Description

Die Erfindung betrifft einen Holztrockner für unmittelbare Feuerung mit geschweißter Doppelwandkammer, deren Innenmantel die Trockenkammer und das Heizaggregat mit seinem Wärmeaus.tauscherteil gasdicht umschließt. Es gibt seither Holztrockenanlagen für direkte Feuerung und in den letzten Jahren Holztrockemnaschinen für Speisung mit Dampf oder elektrischem Strom. In den ersteren, wird mit Temperaturen von Etwa 65° C getrocknet, in den letzteren mit Temperaturen über 10o° C. Es wurden auch Hochtemperaturtrockner beschrieben., bei welchen- eine direkte Feuerung mit dem Holztrockner verbunden ist. Diesen Trocknern haftete jedoch der Mangel an, daß die Temperatur nicht genau geregelt werden konnte. Bei der Trocknung mit Temperaturen über 10o° C ist dies jedoch eine unbedingt zu erfüllende Forderung.The invention relates to a wood dryer for immediate firing with welded double-walled chamber, the inner jacket of which is the drying chamber and the heating unit encloses gas-tight with its heat exchanger part. There have been wood drying systems since then for direct firing and, in recent years, wood drying machines for feeding with steam or electricity. In the former, with temperatures of about 65 ° C, in the latter with temperatures above 10o ° C. There were also High-temperature dryer described., In which a direct firing with the Wood dryer is connected. These dryers, however, had the disadvantage that the Temperature could not be precisely controlled. When drying with temperatures However, above 10o ° C this is a requirement that must be met.

Es ist ein oben beschriebener Trockner i für direkte Feuerung mit gasdicht geschweißter Doppelwandkammer z, deren Innenmantel 3 die Trockenkammer und das Heizaggregat mit seinem Wärmeaustauscherteil5 gasdicht umschließt, erfindungsgemäß in der Art ausgebildet, daß ^ zur Verwertung von Holzabfällen - Holzgas in einem besonderen Kessel 6 erzeugt wird, dessen Strömung durch eine von einem Trockenraum befindlichen Thermostat 7 gesteuerte Absperreinrichtung 8 in der Verbindungsleitung 9 'vom Holzgaserzeuger 6 zu dem unterhalb des Wärmeaustauschers 5 angeordneten Heizaggregat geregelt wird.It is a dryer as described above for direct firing with gas-tight welded double-walled chamber z, the inner jacket 3 of which is the drying chamber and encloses the heating unit with its heat exchanger part 5 in a gas-tight manner, according to the invention trained in such a way that ^ for the recovery of wood waste - wood gas in one special boiler 6 is generated, the flow of which through one of a drying room located thermostat 7 controlled shut-off device 8 in the connecting line 9 'from the wood gas generator 6 to the heating unit arranged below the heat exchanger 5 is regulated.

PATENTANSPRÜCHE: i. Holztrockner für unmittelbare Feuerung mit geschweißter Doppelwandkammer, deren, Innenmantel die Trockenkammer und das Heizaggregat mit seinem Wärmeaustauscherteil gasdicht umschließt, dadurch gekennzeichnet, daß Holzgas, in einem besonderen Kessel (6) erzeugt wird, dessen Strömung zum Heizaggregat durch eine von. einem im Trockenraum befindlichen Thermostat gesteuerte Absperreinrichtung (8) in der Verbindungsleitung vom Halzgaserzeuger zu dem unterhalb des Wärmeaustauschers (5) angeordneten Heizaggregat geregelt wird. PATENT CLAIMS: i. Wood dryer for direct firing with welded double-walled chamber, the inner jacket of which encloses the drying chamber and the heating unit with its heat exchanger part gas-tight, characterized in that wood gas is generated in a special boiler (6), the flow of which to the heating unit is through one of. a thermostat-controlled shut-off device (8) located in the drying room in the connecting line from the pulp gas generator to the heating unit arranged below the heat exchanger (5). 2. Trockner nach Anspruch i, dadurch gekennzeichnet, daß die Verbindung zwischen dem Halzgaserzeuger (6) und dem Heizaggregat durch zwei Leitungen (9) und (io) hergestellt wird, so daß die Heizleistung durch ein größeres und ein kleineres Heizaggregat geliefert wird, wobei die von dem im Trockenraum befindlichen Thermostat gesteuerte Absperreinrichtung in der einen und/oder der anderen Leitung angeordnet ist. 2. Dryer according to claim i, characterized characterized in that the connection between the Halz gas generator (6) and the heating unit is made by two lines (9) and (io), so that the heating power through a larger and a smaller heating unit is supplied, whereby the one from the im Thermostat-controlled shut-off device located in the drying room in the one and / or the other line is arranged. 3. Holztrockner nach Anspruch i oder 2, dadurch gekennzeichnet, daß zwischen dem Holzgaserzeuger und dem Heizaggregat eine weitere Leitung (i i) mit sehr kleinem Querschnitt verlegt wird, deren Flamme im -Verbrennungsraum als Zündflamme während des ganzen Trockenprozesses brennend bleibt, auch'wenn Grundlast und Spitzenlast durch den Thermostat abgeschaltet sind. .3. Wood dryer according to claim i or 2, characterized characterized in that between the wood gas generator and the heating unit another Line (i i) is laid with a very small cross-section, its flame in the combustion chamber remains burning as a pilot flame during the entire drying process, even if the base load and peak load are switched off by the thermostat. .
