    摘要： Disclosed is a method for setting parameters of a load feedforward controller for superheated steam temperature control, which belongs to the technical field of thermal automatic control. This method adds a load feedforward controller to the conventional boiler superheated steam temperature spray desuperheating cascade control system. The application provides a structure of the load feedforward controller, and a method for designing the parameters of the load feedforward controller according to the dynamic characteristics of the superheated steam temperature related to feed coal flow disturbance, feedwater flow disturbance and desuperheating water spray disturbance. The method of the application could effectively reduce the superheated steam temperature deviation in the process of unit load rise or drop, and the design method is simple, effective and easy to realize in engineering.

    摘要： A wall-fired burner includes a fuel tip defining a fuel direction axis and a fuel tip pivot axis perpendicular thereto. A first air tip is adjacent to the fuel tip. The first air tip defines a first air direction axis and a first air tip pivot axis perpendicular thereto. A second air tip is adjacent to the fuel tip, opposite from the first air tip across the fuel tip. The second air tip defines a second air direction axis and a second air tip pivot axis perpendicular thereto. A mechanism operatively connects the fuel tip, the first air tip and the second air tip for at least one of independent and/or joint movement of the fuel tip, the first air tip and the second air tip.
