Horizontal Gas Fired Steam Boilers

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

Devotion Gas Steam Boilers Structure

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 equipment 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.

Tips about selecting Steam Boilers model

• Unless space of boiler room is limited, horizontal boilers rather than vertical boilers are recommended because horizontal boilers have higher efficiency.
• In case steam pressure is above 1.6Mpa, water tube boilers or water- fire tube boilers are recommended instead of Fire Tube Boilers.
• Should only steam temperature matter while no requirements for pressure, it is better to choose superheated Steam Boilers.
• For industrial users, as per requirements of production process, certain margin should be allowed besides resistance loss of pipeline and boiler room.

Notes:

1. The rated pressure of each model of boiler is available at 0.4, 0.7, 1.0, 1.6, 2.45Mpa
2. The low heating values of different fuels are calculated as follows:

     3. Parameters in the above sheet shall be adjusted subject to changes of heating values or chemical composition.
