Definitions

• the invention relates to a refractory lining in the transition section of a carburetor to the waste heat boiler with brackets for fastening refractory shaped bricks.
• the transition from the carburetor to the waste heat boiler is flowed through both by the hot synthesis gas and by hot slag.
• the temperatures in this transition section are over 1400 ° C.
• the transition between the reactor vessel and the synthesis gas cooler is lined with a refractory delivery made of molded bricks from a reactor vessel supplied by the applicant for the Ruhr synthesis gas plant (SAR) of Ruhrchemie in Oberhausen-Holten with a subsequent waste heat boiler of a synthesis gas cooler.
• SAR Ruhr synthesis gas plant
• the upper shaped stones are each placed in a ring on cast brackets, which are attached one above the other at the nozzle end of the carburetor and at the nozzle end of the synthesis gas cooler.
• the shaped stones in the area of the cooling tube cage are on circumferential tube lugs
• REPLACEMENT BLA ⁇ (RULE 26) Transition from vertical cooling pipes to the horizontal cooling pipe wall.
• the thermal stresses caused by high temperatures and the resulting ff material movements are directly on the high-pressure parts on the water side , for example the tubes of the cooling tube cage, transferred; Furthermore, the entire weight of the stones weighs on the supports. Furthermore, the upper fixed points (brackets) at the transition between the two vessels are uncooled and are subject to increasing overheating as the ff material wears down.
• the object of the invention is therefore to design the refractory lining in the transition section between the reactor and the synthesis gas cooler in such a way that the stresses in the ff material are reduced, the dead weight of the stones is distributed over various conditions, a compensation of the relative movements between the ff stones and the Mounts done, rugged
• brackets are not attached to water-carrying components (boiler pipes) and the so-called main claw is protected from overheating by additional cooling.
• the refractory area consists of three different, side by side stone layers in the uncooled nozzle as well as different Special shaped stones, shoulder shaped stones and normal stones, which are matched to the conditions of temperature, wear, internal and external pressure and service life.
• the refractory stone lining is supported on the connection piece and on the cooling tube cage of the synthesis gas cooler by a stone holding system, which consists of consoles arranged one above the other in the area of the cooling tube
• the supports for the ff-stones are distributed on different levels in order to distribute the stone weights and to keep local stresses low
• the stone brackets are on the webs between the water-side high-pressure parts (boiler pipes)
• REPLACEMENT3LATT (RULE26) - Design of a drip nose at the lower exit of the cooling tube cage so that the slag does not crawl along the horizontal wall and slag this as well as the bulkhead walls and the tube cage.
• Fig. 2 shows a section through the ff material at the transition from the carburetor to the waste heat boiler.
• an ff lining which consists of a number of normal and shaped stones, is introduced in the transition section between the carburetor (1) and the waste heat boiler (4).
• the transition section consists on the outside of the uncooled carburetor socket (2) and the cooled pipe cage (5) in the upper part of the waste heat boiler (3, 4).
• the ff lining is supported in the tube cage (5) by consoles (9) arranged one above the other, which are welded to the webs (tube-web-tube welding) of the tube cage (5).
• expansion joints (27) are provided below each of the brackets (9), while an annular, ceramic fiberboard (6) is inserted between the ff lining at the transition to the nozzle (2).
• An ff ramming compound (24) or the like is applied between the upper part of the tube cage (5) and the cooling system (10, 11, 12).
• FIG. 2 shows the structure of the ff lining in the transition section from the carburetor (2) and inlet connection (3) of the waste heat boiler (4).
• the ff-lining is held by claws (8), which are protected from overheating by a cooling system (10, 11, 12).
• a layer of shaped blocks (13, 14) are first placed on the claws (8), and the shaped blocks (18, 19) are used towards the center, circular segments of a horizontally arranged ceramic fiberboard (6) and a vertically arranged fiberboard (28) is inserted between the stones (19) and (14). Above the stones (15, 16) are arranged in one position and above the stones (17). Medium (20) and outer molded blocks (21) and a ceramic mat (22) are also used for insulation.
