Abstract

Described and illustrated is a washer (2) for cleaning, in particular for desulfurizing, gases (4), preferably flue gases, on a watercraft, in particular a ship (1), or an offshore structure, comprising a gas supply line (9), a gas discharge line (12), a wash liquid supply line (17), a wash section (10) for washing the gas (4) with the wash liquid (11) supplied via the wash liquid supply line (17), a collecting section (13, 27) for collecting wash liquid (11) after the gas (4) has been washed in the wash section (10), and a wash liquid discharge line (14) for discharging the wash liquid (11) from the collecting section (13, 27). To be able to ensure a reliable discharge of the wash liquid from the collecting section, provision is made that the wash liquid discharge line (14) at least partially accommodates an immersion line (21, 31) which protrudes upwards from an open end (22) of the wash liquid discharge line (14) for allowing the wash liquid (11) to flow out of the collecting section (13, 27) into the wash liquid discharge line (14), and that a gap (S) is provided at least in part between the immersion line (21, 31) and the wash liquid discharge line (14).

Abstract

The invention relates to a method for using a fuel, preferably fossil fuel, in particular lignite, to generate electricity. In order that the generation of electricity by means of fuels, such as fossil fuels, for example in the form of bituminous coal or lignite, or in the form of biomass, can be made more economical and environmentally friendlier, according to the invention, solar radiation (4) is concentrated by means of at least one mirror (3), the thermal energy of the concentrated solar radiation (4) is used to produce and/or superheat steam and/or to heat air, and the steam produced and/or superheated by means of the concentrated solar radiation (4) and/or the heated air is coupled in-line as a thermal heat source into a power plant process operated with a fuel.

Abstract

The invention relates to a receiver (5) for a solar tower power plant (1, 30), having at least one receiver module (13) for the absorption of solar energy from solar radiation concentrated onto the receiver module (13) by mirrors (2), having a supply line (7) for supplying water (6) to be evaporated in the receiver module (13) and having a steam line (9) for discharging water (6) evaporated in the receiver module (13), wherein the receiver module (13) has a modular distributor (14) connected to the feed line (7). In order to devise a receiver which is more economical and nevertheless simple and reliable to operate, provision is made for the receiver module (13) to comprise a modular collector (16) connected to the steam line (9) and arranged above the modular distributor (14), and a multiplicity of modular pipes (15) connecting the modular distributor (14) and the modular collector (16) to one another, and for the receiver module (5) to be formed as a forced flow steam generator.

Abstract

The invention relates to a flue gas device (2) for cleaning flue gases (4) on ships (1), comprising at least one flue gas scrubber (10) and at least one washing water purifier (17), wherein at least one flue gas line (9), at least one washing water line (15) and at least one washing water outlet (14) are associated with the flue gas scrubber (10) and the washing water outlet (14) is connected to the washing water cleaning device (17). The aim of the invention is treat the contaminated water on board as simply as possible and using as little space as possible. According to the invention, the washing water purifier (17) comprises at least one filter material (32) for separating particles from the washing water (11), a purification device (43) for removing the particles sticking to the filter material (32) is associated with the filter material (32), and the washing water purifier (17) comprises a purification line (19) for evacuating particles.

Abstract

The invention relates to a burner, particularly a jet burner, for burning pulverised fuel, particularly brown coal, comprising at least one fuel channel (3) with an opening oriented in the direction of a combustion chamber, and at least one air nozzle (1, 5, 6) oriented in the direction of the combustion chamber, the fuel being blown through the fuel channel (3) into the combustion chamber, and the fuel channel having a rectangular cross-section. Torque is applied in order to partially break up the strands of pulverised coal created during operation, thereby bringing forward the ignition and improving the burn-out of the coal, as well as obtaining low emission values. Construction costs are also significantly reduced compared to the costs of constructing a completely new burner. This is achieved by arranging a plurality of guiding elements (10, 11, 12, 14) in the at least one fuel channel (3) in order to apply an at least partially rotating or whirling flow, the guiding elements (10, 11, 12, 14) being arranged only in the region of the walls of the fuel channel (3) such that the inner region (3') remains free of built-in elements.
