摘要： Firing equipment that can be operated under turbocharge, especially fluidized bed firing equipment for a steam generator. At least two successively arranged air compressors are provided, including a first compressor that is driven by a first turbine, which is disposed on a common shaft with the first compressor, and forms together with the latter a turbocharger, with the energy needed for driving the first compressor being extracted from the flue gas of the turbocharged firing equipment. An air preheater is disposed between the second compressor and the firing equipment, with flue gas being supplied thereto. A second turbine drives the second compressor. At least during turbocharged operation of the firing equipment, the flue gas is conveyed at high temperature first to the second turbine then to the air preheater. An electrical apparatus that is operable at least as a generator is operatively associated with the second compressor and the second turbine.

摘要： In a method for operating a combination of a gas turbine process and a steam turbine process, in which the superimposed boosted gas turbine process is operated with compressed air and a combustible fluid, and the steam turbine process is operated via a fluidized bed furnace with a carbonaceous solid fuel, whereby the combustion in the fluidized bed furnace is performed with the oxygen-containing exhaust gases of the superimposed gas turbine process and electrical energy is generated with both processes, the efficiency is increased by expanding the exhaust gases of the superimposed gas turbine process only to an extent to which the fluidized bed furnace is operable as a pressurized fluidized bed and subjecting the exhaust gases of the pressurized fluidized bed furnace, after removing solid particles, to a second gas turbine process for further expansion and then to a heat exchange with the compressed air of the superimposed gas turbine process; the air for the superimposed gas turbine process is subjected to a two-stage compression with recooling, whereby the compressing energy for the first stage is derived from the second gas turbine process and the compressing energy for the second stage is derived from the superimposed gas turbine process.

摘要： A method of removing dust from a dust-laden gas using gas-permeable filter elements that are disposed in tanks, with the gas flowing through the filter elements from the outside to the inside thereof and depositing dust on the outer surfaces thereof. Deposited dust is removed from the filter elements by pressurized gas cleaning pulses applied to the interior of the filter elements. A plurality of tanks are supplied in parallel with partial streams of the dust-laden gas. The ratios of the pressure differentials that occur across the filter elements to the flow rates of the individual partial streams, which ratios increase with time during the formation of a dust layer, are determined. When the ratio of one of the tanks reaches an experimentally determined limiting value, this tank and all of the other tanks are simultaneously cleaned.
