Tannery transforms raw hides and skins into leather for manufacturing articles like shoes, bags, suitcases, belt, wallet, jacket and many other products. The production of leather requires a lot of steam, and the quality of the steam can change the breathability and corrosion resistance of the leather. At the earliest time, the treatment of leather made the physical methods such as depilation and tanning very poor in gas permeability and corrosion resistance. After chemical treatment with some plant juices and mineral oils, the antiseptic and breathability began to improve, and now it is used in technology. The high-temperature steam treats the leather, and the treated leather imparts physical properties such as softness, tear resistance, and tortuosity. In tanneries, steam is required for heating, drying, and equipment heating. It is very important to choose the right 25 ppm of hydrazine in 25 tons boiler.

Buy a 10-ton fuel 25 ppm of hydrazine in 25 tons boilers How much? Jilin a factory Consulting fuel gas-fired boiler manufacturers invest a 10-ton fuel funds required boiler includes upfront fees and late fees, early 10 tons of fuel body cost boiler, transportation costs, installation costs, late fees mainly operating costs, labor costs and maintenance costs. Its price is mainly composed of two parts, fuel boiler and auxiliary equipment. 1, and the price of the boiler steam boiler pressure, steam temperature and other parameters related to the boiler steam pressure of 10 tons of fuel oil are 1.0MPa, there 2.5MPa, the greater the pressure, the higher the temperature, the higher the requirements of the boiler wall thickness of the body, producing the higher the cost, the price will be high leading to the boiler. After determining general parameters, boiler fuel prices also determined. 2, not only to consider the number of auxiliary auxiliary, but also consider the brand and auxiliary materials used. For example, the optional burner different, big price disparity. Since the fuel oil-fired boilers there are some differences with a heavy oil, residual oil, light diesel oil, etc., used in different fuel burner, naturally the price difference; the higher the required boiler combustion efficiency, the lower the NOx emissions the corresponding burner performance, the higher, the more expensive price. 3, different type of boiler, boiler prices there are differences, such as the high price SZS oil-fired boiler oil-fired boiler WNS than the price can not be determined by the price boiler models, both boilers have their own characteristics, to select the best fit . To sum up, wondering to buy a 10-ton oil-fired boiler how much money you need to tell Henan fast boiler fuel you use, the steam pressure, steam temperature and other parameters, we can make a quote ready for you, we can offer you a quote It is free, and your purpose is to facilitate the comparison of reference.
