摘要
In a method for operating and controlling a coal-fired steam boiler power plant whose steam boiler is designed for combustion-air-based coal combustion in the steam boiler by the heat transfer to the steam mass flow achievable steam parameters, a solution is to be created, which allows a coal power plant to design a method of operating a coal-fired power plant for oxy-fuel operation. This is achieved in that in the boiler combustion of the carbonaceous fuel after the oxyfuel process with approximately pure, more than 95 vol .-% O2 containing oxygen and recirculated, high CO2-containing flue gas is carried out such that the mass flows of all the In their respective composition ratio of oxygen and / or flue gas in their respective composition ratio of oxygen and / or flue gas formed and matched to each other, that taking place in the boiler by flame radiation, gas radiation and convection Heat transfer to the steam mass flow in the steam / water cycle compared to the air combustion is kept the same overall, in particular the same steam parameters are obtained.
