YQW series thermal oil heater adopts three-pass round coil structure with larger inner coil design to ensure boiler's safe operation under high temperature. It is also equipped with advanced burner and control system. They realize the automatic and stable operation of thermal oil heater. There is waste heat recovery device as well to improve the thermal efficiency to 95% and above.
This video is a case collection of ZOZEN's WNS series steam boiler with 10 tph capacity. ZOZEN’s WNS series steam boiler is a kind of horizontal internal combustion wetback boiler and is popular among enterprises in various industries since being launched. This type of boiler adopts wetback structure and is equipped with advanced low NOx burner, which can effectively improve the combustion efficiency and reduce the NOx emission to realize the purpose of energy conservation and environmental protection.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
The YQW series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PLC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface.
This SZL series boiler is designed and developed by ZOZEN, which has the characteristics of wide adaptability of coal type, compact design and convenient installation. Benefiting from its outstanding performance advantages, this series of chain furnaces successfully won the favor of Agra Feed S.A.S. In order to improve the actual efficiency of the company, ZOZEN also customized a complete set of steam boiler system with a thermal efficiency of over 82%. Meanwhile, according to the environmental protection requirements of the region, ZOZEN also installed dust removal, desulfurization and denitration facilities to effectively reduce NOx emissions.
Founded in 2002, Wujiang XinYi Textile Co., Ltd. is a joint-stock private enterprise integrating production and trade of various kinds of high-end fabrics. With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control.
The chain grate boiler is a grated fired boiler with a high degree of mechanization, the chain grate is the combustion equipment. The working principle is to drive the chain grate to rotate by the reducer, so that the solid fuel can be fired from the front to the end of the boiler, and the combustion efficiency is greatly improved compared with the fixed grate. When the chain is turned to the bottom, the air cooling lower the temperature, which can protect the grates from burning loss.
This series of double-drum steam boilers adopts a full membrane wall structure with good sealing performance. It is designed with large furnace to ensure full combustion of fuel and the thermal efficiency is over 98%. Meanwhile, this series of gas-fired steam boilers has reliable water circulation. Besides, the arrangement of various safety devices such as explosion-proof doors and flame detectors make the boiler operation safer and more reliable.
