View into the combustion chamber of a biomass cogeneration plant ( grate furnace )

As combustion chamber , combustion chamber , or fuel (s) room (the latter particularly in Brennerfeuerungen ) is referred to in the Feuerungstechnik part of a furnace in which the combustion with an open flame occurs.

The purpose of the combustion chamber is to allow the fuel sufficient dwell time in the flame before the exhaust gas hits convection heating surfaces (heat exchanger pipes ). In this way, complete burnout is ensured and carbon monoxide formation is minimized.

Since there is usually a temperature of approx. 800 - 1300 ° C (depending on the fuel and type of furnace) with intense heat radiation in the furnace , it is necessary that the furnace walls are refractory and / or cooled with water. In the latter case, the heat energy is already transferred to the heat transfer medium in the furnace .

The steam boilers of steam power plants essentially consist of a burner chamber which is clad with the evaporator tubes .
