Introduction
WNS type steam boiler wet back type three return all the corrugated furnace, threaded smoke tube, heat has good scalabiity.The tube plate and the cylinder body adopts the flanged connection structure, the main body of weld butt structure, all adopt the automatic submerged arc welding. Heating area is abundant, large hearth structure, micro positive pressure combustion,combustion heat load is low, less emissions of harmful substances, many boiler combustion chamber design is reasonable,fully adapt to city gas, natural gas,light diesel oil, heavy oil and other fuels, fuel in the hearth of the micro positive pressure combustion, burning completely, less pollutants from flue gas, boiler flue gas blackness, the blackness of the smoke and dust concentration and noise technical indicators were better than the national a class area standards.
Boiler Feature
Performance advantage
1. Boiler design
Horizontal internal combustion three return journey full wet back design, 100% corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tubeplate butt joint, lowest stress, more reliable quality.
2, large diameter corrugated furnace
The boiler combustion chamber is composed of a large diameter full ripple furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.
3. Sufficient heat
The heating area of the boiler is designed to be more than 25 square meters/ton, fully absorbing effective heat, low smoke exhaust temperature, small heat loss, ensuring sufficient output and high efficiency.
4. Steam quality
Pot shell diameter, large water capacity, strong adaptability to load changes, stable output, steam space volume, soda interface and steam outlet net distance is high, low steam humidity.
5. Multi-functional safety and explosion protection device
The back plate of the boiler is equipped with the explosion-proof device which is connected with the furnace to prevent the high energy of the discharge moment when the fuel is violently deflated in the furnace, and it can automatically reset. Meanwhile, it has the function of the fire-viewing mirror and the maintenance channel. It makes use of the adjustment of the burning flame in operation, and makes the furnace inspection and maintenance convenient.
SAFETY FEATURES
Real-time monitoring of water level: Electronic water-level detecting device
Water 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 valve
Flue gas monitoring device can detect the flue gas temperature automatically.
