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
Biomass-fired boilers are jointly developed and manufactures by ZOZEN boiler and Shanghai Jiaotong University. According to the fuel characteristics and combustion rate of various biomass-fired boilers, furnace arches, furnace walls and furnace heating surfaces can be rationally arranged to ensure high combustion and evaporation. Junhun Property mainly manages property management, house leasing, landscape afforesting design and construction, etc. In order to improve the heating quality of the community, Junhun purchased a 10t DZL series biomass-fired steam boiler (DZL-1.25-T) at ZOZEN. The fuel of biomass-fired boiler has wide adaptability and long service life. It is also recognized as a high-efficiency, energy-saving and environmental boiler product. At the same time, the input cost of biomass energy is relatively low, so biomass-fired boilers are widely used in urban industrial parks to meet the heating needs of the park.
