WNS series steam boilers are designed with a horizontal wet-back three-return fuel (gas) structure. The fuel burns in the furnace to generate high-temperature flue gas, which is discharged into the atmosphere through the return combustion chamber → first convection tube bundle → front smoke box → second convection tube bundle → rear smoke box → economizer (or condenser) → chimney. The corrugated furnace is used in the design of the furnace, which reduces the rigidity of the furnace and reduces the thermal deformation stress. Spring-loaded explosion-proof doors and inspection doors are installed in the return combustion chamber for easy maintenance and explosion-proofing. There are manholes on the furnace body of the horizontal boiler, which is convenient for the internal maintenance of the furnace shell. The smoke pipe adopts threaded smoke pipe, which makes the flue gas disturb in the smoke pipe, enhances the heat exchange effect and improves the thermal efficiency. The front and rear smoke boxes adopt a hinged light structure, which is convenient for opening and closing maintenance.
