Product introduction

  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.





Safety

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

  Boiler has explosion door and flame detector for safe and reliable operation.

  comb plates are used as the sealing between both sides of boiler and tube bundle all use to avoid leakage of condensate and gas which is caused by refractory concrete sealing.

  air tightness test is done before leaving the factory to ensure no leakage of gas.

environmental protection

  Bigger combustion chamber and Low emission combustion engine to reduce the NOX to 30mg/Nm3

  Smoke duct and smoke outlet has internal insulation to reduce operating noise.

  Combustion chamber use full membrane water cooling wall structure, pressurized firing without smoke mixture.

energy conservation

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

  Combustion chamber use narrow distance tube membrane water cooling wall which has good air tightness, and reduce heat lost and increase boiler thermal efficiency.

  Inside of Inspection holes use high-alumina refractory and man hole cover sealing devices, it solved the high temperature of this part by using refractory brick

Convenience

  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.

longer lifespan

  Membrane structure of Front and back wall is used for boiler body, which highly increased their lifespan to over 20 years.

  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.

  flutter prevention fastener is used for high temperature part convection tube, which avoid bundle tube cracking problem.

  Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
