Description

Regulowanie temperatury pary prze¬ grzanej zapomoca wtryskiwania wody jest juz znane, podobniez jak i zapomoca mie¬ szania z para nasycona. Pierwszy z tych sposobów posiada w wykonaniu dotychcza- sowem te niedogodnosc, ze wymaga wtry¬ skiwania i nagrzewania znacznych ilosci wody, gdy tymczasem mala tylko jej ilosc zostaje odparowana. Sposób drugi zdradza ten znowu brak, ze wymiana ciepla pomie¬ dzy para przegrzana a woda albo zawarte- mi w parze nasyconej drobniutkiemi kro¬ pelkami wody jest nader wadliwa, wskutek czego powstaje para przegrzana o tempe¬ raturze bardzo niejednostajnej, nie bedaca ponadto wolna od drobniutkich czasteczek wody. Ponadto sposób ten wymaga, wobec wlasnie bardzo niepomyslnych warunków 11 przenoszenia ciepla, wielkich przestrzeni do wymiany tegoz.Wynalazek niniejszy usuwa pomienione braki, uskuteczniajac w odpowiednim zbior¬ niku wymiane ciepla pomiedzy woda i przegrzana para za posrednictwem cial o wielkiej powierzchni, jak np. kul metalo¬ wych, pierscieni lub tym podobnych. Wy¬ miana ciepla zachodzi przytem w sposób tak intensywny, ze wystarcza przestrzen bardzo ograniczona, a temperatura i wla¬ snosci pary zostaja po wyrównaniu nadal jednostajne.Jedna z mozliwych form wykonania wy¬ nalazku wyobraza zalaczony rysunek. Do przewodu a, przez który plynie para prze¬ grzana, wtryskujemy rurka b wode w sta¬ nie mozliwie rozdrobnionym.Na powierzchni wprowadzonych do przewodu, w jednym lub kilku ukladach, cial^c, w rodzaju np. kulek, obraczek meta¬ lowych lub tym podobnych, wytwarza sie cienka warstewka wodna o wielkiej po¬ wierzchni, a jednoczesnie powstaje, wsku¬ tek zwezenia przekroju, znaczne powiek¬ szenie szybkosci pary, W czesci d rury znajduje sie jedynie para przegrzana, albowiem uklad c w ta¬ kich wymiarach jest utrzymany, aby wszystka woda odparowala. Pare te odcia¬ gamy przez kolano e, a przez zawór / u- skutecznia sie odwodnienie przy puszczaniu aparatu w ruch.Celem samoczynnej pracy urzadzenia nastawiamy doplyw wody odpowiednio do wysokosci temperatury pary w przewodzie e, umieszczajac w nim miarkownik tem¬ peratury o budowie znanej. PL PLThe regulation of the temperature of superheated steam by injecting water is already known, as is mixing with saturated steam. The former method hitherto has the disadvantage that it requires the injection and heating of large amounts of water, while only a small amount is evaporated. The second method reveals the lack of the fact that the heat exchange between the superheated steam and the water or the water contained in the steam saturated with tiny water droplets is very defective, as a result of which superheated steam with a temperature very uneven and not free from tiny water particles. Moreover, this method requires, in view of the very unsuccessful conditions of heat transfer, a large space for exchanging it. The present invention overcomes the above-mentioned deficiencies by effecting, in a suitable vessel, heat exchange between water and superheated steam via large-surface bodies, such as balls. metal, rings or the like. The heat exchange also takes place so intensely that the space is very limited and the temperature and steam properties remain uniform after equalization. One possible embodiment of the invention is illustrated in the attached drawing. Into the conduit, through which the superheated steam flows, the tube b is injected with water in a finely divided state. On the surface introduced into the conduit, in one or more arrangements, bodies, such as balls, metal rings or and the like, a thin water film with a large surface is produced, and at the same time, due to the narrowing of the cross-section, a significant increase in the speed of the steam is created. In part d of the pipe there is only superheated steam, because the system of such dimensions is maintained that all the water evaporates. Some of these are stretched through the elbow, and through the valve / the dehydration is effective when the apparatus is set in motion. . PL PL
