Abstract:
A thermodynamic system that produces mechanical, electrical power, and/or fluid streams for heating or cooling. The cycle contains a combustion system that produces an energetic fluid by combustion of a fuel with an oxidant. A thermal diluent may be used in the cycle to improve performance, including but not limited to power, efficiency, economics, emissions, dynamic and off-peak load performance, and/or turbine inlet temperature (TIT) regulation and cooling heated components. The cycle preferably includes a heat recovery system and a condenser or other means to recover and recycle heat and the thermal diluent from the energetic fluid to improve the cycle thermodynamic efficiency and reduce energy conversion costs. The cycle may also include controls for temperatures, pressures, and flow rates throughout the cycle, and controls power output, efficiency, and energetic fluid composition.
Abstract:
The invention relates to a method for operation of a burner (1), whereby a mixture used for burning is supplied to the burner (1) in a two-stage process. In a first step atomised water is mixed with combustion air (L) and said mixture is mixed with a fuel in a second step and then supplied to the burner. Said burner comprises means for carrying out the above method.
Abstract:
The invention relates to an operating method for a hybrid burner (20). The hybrid burner (20) has a premix burner (22) and a pilot burner (21). The premix burner (22) comprises a premix air supply duct (4) that leads into a premix fuel supply duct (8, 12, 16). The pilot burner (21) comprises an air supply duct (3) and a fuel supply duct (1, 2) for liquid and/or gaseous fuel. When the hybrid burner (20) is in operation, air is fed via the air supply duct (3) and the premix air supply duct (4), oil is fed via the fuel supply duct (1) and water is fed via the premix fuel supply duct (8, 12, 16).
Abstract:
Es wird von einem Verfahren zur Verbrennung von brennbarem Abfallstoff in einer Brennkammer ausgegangen, bei dem der Abfallstoff einer Brennerflamme zugeführt und darin mit Verbrennungsluft bei einer Temperatur im Bereich zwischen 1100°C und 1700°C verbrannt wird. Um hiervon ausgehend Verfahren zur Verfügung zu stellen, das eine Kapazitätserhöhung von Anlagen zur exothermen Verbrennung von Abfallstoffen erlaubt, wird erfindungsgemäß vorgeschlagen, dass mindestens ein Teil der Verbrennungsluft durch ein sauerstoffreiches Gas mit einem gegenüber Luft erhöhten Sauerstoffgehalt ersetzt wird, und dass das sauerstoffreiche Gas mit einem Kühlmedium vermischt wird.
Abstract:
A device for generating additional energy in a power plant having a combustor (1) with a bed (4), to which air and fuel are intended to be supplied for combustion of the fuel therein while forming hot flue gases over the bed, and a gas turbine driven by these flue gases for generating energy, comprises means (21) arranged to supply additional fuel in the path (22) of said flue gases between said bed and the gas turbine for utilising excess oxygen available in the flue gases for combustion of this fuel there and members (23) arranged to supply a cooling medium to the flue gases in connection with said supply of additional fuel to the flue gas path for regulating the temperature of the flue gases to a desired level.
Abstract:
An incinerator (3) is mounted on a vehicle (1) which is adapted to carry thereon medical refuse, and a main burner (7) in which oil or water is suitably injected is provided in a main furnace (4) of this incinerator. Medical refuse discarded from medical facilities and suspected to cause secondary infection or direct infection is collected and is then at once disposed in the incinerator so as to be burnt.
Abstract:
A burner apparatus for burning hydrocarbons comprises a body (16) defining a plurality of nozzle ports (48) therein, each port facing in a different direction, a discharge nozzle (56) disposed in each nozzle port, and optionally a water ring assembly (14) disposed around the body. Each nozzle is held in place by a retainer (64) such that a first gap (76) is defined therebetween, and a retainer nut (84) is attached to the body adjacent to the retainer such that a second gap (90) is defined between the retainer and the nut. This second gap acts as an air discharge orifice and is in communication with an air passage (94) defined in the body. The water ring assembly (14) comprises an outer ring (110) and an inner ring (112) which combine to define an annular water chamber (128) therebetween. The water chamber is in communication with a plurality of notches (136) in the outer ring which act as water discharge nozzles for directing a water stream toward the burning petroleum and air stream discharged from the apparatus. The notches are fully exposed when the water ring assembly is disassembled, thereby making cleaning of the notches a simple matter.
Abstract:
The oven described comprises a heat exchanger (A) for heating a flow medium, in particular water, and two heat exchangers (B, C) for pre-heating the combustion air. The exchanger (A) is designed as an oven jacket (1) with a twin-wall, from which are extracted, in a metered manner, the combustion fumes by means of two channels (G, H) and into which is introduced, in a metered manner, the combustion air by means of four horizontal tubes (20, 21) provided with lateral outlet air passages (22). The heat exchangers (B, C) consist of sections (G', H') of the channels (G, H) and of two air guide tubes (30, 31), which communicate on the one hand with the outside atmosphere and are connected, on the other hand, with the tubes (20, 21) projecting into the oven jacket (1).
