Abstract:
A method and a device for monitoring the combustion of fuel in a power station are provided. An actual concentration distribution of a material in a combustion chamber is measured, the actual concentration distribution is evaluated, taking into consideration a combustion stochiometry, and conclusions are drawn regarding a composition of the fuel on the basis of the evaluation that has been carried out.

Abstract:
A burner assembly combines oxygen and fuel to produce a flame. The burner assembly includes an oxygen supply tube adapted to receive a stream of oxygen and a solid fuel conduit arranged to extend through the oxygen tube to convey a stream of fluidized, pulverized, solid fuel into a flame chamber. Oxygen flowing through the oxygen supply tube passes generally tangentially through a first set of oxygen-injection holes formed in the solid fuel conduit and off-tangentially from a second set of oxygen-injection holes formed in the solid fuel conduit and then mixes with fluidized, pulverized, solid fuel passing through the solid fuel conduit to create an oxygen-fuel mixture in a downstream portion of the solid fuel conduit. This mixture is discharged into a flame chamber and ignited in the flame chamber to produce a flame.

Abstract:
A control system for a power plant having a mill for pulverizing material for input into a combustion system of the power plant includes first and second sensors for recording first and second parameter of first and second outputs from the combustion system, respectively, an adjuster system for adjusting and recording at least one variable parameter of the combustion system, and a state estimator component configured to receive a first signal relating to the first parameter, a second signal relating to the second parameter and a third signal relating to the at least one variable system parameter. The state estimator component uses the first to third signals to produce a material parameter indicator signal and a system state indicator signal. The control system includes an output component configured to receive the material parameter indicator system state indicator signals and to combine these signals to produce an output control signal.
Abstract:
The invention relates to a method and a device for monitoring the combustion process in a power station, according to which the actual concentration distribution of a material and/or the actual temperature distribution are measured in the combustion chamber and conclusions are drawn regarding the type of combustion material on the basis of the measured actual concentration distribution or temperature distribution. A concentration distribution or temperature distribution of a material that has been determined using a sample fuel is compared with the measured actual concentration distribution or temperature distribution.

Abstract:
The purpose of the present invention is to provide new renewable energy by utilizing aluminum, which is easy to store and is stably suppliable, as a fuel without harming the environment or the human body. An aluminum powder and oxygen are introduced into a combustion chamber and subjected to stationary combustion, and the generated energy is taken out and utilized. The stationary combustion of aluminum is conducted by controlling either or both of the amounts of the aluminum powder and oxygen which are to be introduced into the combustion chamber. The control of the amount of the aluminum powder is accomplished by controlling the amount of the aluminum powder to be sucked into a jet stream of a carrier gas for introducing the powder into the combustion chamber or by controlling the amount of an impurity to be mixed with the aluminum powder. The control of the amount of the oxygen is accomplished by controlling the mixing ratio of the amount thereof to the amount of a diluent gas to be introduced simultaneously. The alumina resulting from the combustion is recovered, and aluminum obtained by reducing the alumina can be recycled as a fuel.
