Abstract: The subject of the invention is a method as well as an apparatus for suppressing flow vortices within a turbo power machine with a premix burner, into which fuel and air are introduced for mixing, which then leave the burner downstream along its burner axis in the form of a fuel/air mixture through a burner outlet and flow into a combustor located downstream from the burner in the flow direction of the fuel/air mixture. The invention is based on the basic idea of—for the fluid-mechanical stabilization of a premix burner, into which at least one combustion air stream (5) is fed tangentially into a burner chamber (6) and is mixed with an injected gaseous and/or liquid fuel (7;8) while forming a swirl flow (9) oriented coaxially to the burner axis and induces a reverse flow zone (15) at a change in the cross-section on a burner mouth (14), that is used during the operation of the burner to stabilize the flame—increasingly, radially deforming the swirl flow (9) within the burner chamber (6) in the direction of the burner mouth (14) and let it enter the combustor (12) in a non-rotation-symmetrical flow cross-section, whereby this deformation is created by reducing the free flow cross-section (18) of the burner chamber (6). The fuel/air mixture flows into the combustor with a non-rotation-symmetrical flow cross-section.

Abstract: An automated, real-time control of a waste incineration plant is disclosed for treating waste of variable moisture content. In an exemplary method of and a system for controlling a waste combustion process, time varying process parameters of the waste combustion process, such as a water content of the incoming waste, are estimated via a parameter estimation algorithm for time varying parameters based on Kalman Filters. The estimated process parameters can then used to determine, in a controller for real-time control of the waste incineration plant, control parameters, such as a waste feed rate, corresponding to input variables of a model of the waste combustion process.

Abstract: An on-line degradation monitoring is disclosed for boiler tubes in large combustion facilities, in particular waste incineration plants. The degradation of the tubes, for example corrosion or caking, is determined in a more or less continuous manner while the combustion facility is operating, and thus not restricted to optical inspection during downtimes. A rate or accumulated degradation can be related to an operation mode of the facility. Appropriate degradation sensors are arranged outside of a the flue gas tract where the boiler tubes are exposed to noxious flue gases from the combustion process, and receive ultrasonic signals from a space or volume within the flue gas tract. A test tube is provided exclusively for the monitoring of the degradation progress and introduced into the flue gas tract at a particularly corrosion-exposed location.
