SZS Series Boiler is double drums, longitudinal arranged, "D" type chamber structure. Furnace is on right side and convection tube bundle is on the left. The body is fixed on the basement by middle and both end flexible supports and make the boiler to expand horizontally to sideways. Around furnace is membrane water cooling tube wall. Furnace and tube bundle is totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, bundle area, and then from left front part enters spiral fin coil economizer and condenser, finally discharged to atmosphere through chimney.

Feature

1.Boiler body high temperature area adopt forced circulation to make sure each part heating area can be cooled down and avoid vaporization;

2.Good quality alumina silicate fiber and fire clay insulation is used, boiler body temperature is controlled below 45°C, to reduce heat lost.

3.Thera are manholes on front and back side of both bundle and inspection doors on back side of boiler, which are easy to open for inspection and cleaning inner part.

4.The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
