which is arranged at the leading end of the fuel nozzle and separated by a prescribed space from the inner wall surface of the fuel nozzle and which forms a ring shape having as the center an axial line along the ejection direction of the fuel gas.

摘要： The invention relates to a solid fired hot gas generator which comprises a plurality of solid burners for extending the regulating range, which form a multiple solid burner with an enlarged regulating range. A solid feed and a combustion air feed are assigned to each solid burner and with the aid of a dosing means a separate, dosed solid feed to each solid burner is guaranteed. The firing power of the multiple solid burner which is in particular a multiple impulse burner extends from the minimum power of one of the solid burners to the maximum power of all solid burners so that a regulation of all necessary load regions of a plant unit to be supplied is covered.
