Definitions

  • a walled bond for heating hues of a horizontal chamber coke oven which comprises header Walls consisting of three block sections in each individual course with the central block sections being formed as a frame shaped block and with the courses being alternately arranged as follows.
  • One course comprises a central block section and two head blocks each adjacent a respective opposite end thereof, the head blocks extending through the adjacent stretcher walls on each side to the exterior surface of the stretcher wall which is in contact with the coal.
  • the header course lying above or below this course also includes a central block section which is shorter than the central block section of the first course, so that end blocks engaging each end of it overlap the central block section of the first header course, with their outer end faces either lying flat against the continuous stretcher walls or engaged into recesses formed in such stretcher walls.
  • the width of the head blocks and end blocks adjacent the stretcher walls is advantageously made smaller than the width of the central block sections, or the maximum thickness of the header wall in the central portion, the head blocks and end blocks being substantially uniformly tapered from the maximum width at the location where they abut the central block section to the ends thereof adjacent the stretcher walls.
  • This obviates abrupt transition sections in the header wall, such as characteristic of the use of T-shaped'blocks, for example.
  • a favorable ratioof coal-contacted area to heater area is maintained.
  • the gas space for radiation of heat between the header walls, directly at the stretcher walls is increased, so that heated wall temperature is higher by at least 30 C. than if the header wall had the same thickness at the stretcher walls as it has at its central portion.
  • central block sections in the form of block sections having substantially parallel upper and lower surfaces and formed with a vertically extending opening, which opens completely through the upper and lower surfaces, makes it possible to use the cavities of these block sections to form a continuous vertical duct for gas conduction and air conduction and also makes it possible to employ the header walls as an ideal stepped heating arrangement for the coke chamber.
  • a very great advantage is that the header walls will withstand great or intense heating and unusually large thermal stresses because one-piece central block sections provided in every alternate course insure the static cohesion of the header courses and hence of the heating walls.
  • the central block sections of the three-section header courses are designed as frame block sections having openings extending completely therethrough between their upper and lower surfaces.
  • An additional advantage lies in the symmetrical arrangement and ability to withstand stress of the header walls, and the non-symmetrical configuration and arrangement provided by the hammerhead or T-shaped blocks of prior art constructions is avoided.
  • abruptly or sharply recessed parts are substantially avoided in the connection of the header walls to the heating walls so that the irregular stresses which are likely to occur at such points are avoided.
  • a further advantage is the easy movability and transportability of the blocks of the three part header course construction, and in particular of the central block sections which may be formed in one or several parts.
  • a three-block or three-section design of the header courses, as well as the design of the head blocks as simple heads a substantial reduction of the dimensions and the weight of the individual header blocks is achieved.
  • the individual elements of the header courses are relatively easy to transport even for ovens having relatively great spans and relatively great heights, so that no special transportation and loading device are required for the erection of the header walls.
  • the header course blocks of the invention can be transported and stacked with less danger of breakage than can angle blocks, such as hammer heads or T blocks, which, because of their numerous sharp corners, edges and recesses have a tendency to break readily.
  • the design of the central block sections of the three-section header courses as frame block sections provides that at least the same strength as obtainable with one-piece blocks extending the full length of the header can be obtained even at temperatures of above 1000 C.
  • the invention arrangement provides the simplest possible manner for arranging vertical channels in the interior of the headers, such channels being indispensible for stepwise heating without which uniform heating of relatively high ovens is not possible.
  • the head or end blocks of three-part header courses include T or hammer head blocks projecting into the stretcher wall.
  • the width of the head or end blocks is the same as that of the central block section to directly at the surface of the stretcher wall, after which the head or end blocks have their cross sections sharply reduced for engagement into the stretcher wall.
  • the header courses are subjected to stresses which, in practice, lead to breaking at the angular projections bonded into the stretcher walls.
  • Such rectangularly recessed masonry parts are avoided in the present invention by providing that the transition between the greater width of the central block sections and the end width of the head or end blocks is uniform and comprises gradually tapering peripheral areas within
  • the formation of a central header block section as a frame-shaped block section also offers the possibility of clamping the central block section securely to the outer head blocks. It is true that large frame-shaped blocks often become warped when they are fired, and hence they may not stack evenly.
  • the present invention overcomes this difficulty, since the courses lying over or under such one piece central header block section are fitted together from smaller edge blocks which again form, with end blocks, a frame'shaped, and somewhat shorter, central block section.
  • the end blocks of the course employing the center block sections made up of a plurality of individual smaller edge blocks are not engaged into the stretcher walls but are applied to lie flat against these walls or engaged into relatively shallow recesses formed in the stretcher walls.
  • a further object of the invention is to provide an improved heating wall construction which includes a block course comprising a central header block section with head blocks engaging each end thereof and which engage into adjacent stretcher block walls, and a second course comprising a central header block section formed by spaced edge blocks which engage into end blocks which are made to rest either flush against the interior stretcher walls or in recesses formed therein.
  • a further object of the invention is to provide a heating wall construction in which the various center block sections, head blocks and end blocks are fitted together by projecting rib and groove configurations.
