Load-dependent operated apparatus for the combustion of solid biogenic fuels and methods for their operating

摘要

The device (1) has a feed device (4) for feeding fuel into a combustible material bed (7) in a combustion stage (2) i.e. basic heat load compensating firing stage. An ignition unit ignites the fuel in the bed. A combustion chamber (11) is provided above the bed. A heat exchanger (13) is provided with a downstream heat accumulator. The combustion chamber and the heat exchanger are arranged in a heat flow of burnt combustible material. A self-igniting fuel feeding device (10) is provided in the combustion chamber in a heat demand peaks covering firing stage (3). The fuel of the heat demand peaks covering firing stage is a liquid or gaseous fuel or crushed solid biogenic fuel. The ignition unit is designed as an electrical ignition coil. An independent claim is also included for a method for operating a load-dependently operated device.
