摘要:
A steam generation boiler having a reaction chamber formed by a bottom portion in a lower portion, a roof portion at an upper portion, and walls extending vertically between the bottom portion and the roof portion. The walls include vertical end walls having a tapering wall section that tapers symmetrically with respect to its middle axis towards the bottom portion, in which (i) a first group of steam pipes in the tapering wall section including steam pipes on both sides of the middle axis, pass at an angle with respect to the middle axis in a wall plane of the tapering wall section, and from the wall plane into the reaction chamber, and (ii) a second group of steam pipes arranged to pass to the bottom portion along the wall plane.

The present invention relates to a steam generation boiler (10) comprising a bottom portion (12) and a roof portion (16) as well as walls (14) to extend vertically between the bottom portion and the roof portion, thus forming the reaction chamber (20) of the steam generation boiler, the walls (14) of which reaction chamber embody a structure comprising of steam generator pipes (30), and which steam generation boiler (10) comprises in its lower part at least one wall section (14.31) tapering towards the bottom portion (12). A first group (30.1) of steam pipes in said tapering wall section (14.31) is arranged to pass from the wall plane (Y-Z) into the reaction chamber (20) and extend from the wall plane (Y-Z) to the bottom portion (12) of the steam generation boiler on the side of the reaction chamber (20) forming a wall (11) in the reaction chamber (20), and a second group (30.2) of steam pipes is arranged to pass to the bottom portion along the wall plane (Y-Z).

The present invention concerns a processing furnace used by the oil industry to heat feedstocks that are to the treated thermally, which is provided with bi-pivotal support columns (4) to carry the radiation exchange tubes (10) which form the coil of radiation exchange tubes. The support columns (4) are provided with a lower bearing means and an upper bearing means, which pivot, respectively, on a lower support means (6) and an upper guide means (8), in such a way that all the stresses from the support means (4) and the radiation exchange tubes (10) are transmitted to the base (12), causing no thermal stress from bending momentum to be transmitted to the base (12) of the furnace.
摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung von überhitztem Dampf mittels der im Kessel (3) einer Verbrennungsanlage (2; 201) erzeugten Wärme, wobei vorüberhitzter Dampf einem Endüberhitzer (22) zugeführt wird, welcher in Form von mehreren Endüberhitzerrohren (24) vorliegt, durch welche der vorüberhitzte Dampf geleitet und dabei endüberhitzt wird, und die Endüberhitzerrohre (24, 24', 24") mindestens teilweise in mindestens einem Hohlraum (26, 26`, 26") angeordnet sind, der im Innern eines Wandelements (28) des Kessels (3) und/oder eines im Kessel (3) angeordneten Schotts (30) ausgebildet und kesselseitig mindestens teilweise durch eine Feuerfestmaterialschicht (34) abgeschlossen ist und von dem bei der Verbrennung freigesetzten Rauchgas überströmt wird. Erfindungsgemäss wird der Hohlraum (26) von einem Sekundärmedium durchströmt, welches dabei über Wärmeübertragung vom Rauchgas über die Feuerfestmaterialschicht (34) erwärmt wird. Das derart erwärmte Sekundärmedium wird über eine Sekundärmediumzuführleitung (44) einem Sekundärwärmetauscher (42) zugeführt.
摘要:
A furnace tube arrangement for a steam generator is described. A plurality of furnace tubes disposed longitudinally form a generally planar wall structure into which burner throats are let at least two longitudinally spaced levels in familiar manner. Burner throats at the respective levels are so disposed that a vertical mid-line of each throat at a first level is laterally offset from a vertical mid line of a corresponding throat at a second level.
