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
Pharmaceutical production companies are inseparable from steam boilers, and Jiahe Pharmaceuticals is a modern pharmaceutical company integrating pharmaceutical production, sales, and research and development. In recent years, R&D investment in technology innovation has been continuously increased. In terms of boiler room renovation, Jiahe Pharmaceutical has learned that ZOZEN boiler is the first business in China to use an arched tube plate and a threaded tobacco pipe structure to increase honduction and completely solve the problem of cracking of the rear tube plate. From the aspect of making boilers, Jiahe Pharmaceuticals has decisively selected the "Zozen Brand" 4-ton biomass-fired steam boiler (DZL4-1.25-T). The boiler is a horizontal three-pass water-fire pipe chain grate boiler with compact structure and simple size. After the completion of the transformation, it is expected that Jiahe pharmaceutical company will achieve leapfrog development in the next few years.ZOZEN
