<p>The boiler for a Claus reactor has a steam generating zone within a pressure-tight mantle (14). A longitudinal tube bundle (18) acts as the heat exchanger through the steam zone, with both ends at tube bases (19) defining the steam zone. At least a further bundle (20) of shorter tubes has their outflow ends at the tube base and their inflow ends opening into a flow chamber (21) within the steam zone. A head piece (22), divided into sections, is at the tube base. A hot process gas from the combustion chamber (2) flows through the long tube bundle. A cooler gas from a catalyst stage (4) flows through the shorter tube bundle. The sections of each head piece are each linked to a tube bundle, to lead off condensed sulfur.</p> |
