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
Henan Shunxiang Differential Fibre Products Co., Ltd. mainly uses recycled polyester bottle tablets as raw materials to process and produce artificial down, tow, three-dimensional hollow and differentiated functional fibers, with an annual output of 30,000 tons of differentiated fiber products. It is the largest domestic production capacity of ultra-fine hollow imitation down production enterprises. In recent years, with the rapid development of the chemical fiber industry, there are more and more polyester devices in various regions, and the heating devices in polyester devices have also become diversified. In addition, as the country promotes the replacement of gas for small boilers, the new chemical fiber and textile mills are now forced to abandon coal-fired boilers and turn to gas-fired boilers. However, the consumption of gas-fired boilers is higher than that of thermal oil heater. In consideration of several aspects, Shunxiang purchased a horizontal gas-fired thermal oil hea
