Air pollution reducing chimney - with chromium nickel steel lining and low heat conductive space filling

摘要

The chimney is designed to meet the standards demanded in connection with a heat loading of 40,000 kcal/h to 3 Gcal/h, paying regard to legislation relating to air pollution above heating installations. The chimney is conical or pyramid-shaped in form interior space can be effected with an inside cladding of chromium-nickel steel or similar. Here the part remaining clear between the external sheath and the sheet steel is filled with a material with a low degree of heat conductivity. The sheets for the interior chimney cladding can be assembled in one or two-meter lengths of fireclay pipes which lead to the connection with the fireplace.
