Definitions

  • the above object is achieved with, a boiler as presented and characterized in the main claim.
  • the advantage of disposing a downwardly sloping, reasonably smoke-tight radiation shield in the manner described is that the combustible gasses, which are given off mainly in the area covered by the radiation shield, rise up under this, are mixed with secondary air which is fed to this area, and ignited, the reason being that the space under the radiation shield has a high temperature (both a high air temperature as well as a high radiation temperature) before the mixture of secondary air and combustible gasses reaches forward to the relatively narrow burning-out opening rearmost in the boiler.
  • the invention can be characterized in the manner presented in claim 4.
  • the advantage of the loosely disposed but secured elements is that it is not only easy to undertake replacement, when this is required after a certain period of operation, but also possible in a simple and quick manner to change the size of the radiation shield by the removal or insertion of some of the ceramic elements.
  • the latter can be advantageous when changing between types of fuels having different gas contents and varying ignition temperatures for the gasses given off.
  • the invention has been made in connection with the work with a new suspended arch which is described by the same inventor in a patent application submitted together with the present description, and which can also be expediently formed with the use of the non-supporting construction of shaped, ceramic elements which are suspended in a supporting structure as described above.
  • the radiation shield 3 is built up of suitably-shaped ceramic elements 4 which comprise a non-selfsupporting shield which is supported by a number of parallel tubes 5 sloping upwards from the back wall 7 of the firing chamber 11, where the inside of each tube 5 in the supporting structure is in open connection with the water chamber in the back wall if the boiler.
  • the tubes 5 which support the radiation shield in a cor responding manner are each connected to the water chamber in the front wall of the boiler.
