With the increasing environmental problems, environment-friendly gas-fired boilers have attracted more and more attention. In response to the situation, ZOZEN launched the WNS series gas-fired boiler product, which not only had outstanding environmental performance, but also helped many enterprises realize the goal of energy conservation. ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion. Through the commissioning of experienced ZOZEN technicians, the burner can achieve a good combustion state. In addition, the boiler has a large diameter furnace, which can further improve the combustion efficiency.
Among many industrial boiler products, Bintou Thermal Power selected ZOZEN SZS series gas-fired steam boiler for peak shaving. This series of boiler is designed with longitudinal double drums and " D " type chamber structure. The combustion chamber adopts a membrane wall structure, which has good air tightness, no smoke leakage, and high thermal efficiency. Meanwhile, the tail of the boiler is equipped with flue gas condensation recovery devices to effectively control the exhaust temperature and increase the thermal efficiency to more than 98%. In addition, devices such as explosion-proof doors, flame detectors, water level alarms and water level interlocks are equipped to further ensure the safety of boiler operation.
A safe and high-efficient thermal oil heater is very important to an enterprise, which directly affects the product quality and the economic benefits. In November 2017, the burst of the pipeline of the existing thermal oil heater triggered a fire at Jiangxi Huachen Spice Chemical Co., Ltd. The fire caused considerable losses to the enterprise. Immediately, the leadership of the enterprise decided to repurchase a set of high-quality thermal oil boiler. With good market reputation and strong company strength, ZOZEN got the trust of Huachen Spice. ZOZEN YQW series gas-fired thermal-oil heater has excellent safety performance. The functions of over-temperature alarm, low oil level alarm and over-pressure alarm can ensure the stable operation of the heater. In addition, because the inner coil of the radiant section of the heater absorbs much more heat than the middle and outer rings, ZOZEN designed a large flow rate inner coil to ensure the safe and reliable operation at high temperature.
ZOZEN SZL series gas-fired boilers with excellent quality and outstanding performance has become the heat source equipment of many enterprises of the paper industry. This series of boiler adopts D-type arrangement and water tube structure. The large-volume combustion chamber has good air proof and ensures complete combustion. Meanwhile, good quality alumina silicate fiber and fire clay insulation material are used to control the boiler body temperature below 45℃, and greatly heat loss is reduced. Energy-saving devices are equipped at the end of the boiler to increase the thermal efficiency to above 98%. In addition, SZL series gas-fired boilers are easy to operate. Advanced PLC intelligent control systems with various protection functions such as automatic water supply, program ignition, over-temperature control and over-pressure control can reduce costs for enterprises.
ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
SZL series steam boiler is a longitudinal double-drum chain grate water tube boiler designed by ZOZEN on the basis of advanced international technology and its own experience. 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. the combustion air system (base) adopts independent compartment and scientific sealing structure; reasonable air conditioning device improves combustion efficiency. The water membrane wall, the front and rear arches and the hearth constitute the boiler furnace, A bank of return convection tube bundles are arranged at the rear of the boiler body to sufficiently absorb the heat released by the combustion. The SZL series chain grate steam boiler system customized by ZOZEN has excellent performance and the thermal efficiency is more than 5% higher than the similar boiler system on the market.
