Pressure-fired fluidised-bed boiler plant

摘要

The pressure-fired fluidised-bed boiler plant comprising a set of gas turbines driven by the flue gases, in its main air line (8) has a preheating burner (10) which heats the still cold fluidised-bed boiler (1) and part of the flue gas duct (12) to above the dew point. Air shunted off from the main air line (8) is heated in a heat exchanger (20) and is used for heating the turbine (5) driven by the motor (6) and the remaining parts of the installation which have flue gas flowing through them. <IMAGE>
