WNS series gas/oil fired industrial steam boiler use international most mature three-pass all wet back structure,safety and reliable .Use waveform furnace ,strengthens the disturbance of the smoke and increases the radiation heat transfer area ;increases the stiffness of the furnace and effectively reduces the thermal stress of the furnace;enhance heat transfer and promote the combustion of fuel in the furnace.The heating surface is arranged symmetrically with solid structural strength and reasonable water circulation .Boiler up part inside has full water capacity ,big steam space and good quality steam .During procession ,the water level fluctuation is small .Big distance between two ends boiler ,big diameter of tubes ,all of these ensure good natural circulation. Steam boiler with very small heat loss because of unique furnace and flue gas thermal surface design .
When industrial steam boiler goes out of the factory, it is composed of three parts: the main boiler, the chimney and the pipeline system. The main body and the chimney have been manufactured in the factory, and the supporting pipeline valves and instruments of the main boiler have been installed randomly, and then transported to the site to assemble the main body and the chimney.On the spot connect the air source, power supply and water pipeline to start the test.Greatly shorten the installation cycle, and can guarantee the quality of boiler.
Advanced three pass wet back design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.
Advanced manufacturing equipment endows Safe and reliable property:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.
Large boiler proper heating area:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.
High efficiency 98%:with threaded pipe and high effective insulation materials and econoizer, increasing the heat transfer and improve boiler thermal efficiency.
PLC intelligent controller:boiler control system suitable for high temperature, high humidity environment of long-term operation.
High standard: strictly in accordance with Chinese national norms and standards of production, all boiler pressure parts are of high quality steel.
Gas/oil fired steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarket, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
