A steam boiler is a piece of vital equipment in the production processes of food industry such as stewing, drying, concentrating and sterilizing. Jiaozuo Yuzhu Instant Noodle Company, affiliated with Henan Province state-run Boai Farm, is a national professional manufacturer of instant noodles with the annual production capacity of over one hundred thousand tons; the instant noodles produced by the company are sold very well all over the country. China is advocating the development of green economy in recent years; Henan Province is vigorously controlling pollution and reforming coal-fired boilers to gas-fired boilers. As the only state-owned enterprise of instant noodle industry, Jiaozuo Yuzhu Instant Noodle Company actively promoted the "coal to gas" action and ordered one set of 25 tph gas fired boiler (SZS25-1.25-Q) from ZOZEN. The boiler is equipped with a large volume furnace and an advanced imported low NOx burner to effectively reduce the NOx emission. In addition, the boiler
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
