Operating method for a solid fuel burner

Operating method for a solid fuel burner,

• characterized in that
• the start of the burner is performed with a starting combustion material—combustion material group 1—which does not form aggressive substances such as acids at a temperature below the burner operating temperature applicable to the burner, that, to this end, the combustion material is supplied from a first combustion material entry (7a) predetermined for this purpose, wherein the second combustion material entry (7b) for the main combustion material—combustion material group 2—is initially not yet active, that upon reaching the operating temperature of the burner the combustion material supply at said first combustion material entry (7a) is deactivated and, instead, the combustion material supply at the second combustion material entry (7b) for the main combustion material is activated,
• that the continuous operation of the burner is continued—provided that its temperature is not below its operating temperature—wherein, if the second combustion material entry (7b) is configured as a multiway entry, it can be supplied with alternative combustion materials in combustion material group 2 clocked with respect to time or in dependence on other conditions and can be performed clocked with respect to its operation,
• that the termination of the combustion process, when the burner is currently in the state of combusting combustion material of combustion material group 2, is performed in dependence on the current combustion conditions either in such a way that initially the combustion material supply of combustion material group 2 is deactivated and the combustion material supply of combustion material group 1 is activated, and that the combustion is then stopped out of this combustion material group, or that the combustion is stopped in the state of combusting combustion material of combustion material group 2.
