To meet Ningde Amperex Technology’s demands of production line reconstruction, ZOZEN Boiler designed the YQW series gas-fired thermal oil heater that could realize low-pressure and high-temperature heat supply and precisely control the temperature of heat medium oil to further guarantee the steady heat supply for the battery production line.
The new process using the ethylene oxide method has low production costs and stable product quality, however, the yield of the ammonification process and the production continuity are the key points in the process. Therefore, Jiangyin Huachang Food Additive Co., Ltd. has set clearly high requirements for the entire boiler system. ZOZEN Boiler tailor-made the design of the YQW+WNS series boiler system project in order to meet the sufficient and continuous heating source support of the food additive production line. Among them, the body of YQW series gas-fired thermal oil heater adopts three-pass round coiled tube structure, with sufficient heating surface, and the energy-saving device installed at the end of the furnace can ensure the thermal efficiency up to 95%. The advanced combustion device can realize low NOx emissions of the entire boiler system, meanwhile ZOZEN Boiler has equipped the automatic control system to ensure the continuous and efficient operation of the heating source
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
Jiangsu Hengtong Printing and Dyeing Group Co., Ltd. set high requirement for the automatic operation and safety of the thermal oil heater which had great importance to its production line. After rigorous market research, Hengtong purchased a set of ZOZEN YQW series gas-fired thermal oil boiler in 2018. Equipped with an advanced burner, this 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. In addition, the boiler has been in stable and high-efficient running since its operation, which was highly praised by Hengtong. This time, with the expansion of the production scale, Hengtong planned to get another thermal oil heater and cooperate with ZOZEN again.
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.
With features of low pressure and high temperature, ZOZEN various series of thermal oil heaters have become heat source of many chemical enterprises. ZOZEN YLW series coal-fired(biomass-fired) thermal oil heater is a square coil horizontal chain grate shop-assembled heater of which the chain grate and heater proper are transported separately. Once connected the oil and electricity, the heater can be put in use. This series of heater adopts an advanced structure, including four parts: the radiation furnace heating area, convection tube bundle heating area, waste heat boiler and air heater, which has sufficient heating area and ensures high thermal efficiency of the boiler. Meanwhile, ZOZEN reasonably designed the combustion chamber according to different characteristics of different types of coal and biomass fuel, which not only ensures the complete combustion of the fuel but also improves the combustion efficiency and reduces the formation and emission of flue gas. This series of heate
Because of the characteristics of high temperature and low pressure, the thermal oil heater becomes an important piece of equipment of the fine chemical industry. Wuhai Shilian Environmental Protection Technology Co., Ltd. was established in April 2018. With a total investment of 320 million yuan, the company was a reorganization of Wuhai Black Cat Sanxing Fine Chemical Co., Ltd. After sufficient market research and technical demonstration, Wuhai Shilian decided to re-plan the product structure of the original company and invest a 20,000-ton-per-year phenol series technology transformation project including 10,000 tons annual output of resorcinol, which is mainly used for rubber adhesives.
This series of thermal oil heater can realize low-pressure and high-temperature heating by utilizing the characteristics of the thermal oil heater. The high thermal inertia can effectively maintain the temperature uniformity during the food heating process. This thermal oil heater has outstanding energy-saving effects and low operation costs. It adopts closed-loop circulating liquid phase to transfer heat energy, the heat loss of steam boilers such as heat running, dripping and leaking can be avoided. Meanwhile, a complete operation control system and safety monitoring devices are equipped to precisely control the working temperature. It was the mix of these advantages that effectively reduced the production costs and improved the production safety of Changling Food.
