As an industrial boiler manufacturing company with more than 30 years of development history, ZOZEN today's achievements are inseparable from its sustainable development concept.  Recently, ZOZEN reached cooperation with Libbey Inc., the global glassware industry giant. The two sides shared the same development concepts and became friendly and trustworthy partners, usage of coal in boiler.

In the process of smelting molten steel, pouring steel ingots, and producing finished castings, a large amount of steam is consumed. The superheated steam generated by the boiler provides the required thermal energy for its process. Through open bidding, ZOZEN stood out among many boiler manufacturing enterprises with its own technical advantages and quality assurance, and provided China Second Heavy Machinery Group Corporation with a large superheated steam boiler, usage of coal in boiler.

In the production process of starch from cassava as raw material, the steps of bleaching, concentration, dehydration, and drying all need the support of heat provided by steam boilers. General Starch CO.,LTD is one of Thailand's leading modified tapioca starch manufacturers, it selected ZOZEN SZS series condensing gas-fired steam boilers, which feature high efficiency, eco-friendly and energy-saving. The chamber is larger so that the radiation heating surface is more sufficient to improve the heat efficiency to 98%. And the automatic operation makes the boilers easy and safe to operate.

Scaling, abrasion, burning front arch and feeding hopper are common problems of biomass-fired boilers, ZOZEN increased height of furnace, fastening the speed of stoker, input ash blowing unit at convection area, and automatic ash cleaning system at the bottom of stoker, so the above problems are all solved, it reduced much maintaining personnel’s work. Advantages: Make biomass-fired boiler a clean and neat working environment.

usage of coal in boiler, ZOZEN has set up a total of seven process stopping points throughout the production process, which are strictly controlled by different engineers, independent of each other and supervised each other, so that problems can be found and solved in time. If any workpiece is unqualified, it cannot enter the next process, which is the quality control of the entire production process of ZOZEN.

usage of coal in boiler, Quality and service are the foundation of the company. Over the years, ZOZEN has won the recognition and trust of many enterprise users due to the high product quality guarantee the intimate service provided to customers in the sales and after-sales links.
