Product Detail Product introduction

  The SZS series boilers are double drums, longitudinal and longitudinal, and chamber-fired D-type arrangements. The right side is the furnace chamber and the left side is the convection tube bundle. The movable supports in the middle and the two ends of the lower drum are fixed on the body chassis, and Ensure that the entire boiler expands toward both ends. The furnace chamber is surrounded by a narrow-spaced tubular membrane water wall. The membrane water wall on the left side of the furnace chamber completely seals the furnace chamber from the convection tube bundles. The rear of the convection tube bundle area is a delaminated staggered structure, and the front is a parallel column structure. The furnace is burning. The generated flue gas enters the combustion chamber and convection zone from the smoke outlet at the tail of the furnace, and then turns from the left front of the boiler into spiral finned tube economizers and condensers. Finally, it enters the flue and enters the chimney to the atmosphere.
