Abstract

Stove ( 1 ), characterized in that the pulling system consists of two lateral fall trains (2) and two lateral ascending trains (3) in the region of the heat exchanger surfaces. The trains are arranged symmetrically and lined with vermiculite or fireclay plates in the area of the fall train.

Description

State of the art:

at usual Stoves is often the problem that the cladding of the stove remains cool and therefore not to Space heating can contribute. For some devices, only the top part becomes the outer shell is heated, in the The lower part of the stove remains cold even after a long period of operation. The predominant generation of convection heat leads to repeated swirling Of fine dust and pathogens, there is also the risk of thermal Degradation of dust to particularly harmful reaction products.

The Air temperature must be in convection models because of the low IR Radiation component are chosen to be particularly high physiological to allow a pleasant stay in the heated room. The high air temperature leads however to a decrease of the humidity, thus to one for skin and Respiratory organs unpleasant condition.

The Flue gas emissions of stoves are critical as they affect regional air quality can. Many small fireplaces burden with high pollutant emissions the environment too, losing the controlled emission limits for larger equipment in this way their meaning.

Especially the released fine dusts are so far more likely to have a negative impact on health underrated Service. In normal stoves will not be special measures met in order to meet this problem in a special way.

solution of the problem:

The invention relates to a wood-burning stove ( 1 ), which avoids the disadvantages described by design features.

The Exhaust gas line in a stove essentially determines the characteristics of the heat emission. To the heat release especially in the lower part of the device the flue gases are deflected downwards on exit from the combustion chamber, then after 180 ° deflection after along the top of the heat exchanger surfaces to stream.

Thereby will be a rapid and strong warming the outer skin achieves the storage capacity of the cladding panels well is being used,

To The first deflection of the flue gases flow in one with insulating refractory material lined channel down, thereby can a clean burnout of the flue gases can be achieved.

at the subsequent 180 ° deflection after above, dust particles are separated by centrifugal force and over Sheet fed to the ashtray.

Around to allow heating and refueling at low smoke reduction a bypass flap is provided in the ceiling of the firebox, which a direct way to the exhaust nozzle releases.

The Rust in the bottom of the firebox is closed at operation by one faulty flow in the train system and to keep the ember bed longer.

The secondary air we preheated and extensively finely dosed added to a good mixture with the Feuerungsgasen to achieve and thus achieve an effective secondary combustion. The purge air for the windscreen is forwarded above the combustion chamber in channels forward There as an air curtain in front of the disc exit.

The heat-emitting outer shell, consisting of tiles or plates, is in direct contact or with a small gap with the basic structure ( 3 ) of the furnace, so that no convection between plates and basic structure can arise. This gives us a greater share of the heat generated than radiant heat. As a material for the plates in question: ceramic, steel, clay, concrete, natural stone.

The plates are fastened with clamps or rails ( 2 ) attached to the basic construction, in the remaining gap between the base construction and can be a heat-resistant, elastic material such as mineral or ceramic wool, or string made of ceramic or glass fibers to achieve a defined position of the cladding panels.
