摘要: When a boiler plant (100), which is equipped with an air plenum (104), is in operation, during the startup phase the admission pressure in this air plenum (104) is lowered in terms of time and amount via a blowoff device (106) with respect to combustion air (7) and startup air (105) made available from this air plenum (104). The air coefficient to the burner is consequently reduced. This ensures that, by means of such a near-stoichiometric fuel/air mixture, favorable ignition conditions are provided in the burner and the pollutant emissions during the startup phase are greatly reduced.
