Description

Speisewasserverdampferanlage Bei Abhitzeanlagen, bei welchen mit Hilfe eines Wasserumlaufes zwischen einem Rauchgasvorwärmer und einem Entspannungsgefäß Dampf erzeugt wird, läßt sich das Umwälzwasser des Rauchgasvorwärmers in wirtschaftlicher Weise zur Destillation des Zusatzwassers ohne besondere Brennstoffaufwendung benutzen. Die Erfindung betrifft eine derartige Speisewasserverdampferanlage mit Beheizung des zur I Krafterzeugung dienenden Dampfentwickers durch Umwälzen von durch den Rauchgasvorwärmer strömendem Heißwasser.Feed water evaporator system For waste heat systems, in which with the help a water circulation between a flue gas preheater and an expansion vessel Steam is generated, the circulating water of the flue gas preheater can be used more economically Use this way to distill the make-up water without using special fuel. The invention relates to such a feed water evaporator system with heating of the steam generator used to generate power by circulating through the Flue gas preheater flowing hot water.

Die Erfindung besteht darin, daß das aus dem Dampfentwickler zum Rauchgasvorwärmer zurücl<fließende heiße Wasser ganz oder teilweise zur Beheizung einer zusätzlichen Verdampferanlage benutzt wird. The invention is that the from the vapor generator to Flue gas preheater returns hot water, in whole or in part, for heating an additional evaporator system is used.

Das Schema der Zeichnung erläutert den Vorgang. a ist der Umwälzrauchgasvorwärmer, welcher z. B. hinter einem Zementdrehrohrofen eingebaut werden kann und das Wasser auf mehr als 2000 erwärmt. In dem Gefäß b findet eine Entspannung des heißen Wassers durch das vorgeschaltete Drosselventil c statt, wobei sich Dampf entwickelt, der durch die Hauptleitung d zu einer Turbine e abgeleitet wird. Diese Turbine ist in bekannter Weise durch die Leitung n an einen Kondensator angeschlossen. Bei der Entspannung bleibt der größere Teil des Wassers, allerdings mit niedrigerer Temperatur, in dem Behälter b zurück und wird beispielsweise mit I90° aus diesem mit Hilfe einer Umwälzpumpen zum Umwälzrauchgasvorwärmer zurückgeführt, in welchem die Wiedererwärmung auf über 2000 erfolgt. In der Rückleitung befindet sich nun ein Drosselventil g; außerdem ist an diese eine Abzweigleitung lt angeschlossen, durch die das Umwälzwasser ganz oder teilweise nach dem Rohwasserverdampfer i abgeführt wird. Dieser Heißwasserstrom gibt seine Wärme zum großen Teil im Verdampfer i zur Verdampfung des Rohwassers ab und kehrt dann zum Umwälzrauchgasvorwärmer zurück. Der Brüdendampf des Verdampfers geht teilweise, wie üblich, zunächst zu dem Rohwasservorwärmer bzw. Entkalker k, zum anderen Teil durch die Leitung I zu einem Kondensator zu m. Aus dem Kondensator m wird das gesamte Kondensat durch die Speisepumpe o und den Vorwärmer p zum Umwälzrauchgasvorwärmer a geführt. The scheme of the drawing explains the process. a is the circulating flue gas preheater, which z. B. can be installed behind a cement rotary kiln and the water heated to more than 2000. A relaxation of the hot water takes place in the vessel b held by the upstream throttle valve c, with steam developing, the is derived through the main line d to a turbine e. This turbine is in in a known manner connected to a capacitor by the line n. In the The greater part of the water remains relaxation, but at a lower temperature, in the container b and is for example with 190 ° from this with the help of a Circulation pumps returned to the circulation flue gas preheater, in which the reheating done on over 2000. In the return line there is now a throttle valve g; In addition, a branch line is connected to this through which the circulating water is wholly or partially discharged after the raw water evaporator i. This hot water stream gives most of its heat in the evaporator i to evaporate the raw water then returns to the recirculating flue gas preheater. The vapor from the evaporator goes partly, as usual, to the raw water preheater or decalcifier k, to the other part through the line I to a capacitor to m. From the capacitor m the entire condensate is converted into a circulating flue gas preheater through the feed pump o and the preheater p a led.

Bei diesem Kreislauf gelingt es, das gesamte Zusatzwasser praktisch verlustlos zu gewinnen. With this cycle it is possible to use practically all of the make-up water to win without loss.
