Product Name: 500-6000kg/H Fire Tube 3 Pass Wet Back Type Oil Fired Steam Boiler Model NO.: WNS Usage: Industrial Burning Style: Chamber Combustion Boiler Manufacturing Level: B Pressure: High Pressure Drum Placement: Horizontal Boiler Water Circulation: Natural Circulation Media: Steam and Water Structure: Fire Tube Installation: Packaged Boiler Fuel: Oil-Fired Function: Steam Boilers Place Style: Horizontal Gas Flow Type: Fire Tube Trademark: T-SUN Transport Package: Wooden Case Specification: CE, SGS, TUV, ASMI Origin: Shanghai HS Code: 8402190000 Product Description 1. FEATURESThe brand name is T-SUN, made in Shanghai.88-94% thermal efficiencyHorizontal Wet Back 3 Pass Fire Tube Shell Boiler StructureApplications include: Steam for tanks, reactors, distillations, autoclaves, dyestuffs, food products, cosmetics, paraffins, glues, steam jacketed kettles, sterilizers, cosmetics, pipe tracing and humidification.Built to China Boiler and Pressure Vessel Codes- "Safety Technical and Supervisory Specification of Steam Boiler"(edition 96), JB/T10094-2002 "General Technical Conditions of Industrial Boiler", GB/T16508-1996 "Pressure Parts Strength Calculation of Boiler Shell" and GB50273-1998 "Code of Construction and Acceptance of Industrial Boiler"Spirally corrugated tube increases the strength and also meets the needs of heat expansion of each part.Butt joint X-ray test ensures the welding quality reaches the national requirements.The big water volume provides better load adaptability. Properly designed boiler inner device ensures the steam and water rate less than 3%.High and low water alarm uses stainless steel electrode and Teflon insulating material. It is inserted vertically.The hinged front and back smoke box can be opened easily for maintenance.Low Water Cut-off/Level Control automatically maintains proper water level, shutting off the boiler when water supply in the boiler drops below a safe operating level.Integral Power ContactorsMagnetic contactors for energizing the boiler elements. Integrally mounted in the control unit.Operating Pressure Control resets automatically to maintain preset pressure within boiler.2. SAFETY FEATURESReal-time monitoring of water level: Electronic water-level detecting deviceWater shortage protection: The combustion control system power will be cut off when there is water shortage along with alarm.Leakage protection: The power will be cut off when there is leakage detected by the control system.Over pressure protection: When the pressure is over the preset value, the combustion control system power will be cut off along with alarm.Steam Safety Valve automatically opens to reduce pressure should excessive steam cause pressure build-up.Steam Pressure Gauge allows visual observation of steam pressure over full range.Manual Reset Pressure Control provides high limit pressure cut-out with manual reset.Complete gas manifolds and protection system for gas boiler: Strainer, pressure regulating valve and magnetic valveFlue gas monitoring device can detect the flue gas temperature automatically.3.
