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, super heater is arranged at convection tube bundle. 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.

|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.|
06Manholes & Check door
The manholes are arranged at the two ends of upper and lower drums , and check door is set a rear part of boiler.
These openings make users easy for entering inside doing maintenance and cleaning work : prevent vaporization
|The boiler water circulation adopts enforced circulation to secure each heat absorbing part can get efficient cooling and prevent vaporization.|
|Adopt high-class aluminium silicate fibre . Use refractory mortar to keep the furnace temperature under 45'and control heat loss effecient|
