Henan Kailun Chemical Co., Ltd., set up in 1953, is always committed to the research, development and production of new-type, highly-efficient and eco-friendly rubber chemicals and auxiliaries for all-steal radial ply tyre. The company is also a leading and demonstration enterprise of energy saving, emission reduction, scientific and technological innovation in the rubber chemical industry in Henan Province. There is a large amount of steam consumed during the production of rubber chemicals, which puts forward high requirements for the output capacity and steam quality of industrial boiler equipment. After a specific investigation on the domestic steam boiler suppliers, Henan Kailun Chemical Co., Ltd. finally decided to purchase the WNS series horizontal gas-fired steam boiler produced by ZOZEN in order to meet its increasing production demands.
ZOZEN's WNS series two-pass horizontal gas-fired steam boiler adopts large-diameter waveform strove furnace to transfer the radiant heat via furnace wall, which effectively improves the heat transfer efficiency. Meanwhile, ZOZEN's WNS series steam boiler also adopts thread smoke tube which acquires the national patent to strengthen the convective heat transfer, so as to greatly improve boiler's thermal efficiency. In addition, ZOZEN's WNS series boiler is equipped with the economizer and condenser at the end of flue gas duct to effectively reduce the heat loss caused by the emission of exhaust gas and to save energy. In general, ZOZEN's WNS series gas-fired steam boiler with sufficient output and high thermal efficiency (over 98%) is a salable product with good energy-saving and eco-friendly performance.
