ZOZEN Gas Steam Boiler and Thermal Oil Heater Used in Pesticide Product Project

With the tailor-made heating system solution, ZOZEN Boiler has undertaken the first and second phase boiler projects of Yichang Base, Jiangsu Changqing Agrochemical Co., Ltd., a leading pesticide enterprise. At present, the first batch of the gas steam boiler and thermal oil heater is put into operation, the technical difficulty of using thermal mutation in production has also been completely overcome.

Long-term cooperation, ZOZEN Boiler provides boiler for the production base

The fifth production base built by Changqing Agrochemical Co., Ltd., has a capacity of 13,700 tons of pesticide and 8,500 tons of chemical products in the first phase, 16,500 tons of pesticide and 20,000 tons of chemical products in the second phase, and ZOZEN Boiler provides the heating devices for the production line.

In this cooperation, ZOZEN Boiler not only provided a set of gas steam boiler, but also added gas thermal oil heater. ZOZEN gas thermal oil heater can supply heat at low pressure and high temperature by using the characteristic of large heat capacity of medium, and meet the high-temperature heat demand of production line on the premise of safe operation. The waste heat recovery device can improve the heating efficiency to over 95%.

The construction of Yichang base is an important link for Changqing to enrich its product structure and expand its production capacity. From boiler room plan design, civil engineering to on-site installation guidance, ZOZEN Boiler sent professionals to participate in the whole process, and provided professional technical support at the project site to ensure the project quality and speed up the project progress.

ZOZEN Boiler customizes the boiler solution of thermal oil heater

However, during the base construction, the production process of the first phase was suddenly changed, the heat consumption temperature increased to 310-315℃, and the heat consumption increased from 1.7 million kcal to 3.5 million kcal/h, resulting in the load of the thermal oil heater that had been put into operation could not meet the demand of the production line. At the same time, the boiler room and the pipeline of the whole system are laid according to the original project design scheme. If normal thermal oil heater products are adopted, some pipeline calibers need to be replaced, and the reconstruction cost is high. In order to catch up the progress of the project, the user proposed to solve the problem with short construction period and few changes.

After on-the-spot investigation and technical exchange, ZOZEN engineers designed a custom-made thermal oil heater with large temperature difference and small flow according to the heat and temperature used in process adjustment. The heat transfer medium is high-temperature heat transfer oil with high procurement cost. Also, it only changes the boiler room pipeline to separate the combined oil supply system, and the other boiler can use low-cost low-temperature oil, which effectively reduces the investment cost of heat transfer oil.

With the increase of boiler capacity, the occupied area exceeds the established boiler room planning. ZOZEN engineers rationally designed the system layout, and reduced the occupied area by designing the horizontal oil storage tank to be vertical. In addition, the engineers also advise users to upgrade all pipeline and valve fastener flanges to concave-convex structure. The purpose is to ensure that the connecting parts do not leak and the boiler system is safer and more reliable.
