摘要： The present invention describes a method and an arrangement for purifying the intake air of a gas turbine of solid particles and liquid droplets. According to the invention air is taken into the system of intake air passages (1, 2, 4) of the gas turbine and the particles contained in the intake air are collected by means of at least one plate filter (3) to which a collection voltage has been connected. In order to enable and enhance collection, the air is taken into at least one charging chamber (2) arranged at a distance prior to the plate filters (3) in the flow direction of the air, where an electric field is formed between at least two electrodes (5, 7) by connecting a voltage between the electrodes which exceeds the collection voltage, whereby powerful charging of the particles and at least partial removal of the water contained in the air are effected.

摘要： The invention is related to a method and apparatus for modifying the irradiation distribution of a radiation source. In accordance with the method the radiation source (1) is used to direct radiation to an essentially planar target surface (6). In accordance with the invention between the radiation source (1) and the target surface (6), several plates (4), which are essentially transparent to the radiation and have spaces between them, are placed close to the radiation source (1), in order to use the reflection and absorption of the transparent plates (4) to attenuate the radiation to desired areas.

摘要： To reduce nitrogen oxide emissions and corrosion in a bubbling fluidized bed boiler that burns biofuel or waste, air is supplied into the boiler furnace (1) in stages so that two sub-stoichiometric combustion zones (I), (II) and a superstoichiometric zone (III) are brought about. The first combustion zone (I) begins from the height level of primary air supply nozzles (3) and it extends above the fluidized bed (2), ending under the height level (hS) of secondary air nozzles (6). The second combustion zone (II) begins from the height level (hS) of the secondary air nozzles (6) and ends under the height level (hT) of tertiary air nozzles (7). The third combustion zone (III) begins from the height level (hT) of the tertiary air nozzles. The length of the first combustion zone (I) is optimized by placing the secondary air nozzles (6) at a height (hS) from the top surface of the fluidized bed (2), which height (hS) is chosen according to a given calculation formula and calculated according to furnace-specific variables, reference values and design point-specific variables. The design point-specific variables are different in a boiler with a high furnace load and in a boiler with a low furnace load.

摘要： To burn lean fuel gas in a furnace of a power plant boiler, a fuel gas flow is fed into the furnace via a fuel pipe (1), a primary air flow is fed centrally into the fuel gas flow discharging from an outlet (14) of the fuel pipe (1), and a secondary air flow is fed peripherally into the fuel gas flow discharging from the outlet (14) of the fuel pipe (1). The outlet (14) is provided with an inner stabilizing ring (4) and an outer stabilizing ring (8), both boosting flame ignition. The primary air channel (2) is provided with a first swirler (3) and the secondary air channel (6) is provided with a second swirler (7) to set the respective air flows into a rotation.

摘要： The invention relates to a method for feeding sludge containing organic material to, for example, a pressurized steam dryer: The wet sludge is fed to the dryer (7) by extruding it through at least one nozzle (3), the opening of which is arranged at a distance from the side (13) of the dryer (7) while a velocity at least sufficient to transport the sludge pneumatically in the dryer is set as the flow velocity of the gas being fed into the dryer (7). The sludge is fed by an eccentric screw pump (7), which can pressurize the sludge to the pressure in the dryer.
