Travelling grate spreader stokers were not very popular in the Federal Republic of Germany, since for grate firings classified bituminous coals were in unlimited and inexpensive supply which could be burnt successfully on grates with hopper feeding. The steam generator outputs were varying between 1o and 28 kg/s (40 - 100 t/h). Due to the increased supply of unclassified bituminous coals with higher fine grain portions - mainly imported coals - on the market and required steam generator outputs greater than 28 kg/s the travelling grate firing with spreader stokers became attractive and necessary. As an example of the steam generator with 41.6 kg/s the plant set-up and operational experiences shall be described in the following. This plant has been constructed in a thermal power station in the South of Germany as an auxiliary steam generator for 740 MW unit fired with pulverized bituminous coal and for remote heating supply.
