METHOD FOR CONTROLLING A COMBUSTION DEVICE

The invention relates to a method for controlling a combustion process of a gas turbine. A combustion chamber, a control device in which a calculation model of a combustion process is stored, and an exhaust gas measurement device are required. First, permissible limit values for nitrogen oxides and carbon monoxide as hazardous substances are determined. The actual value of at least one of the two hazardous substances is continuously measured in the exhaust gas. If a signal for reducing the power of the gas turbine to the lowest possible value is given, a minimum fuel delivery is calculated, in which the limit value is followed. The fuel delivery is then reduced until either the calculated minimum fuel delivery is reached or until the continuously measured fraction of the hazardous substance reaches the permissible limit value. 本发明涉及一种用于控制燃气轮机的燃烧过程的方法。需要燃烧室、保存有燃烧过程的计算模型的控制装置以及废气测量装置。首先确定作为有害物质的氮氧化物和一氧化碳的允许的极限值。在废气中持续地测量两种有害物质中的至少一种有害物质的实际值。如果给定用于将燃气轮机的功率减小到最低可能的值的信号，则计算最小燃料输送，在最小燃料输送的情况下遵守极限值。然后减少燃料输送，直至要么达到所计
