Abstract
Zariadenie pozostáva zo skupiny zvarovaných elementov a hrebeňovej steny privarenej v blízkosti ohybov na vodorovná časť rúrok, pričom v oblasti horného ohybu rúrok je tiež privarený závěsný element hrebeňového tvaru, ktorý je přepojený závěsným tiahLom cez oká na vlastný skříňový nosník uložený na vyčnievajúci dielec. Riešenia je možné využiť pri projektovaní parných kotlov s dvoj tahovou spalovacou komorouThe device consists of a group of welded elements and a ridge wall welded near the bends to the horizontal part of the pipes, while in the area of the upper bend of the pipes a ridge-shaped suspension element is also welded, which is connected by a suspension rod through the eyes to its own box beam placed on a protruding part. The solutions can be used in the design of steam boilers with a two-pass combustion chamber
Description
Vynález sa týká zariadenia na zavesenie rúrok prednej steny dodatkového tahu parných kotlov v oblasti vyšších teplĎt.The present invention relates to an apparatus for hanging pipes of the front wall of an additional draft of steam boilers in the region of higher temperatures.
Doterajšie spdsoby konštrukčných riešení sú rózne a vyžadujú predlženie rúrok prednej steny cez šikmý tah kotlá až nad vlastný strop dodatkového tahu, pričom musia byť rúrky ohýbané do tvaru mreže kvóli prúdeniu spalin. Iné druhy riešení zasa vyžadujú pre ich zavesenie mohutnú rámovú konštrukoiu s priečnymi nosníkmi. Tieto riešenia sú pracné, nakolko ich konštrukoia si vyžaduje zvýšenú potřebu materiálu a okrem toho narastajú rozměry prierezu šikmého tahu za účelom dodržania požadovanej rýchlosti spalin.Existing methods of construction are diverse and require the extension of the front wall tubes through the inclined draft of the boiler up to the actual ceiling of the additional draft, whereby the tubes must be bent in the shape of a lattice quota for flue gas flow. Other types of solutions require a massive frame construction with cross beams for their suspension. These solutions are laborious as their design requires increased material requirements and, in addition, the dimensions of the cross-sectional draft increase in order to maintain the desired flue gas velocity.
Vyššie uvedené nevýhody odstraňuje zariadenia na zavesenie rúrok prednej steny dodatkového ťahu parného kotlá podía vynálezu, ktorého podstatou je, že pozostáva zo skupiny zvarovaných elementov a hrebeňovej steny privarenej v blíkosti ohybov na vodorovné časť rúrok, pričom v oblasti horného ohybu rúrok je tiež privarený závěsný element hrebeňového tvaru, ktorý je přepojený závěsným tiahlom cez oká na vlastný skříňový nosník uložený na vyčnievajúci dielec.The aforementioned disadvantages are eliminated by the apparatus for hanging the front wall of the additional draft steam boiler according to the invention, which consists of a group of welded elements and a ridge wall welded in the vicinity of the bends to the horizontal part of the pipes. a ridge shape, which is connected by a pendant through the eyes to its own box girder mounted on a projecting part.
Návrh podía vynálezu podstatné zjednodušuje konštrukčné riešenie zariadenia na zavesenie rúrok prednej steny dodatkového tahu v oblasti vysokých teplót spalin až 500 °C a jej prepojenia s dalšou častou výhrevnej plochy. Zlepšia sa tiež tlakové poměry na straně páry, nakolko prepojenie výhřevných plóch parného kotlá je riešené priamo bez vstupných a výstupných komór a prepojovacieho potrubia. Zlepšia sa tiež funkčně a prevádzkové podmienky, čo sa prejaví aj vo zvýšeni spoločenského přínosu.The design according to the invention substantially simplifies the design of the device for hanging the tubes of the front wall of the additional draft in the region of high flue gas temperatures up to 500 ° C and its connection with another part of the heating surface. Pressure conditions on the steam side will also be improved, since the interconnection of the heating surfaces of the steam boiler is solved directly without the inlet and outlet chambers and the interconnecting piping. Functional and operational conditions will also improve, which will also translate into increased societal benefits.
Na přiložených výkresoch obr. 1 je znázorněná v náryse časť výhřevných plóch zariadenia so zavěšením a ich usporiadanie a na obr. 2 v náryse zariadenie na zavesenie rúrok prednej steny dodatkového ťahu parného kotlá, podía vynálezu.In the accompanying drawings, FIG. 1 shows a part of the heating surfaces of a suspension device and their arrangement, and FIG. 2 is a front elevational view of an apparatus for suspending the tubes of the front wall of an additional draft of a steam boiler according to the invention.
Pracovně médium prúdi cez rúrky 2 výhřevných plůch, ktoré sú umiestnené v spalovacom priestore 4 a sú zaústěné v spodnej časti do zbernej komory 2 a v hornej časti do zbernej komory _3·The working medium flows through the heating surface tubes 2, which are located in the combustion chamber 4 and are connected in the lower part to the collection chamber 2 and in the upper part into the collection chamber 3.
Rúrky 2 výhrevnej polochy tvoriace stenu spalovacieho priestoru 4 dodatkového ťahu sú v hornej časti v oblasti prvého ohybu privarené o závěsný dielec 6 hrebeňového tvaru, ktorý je spojený zvarom o spodně oká T_ a přepojený spojovacím tiahlom jj o horné oká Q, ktorých predlžená časť je nasunutá do skříňového nosníka 10, uloženého na vysunutých dielcoch 11, pričom usmernenie spalin je zabezpečené hrebeňovou stěnou 12, privarenou o vodorovnú časť rúrok výhrevnej plochy 2·The heating half tubes 2 forming the wall of the combustion chamber 4 of the additional draft are welded in the upper part in the region of the first bend to a ridge-shaped hinge piece 6 which is welded to the lower meshes T and connected by a connecting rod 11 into the box beam 10, supported on the extended parts 11, wherein the flue gas is guided by a ridge wall 12 welded to the horizontal part of the heating surface tubes 2;
Vynález je možné s výhodou využívat pri projektovaní u parných kotlov s dvoj tahovou spalovacou komorou.The invention can be advantageously used in the design of steam boilers with a two-pass combustion chamber.
