Definitions

  • the front and side walls of the chamber B are also lined with finned tubes 83 so that the chamber B is lined with a substantially continuous metallic wall, the inner face of which is exposed to radiant heat.
  • a system for recovering chemical and generating steam from the black liquor of wood pulp mills which system comprises a smelter furnace into which the black liquor is sprayed, a chamber thereabove successively arranged with respect thereto as to flow of combustion products and having a discharge opening in the upper chamber portion remote from the furnace, and a boiler successively arranged with respect to the chamber and having a tube bank which receives the combustion products as same pass out of said chamber opening, the combination of heat-absorbing superheater tubes within said chamber connected with said boiler and there extending vertically downward toward said furnace from the chambers upper portion whereby the combustion products passing upwardly through the chamber will have substantially parallel flow with respect to those tubes, said superheater tubes being organized into a unitary superheater assemblage comprising spaced rows of alternately long and short tube portions serially connected for boiler steam flow therethrough with the long tube portions extending a substantial distance further down in the chamber than do the short tube por-v tions and thus being more widely spaced apart at their lower ends than are adjacent rows of long and short tube
