Thermal oil heater is used to provide heat energy for the reaction and fractionation process of residual oil hydrogenation in chemical industry. Shandong Guangyue Chemical Co., Ltd. is a new comprehensive chemical enterprise, which is engaged in petroleum processing, warehousing logistics and international trade services. The construction of its second project starts in 2018, planning to build 1.6 million tons residual oil hydrogenation each year. ZOZEN has rich experience in chemical industry. ZOZEN’s manufacturing technology of thermal oil heater is unique and inimitable, ensuring the high quality of boilers. After professional explanation by ZOZEN’s engineer, this project leader ordered one set of 21 MW YQL series gas-fired thermal oil heater. This thermal oil heater adopts multi-return coil tube design, which features safer operation, sufficient heating surface and 95% thermal efficiency. It is also equipped with low nitrogen burner for energy saving and environmental prote
In the production process, the feedstuff needs to be heated and matured to facilitate digestion and absorption by the animal. Therefore, the heating boiler is an indispensable equipment for feed production. As a national large-scale farming and animal husbandry group, the Twin Group has been dedicated to feed R&D and manufacturing, pig production and grain trading since it was founded in 1998. In the early stage, when the Yulin Twins subsidiary purchased the boiler, it was aware that the water in the heating boilers on the market was not uniformly heated, the heating was slow, the water vapor was insufficient, and the efficiency was low, affecting the feed production. After a long time visit to the major boiler plants, the principle of Yulin twin company found that, whether the welding process, production equipment, or the rational scientific design of the boiler, technology research and development team, ZOZEN boiler is the best in the country. Yulin Twins finally ordered a 12-ton SZL
