High Efficiency Fire Tube Steam Boilers

Features of WNS horizontal gas fired Steam Boilers  Devotion Steam Boilers are constructed availing internationally tried and tested design of three pass, wet back structure to deliver higher safety and reliability  The specially-desgined large combustion room enlarges the heating area by hearth radiation while lessens the boiler size and reduces NOx emission;  The corrugated hearth makes it a safer boiler for users.  The threaded smoke tubes improve heat transfer, thus increase the boiler’s thermal efficiency;  Multi levels sealing applied on front and rear smokeboxes, no smoke leakage;  Lager steam space, fine quality steam;  High-efficient insulation materials, low boiler surface temperature. The heat dissipation loss may be ignored;  Boiler control system can run for a long time under high temperature and humidity.  Multi-level interlock protections available like water level, steam pressure, gas pressure and so on.  Devotion boilers are manufactured and tested in compliance with national standards. All pressurized parts are made from high quality steels from well-known steel plants.  Each boiler must undertake a series inspection and test before delivered to the user, such as Non-destructive test and hydraulic tests.  All components and auxiliary equipments like burners, pumps, water level gauge, safety valves are supplied by renowned brands.  Easy maintenance with man hole and hand holes.  A patented economizer (optional) can save 15% fuel and reduce noises. Application for Devotion Steam Boilers  Industrial users: pharmacy, papermaking, tobacco, textile printing and garment industries etc  Civil users: catering, laundry room, disinfection(hospital）, sauna etc  Through vapor-water heat exchanger, the boilers can heat the water inside heating system for air conditioner, radiators and floor heating etc  Provide power to LiBr absorption refrigerator with pressure P=0.6-0.8Mpa
