Description

Dampfkesselanlage mit einem oder mehreren drehbaren Luftvorwärmern. Bei Wasserrohrdampfkesseln ist es bereits bekannt, die Wärme der Abgase in einem oberhalb des Dampfkessels angeordnetenLuftvorwärmer auszunutzen. Derartige Dampfkesselanlagen nehmen jedoch einen großen Platz ein.Steam boiler system with one or more rotatable air preheaters. In water tube steam boilers, it is already known to heat the exhaust gases in one take advantage of the air preheater arranged above the steam boiler. Such steam boiler systems however, occupy a large space.

Den Gegenstand _der Erfindung bildet eine Dampfkesselanlagemit dem bekannten drehbaren Luftvorwärmer, der an einen sonst nicht ausgenutzten Raum verlegt ist, und zwar zwischen den Aschenraum und den unteren Teil des Schornsteines. Diese Anordnung bietet noch den Vorteil, daß die Kanäle für die Führung der Abgase zum Schornstein und für die Verbrennungsluft zur Feuerung kurz werden.The subject of the invention is a steam boiler system with the known rotatable air preheater, which relocated to an otherwise unused space between the ash chamber and the lower part of the chimney. These Arrangement still has the advantage that the channels for guiding the exhaust gases to The chimney and the combustion air for the combustion will be short.

In der Zeichnung ist ein Senkrechtschnitt durch eine Kesselanlage veranschaulicht, und . zwar bei einem Wasserrohrkessel mit Regenerativ-Luftvorwärmer.The drawing shows a vertical section through a boiler system illustrates, and. with a water tube boiler with a regenerative air preheater.

Die Feuerung ist mit Kettenrost 7 versehen, von welchem die Verbrennungsgase die Wasserrohre 6 in der Richtung des Pfeiles 8 bespülen. Bei den bisher bekannten Wasserrohrkesseln strömen die Abgase dann meistens durch den Kanal 9, der durch eine Drosselklappe i i abgesperrt werden kann, zum Schornstein io. - Gemäß der Erfindung werden die Abgase in der Richtung des Pfeiles 12 durch den Regenerativ-Luftvorwärmer 13 dem Schornstein io durch. den Kanal14 zugeführt, während die Verbrennungsluft zur Feuerung dem Raum 15 um den Regenerativ-Luftvorwärmer herum entnommen wird, durch welch letzteren die Luft in der Richtung des Pfeiles 16 zur Feuerung unterhalb des Kettenrostes 7 strömt. Auf dem Wege der Verbrennungsluft und der Abgase sind verschiedene Drosselklappen 17, 18, i9 vorgesehen, um die Gas- und Luftströme zu regeln. Diese Regelung kann auch in der Weise ausgeführt werden, daß der Dampfkessel ohne Verwendung des Regenerativ-Luftvorwärmers geheizt werden kann, wobei die Drosselklappen 17 und 18 geschlossen werden und der Schieber i r geöffnet wird, so daß die Abgase von den Wasserrohren unmittelbar zum Schornstein gelangen. Der Raum, in welchem der L uftvorwärmer angeordnet ist, also der Raum zwischen dem Schornstein io und dem Aschenraum 2o, ist in der Regel bei Dampfkesselanlagen vorhanden. Er liegt sehr nahe der Feuerung und gleichfalls nahe dem Kanal, durch welchen die Verbrennungsgase von den Wasserrohren zum Schornstein gelangen.The furnace is provided with a chain grate 7, from which the combustion gases flush the water pipes 6 in the direction of arrow 8. With the previously known Water tube boilers, the exhaust gases then mostly flow through the channel 9, which through a throttle valve i i can be shut off to the chimney io. - According to the invention the exhaust gases are in the direction of arrow 12 through the regenerative air preheater 13 through the chimney. the duct 14 is supplied while the combustion air is taken from room 15 around the regenerative air preheater for firing, by which the latter the air in the direction of arrow 16 to the furnace below of the chain grate 7 flows. Are on the way of the combustion air and the exhaust gases various throttle valves 17, 18, i9 are provided to control the gas and air flows rules. This control can also be carried out in such a way that the steam boiler can be heated without using the regenerative air preheater, with the throttle valves 17 and 18 are closed and the valve i r is opened, so that the exhaust gases get directly from the water pipes to the chimney. The room in which the air preheater is arranged, i.e. the space between the chimney and the ash room 2o, is usually available in steam boiler systems. He lies very much near the furnace and also near the channel through which the combustion gases get from the water pipes to the chimney.

Besteht die Dampfkesselanlage aus zwei oder mehreren Dampfkesseln, so wird der Luftvorwärmer ebenfalls in dem besagten Raun angeordnet, wobei er auch in zwei oder mehrere Teile aufgeteilt sein kann.If the steam boiler system consists of two or more steam boilers, so the air preheater is also placed in the said room, and he too can be divided into two or more parts.
