coal fired hot water boilers, ZOZEN thermal oil heaters have temperature and pressure control system to realize stable operation

Facing the challenges of 2020, Wuxi Zozen Boilers Co., Ltd. has made great progress. In July, ZOZEN's Wuwei Yili project team, with wonderful performance on project construction and management in the second quarter, was awarded "Excellent Project Team". ZOZEN will continue to provide high-quality heat supply equipment for Yili Group's demonstrative project of green production and intelligent manufacturing.
The WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation, coal fired hot water boilers.
coal fired hot water boilers, Designed to wrap the whole furnace body for heat preservation. There are no heat transfer supports between the furnace body and the outside surface. The appearance is mirror polished stainless steel with a protective coating. After the boiler is installed, remove the coating and show the mirror polished stainless steel appearance. Advantages: a good-looking appearance, low temperature of surface, low heat dissipation.
coal fired hot water boilers, In terms of welding technology, ZOZEN longitudinal and circumferential seam welding adopts advanced automatic submerged arc welding technology, and 100% X-ray detection is carried out on the welding seam to ensure the welding quality. The welding of the smoke tube and tube sheet adopts pre-expansion first to eliminate the gap between the tube and tube sheet, and then adopts the automatic argon arc welding technology, which can effectively eliminate the stress and extend the service life of the 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.
All boilers are subject to damage if proper water treatment procedures are not followed. This is an important consideration both during operation and when the boiler is idle. To avoid damage and costly repairs, monitor water chemistry routinely and ensure that you are supplying your boiler with soft water at all times.
