Industry Low Pressure Natural Gas Mobile Steam Boiler For Parboiling Rice,Rice Mill
WNS series oil/gas fired boiler adopts horizontal three-pass wet-back structure,large corrugated furnace and patented thread pipe technology,equipped with international first-level brand burners and valve groups,and independently developed high-matching PLC control system to realize muitiple linkages.The lock protection function protects the equipment running safely.
It is full-automatic oil(gas) fired packaged steam boiler; adopting horizontal internal micro positive pressure combustion, full wetback design, high efficiency spirally corrugated tubes, fuel economizer and reasonable insulation package; the thermal efficiency can reach more than 90%. Its novel design, rational structural and nice performance achieved perfect quality and nice performance.
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.
Performance advantage
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.
