Abstract: A method and configuration suited to feeding a water-containing fuel such as peat or brown coal into a pressurized space such as a pressurized dryer or a high-pressure gasifier. A fuel with a high moisture content requires drying in a dryer prior to gasification or combustion. In the dryer, the fuel is dewatered, whereby the separated water is discharged as steam from the dryer. The generated steam is separated from the fuel flow exiting the dryer and it can be routed as injection steam to a gas turbine. When a portion of the steam extracted from the fuel flow exiting the dryer is fed into the fuel entering the dryer or to a heat exchanger, which is employed for heating the fuel flow, a fuel of higher moisture content can be fed into the dryer, or alternatively, the moisture content of the fuel can be increased to improve the feed of the fuel. The method imparts no reduction of the economy of the energy generation process.

Abstract: A solid fuel boiler with one or more fuel chutes configured to pre-dry wet solid fuel prior to loading into a combustion chamber of the boiler, enabling higher thermal efficiencies and burning less fuel to produce the same steam quantity. The pre-drying fuel chutes pass through the boiler where hot combustion gases radiantly and convectively—heat the chute walls to dry the wet solid fuel by radiant, convective, and/or conductive heating. Agitator mechanisms or structures within the chute mix the fuel for uniform heating, break up clumps of wet fuel, regulate the speed of falling fuel, prevent sticking, dry the fuel by means of steam and/or hot air, transport and deliver a cooling medium while a chute is offline in an operating boiler, and suppress fire using steam injection. Fuel from the chute can flow into a fuel storage bin or directly into the combustion zone of the furnace.

Abstract: The invention relates to a lignite fired steam power plant comprising a water/steam power cycle, a dryer system for drying lignite coal and a heat recovery system for recovering thermal energy from the dryer system. The heat recovery system vaporises condensate against a vapour line of the dryer steam and then compresses the vaporised condensate for use to preheat either or both combustion air or condensate of the water/steam power cycle.

Abstract: The invention relates to a nozzle bottom device and to a method for operating the latter. The nozzle bottom arrangement has a nozzle group with first nozzles and a further nozzle group with second nozzles. The two nozzle groups can be supplied independently of each other with a fluidizing medium. The respective volumetric flow can be switched on and off or can be adjusted variably. The first nozzles and the second nozzles are uniformly distributed over the entire surface of the nozzle bottom arrangement. As a result, a homogeneous fluidized bed is produced in the fluidized bed dryer irrespective of whether only one of the nozzle groups or all of the nozzles is or are operated.

Abstract: A pelletizing process and pelletized product is provided using non-food or limited-feed agricultural residue, such as corn stover and soybean stubble, and for various uses, including energy production, such as ethanol or electricity generation, fuel and feed. The agricultural plant material is harvested and baled. The bales are transported to the processing site for storage or immediate processing. The bale strings are first removed, and then the broken bales are shredded. The shredded plant material is then ground to a small size. The ground material is then pelletized without the use of binding additives, to produce densified pellets of the agricultural plant material. The pellets are cooled and then stored or transported to an end user. Chemical agents may be added to depolymerize lignin in the residue material. Nutritional supplements may be added to the material before pelletizing.
