【Major Chemical Equipment】066 – The Largest Single Unit Heating Furnace Exported Abroad
Thread Content
The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! *********************************** In December 2016, the 15 million tons per year atmospheric pressure furnace for Malaysia’s RAPID project was manufactured in the Lingang Equipment Industrial Park of Xiangshan Economic Development Zone, and was then officially shipped for delivery (as shown in the figure). This giant structure, measuring 25 meters in length, 17 meters in width, and 26 meters in height, with a weight of 978 tons, is the first set of equipment in China to be manufactured using modular construction methods for entire furnaces. It is also the largest heating furnace of its kind to be exported abroad, marking the localization of modular manufacturing technology for large-scale heating furnaces and its successful application in overseas projects.

At that time, the design was based on foreign concepts, led by Hestie from France.
Now many companies can do this
Companies that started implementing this concept were good; now, basically everyone accepts it, and they are even doing better and growing larger
Ningbo Tongliang is in charge of the manufacturing work for the atmospheric pressure furnace, residue oil furnace, and hydrogen production converter in Malaysia’s RAPID project. The modular manufacturing technology for the atmospheric pressure furnace has reached international advanced levels; the key objectives of this effort are the modular manufacturing process for the entire furnace, the assembly of the furnace components at the dock, and the transportation of the complete furnace. The atmospheric furnace manufactured in a modular manner as a whole consists of two radiation chambers, transition corner flues, a convection section, and a reinforcing frame. Its overall dimensions are 25 meters in length, 17 meters in width, and 26 meters in height, with a total weight of 978 tons. Modular manufacturing of entire furnaces requires extremely high quality and precision to ensure successful on-site assembly in one attempt. How to address the deformation of steel structures, wall panels, and linings during transportation and lifting is a major challenge that must be overcome in the design and manufacturing process. In July 2015, Heurtey Petrochem officially commenced the design process, and Ningbo Lian Tong Equipment Group Co., Ltd. got involved thereafter. By using techniques such as 3D modeling, and through repeated communication with the manufacturing team, installation team, as well as the transportation and lifting teams, they continuously optimized the design plans and manufacturing processes. Ultimately, a practical modular solution for the entire furnace is developed. In June this year, after the design was completed, Ningbo Lian Tong immediately assembled a core team to form a project team, leveraging the company’s various resources to carry out meticulous manufacturing. On December 5, the production of the first two atmospheric pressure furnace modules was completed; they were sent to Xize Wharf for installation and successfully loaded onto the ship. The entire furnace module is expected to arrive at the site in Malaysia in late December, and the installation of the two atmospheric pressure furnaces can be completed within 1 week. Compared to traditional manufacturing methods, these two heating furnaces save at least half a year of time.
The 15 million tons per year atmospheric furnace, manufactured using a modular design for the entire furnace, under Malaysia’s RAPID project, was successfully assembled at Sa Ze Wharf in Xiangshan. This marks the localization of the modular manufacturing technology for large-scale heating furnaces, as well as its successful application in overseas projects. This project represents the first set of modularly manufactured furnaces in China, and it is also the largest single heating furnace unit to be exported abroad. The modular design and manufacturing of entire heating furnaces represent a development trend in the international petrochemical equipment industry; however, there are no precedents for this in China, and this constitutes a bottleneck that prevents domestic petrochemical equipment manufacturers from entering international markets. This technology of modularly disassembling and producing the heating furnace, transporting it to the site for assembly, represents a completely new concept introduced in the domestic manufacturing of heating furnaces. Compared with traditional on-site manufacturing techniques, it offers advantages such as precise control, high efficiency, good quality, and a short construction period. It also eliminates the need for simultaneous operations during on-site construction, thereby significantly enhancing the safety level of the work. Following thorough consultations and discussions among the general contractor, the designer, and the manufacturer, Sinopec Engineering Construction Co., Ltd. decided to adopt modular manufacturing for the atmospheric furnace and residue oil furnace in the RAPID project in Malaysia. The design was carried out by Heurtey Petrochem, while the manufacturing was undertaken by Ningbo Liantong Equipment Group Co., Ltd.
