Due to the design of the combustion chamber according to the invention, it is also possible to fire logs with a length of approximately 1/3 meter at a stove depth that is adapted to the current fitted kitchen furniture. This is the length that is currently the most common in the trade.

  • the flue gases now pass through the flap opening to the exhaust pipe.
  • the intermediate plate turns the upper part of the cooker into a baking, roasting and grill room.
  • An embodiment of the invention provides that the combustion chamber is delimited at the bottom by a flap located behind the furnace door and pivotable about a horizontal axis, and that the upper edge of the flap ends with the intermediate plate.

  • the stove can be used to burn wood as well as coal.
  • a shelf with a grate is used and this grate is open, coal can be burned in the stove. If a closed support is used at the bottom or the grate is closed, the stove can be fired with wood. A removable insert with a closed support is only used to remove fired goods.

  • Bascules are opened unintentionally, which would cause the door to fall out of its holder.
  • This overloading of the fireplace also means that the safety temperatures in the area of the fireplace, which are measured in the test area in accordance with individual fireplace standards, can rise considerably for a short time.
  • Another phenomenon that occurs in solid fuel fireplaces is that due to the desired controllability of the fireplaces and the large control ratio in the minimum load range, the exhaust gas mass flow is so low that it is present in the subsequent exhaust gas line (connecting piece, chimney) cools down, so that at low exhaust gas temperatures it is possible that the dew point in the exhaust line is not reached. This process occurs, for example, when lignite briquettes are fired and wood is not deposited and is not perfectly dry.

This additional amount of air lowers the exhaust gas temperature and the combustion of CO gases.
  • there is a reduction in the performance of the fireplace because due to the lower resistance to the ember bed, the amount of exhaust gas conveyed by the chimney is filled up by the false air.
  • the switching of the flap and the regulation of the supply of secondary air in the low or minimum load range can be controlled to the contrary, so that even a small amount of air is supplied to the fireplace when the velocity of the exhaust gas mass flow falls below a lower value . This delays cooling of the exhaust gases in the connector and in the chimney.
