The development of technology and the progress of skill require the diversification of the quality of the sodium sulfide. Enterprises must produce different types of sodium sulfide according to different users. Taihua Industry is high-tech chemical enterprise. Its main products are pure benzene, toluene, p-tert-butyl benzoic acid, industrial sodium sulfide, anhydrous crystalline sodium sulfide and nine-hydrate crystalline sodium sulfide. The production of sodium sulfide requires high temperature and stable steam. Therefore, Taihua Industry has conducted an inspection of the same industry manufacturers and combined with actual conditions of the unit to transform the caustic soda production system in the evaporation section. At first, Taihua purchased a 2.4 million thermal oil heater at ZOZEN(YY(Q)W-2800Q) to improve utilization rate of heat energy. Later, in order to increase the coal utilization rate, Taihua purchased a 2.4million kcal thermal oil heater(YLL-2800MA(w)) at ZOZEN
Huagang Biological Feed Company was established in 2015 and is mainly engaged in feed processing and sales. Due to production needs, Huagang Biofeed added a 4-ton biomass-fired boiler to the plant to provide stable heat energy for drying feed. DZL series biomass-fired boilers are designed by ZOZEN and Shanghai Jiaotong University based on various biomass fuel characteristics and burning rates, and designed through numerical simulation, rational arrangement of furnace arches, furnace walls, and furnace heat receiving surfaces. In the production of biological feed in China and Hong Kong, there will be a large amount of crop residues, and ZOZEN proposes to use these residues as fuel for biomass-fired boilers. Compared with conventional boilers, the DZL series biomass-fired boilers have a large space in the furnace. At the same time, a very reasonable secondary air is arranged to make fuel fully burned, effectively reducing NOX emissions. The speed control box is configured for it, and the
Hebei Ruixin Jinhua New Energy Technology Co., Ltd. invested RMB 320 million in 2015 to build a 100,000-ton/year crude benzene hydrotreating project in two phases; in 2016, it invested RMB 120 million in equipment and manufacturing in District A of Fengfeng Mining Area. "Triazole, piperidone production project." In the early stage of the project, the technical personnel of ZOZEN boiler went to the customer site for field visits to help the customer analyze the equipment occupation area and site space planning. What’s more, the need of steam in the process must be high-temperature and stable. In the end, ZOZEN boiler design a thermal oil heater with a rated thermal power of 20 million kcal to the project for the customer. The boiler adopts ejected forced circulation system, it has a complete control system and safety monitoring device that can accurately control the working temperature and safeguard safety operation.
Wuxi kanglong Rubber Products Co. Ltd produces rubber and latex products including gloves etc.. During rubber material manufacture, vulcanization needs heating under 190-220°C, and finally create rubber. if by using steam boiler, the corresponding steam pressure is at least 2.5MPa, this boiler will be much more expensive and the whole system will be more expensive and high request. So thermal oil heater has unique advantage in rubber plant. It can reach high temperature under normal pressure; boiler construction cost is lower than steam boiler. Also, oil transfer heat more stable, it guarantees product can reach accurate temperature, which make process more accurately running. This heater has compact body, it is transport as a whole body, easy to operate. After visiting and technical discussing, customer chose ZOZEN thermal oil heater.
