bs stanadard for boiler steam purity, ZOZEN boiler provides high quality and high standard experience for building materials industry

bs stanadard for boiler steam purity, ZOZEN is not just a company that only responsible for manufacturing boilers. Instead, ZOZEN takes responsibility in every step and offers the most effective and fastest service to resolve any problems for customers, including pre-consultation and after-sales services. 

Samsung Electronics is the largest electronics company in Korea. As early as 2012, Samsung Electronics has invested 7 billion US dollars to build a semiconductor production base in Xi'an. Boiler is an important piece of equipment to ensure the constant temperature, constant humidity and ultra-clean environment of the semiconductor production workshop.ZOZEN finally won the trust of each other with excellent comprehensive strength, and started the first cooperation between the two parties since then.

bs stanadard for boiler steam purity, The WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.

This time, GOTEC Group built a new plant in Toluca, Mexico, to expand its world map. As the important energy equipment for a new plant, the efficient and stable operation of the gas-fired hot water boilers would directly affect the company’s production efficiency and product quality. Based on previous friendly cooperation with ZOZEN, GOTEC Group appreciated ZOZEN’s WNS series gas-fired hot water boiler. Aiming at the characteristics of load changes in the actual production process of the Mexican plant, ZOZEN equipped the easy-to-operate PLC automatic control system for the boilers. The PLC automatic control system adopts advanced frequency conversion technology and fuzzy control technology to achieve high-efficiency and energy-saving operation by changing the gas volume of the boiler. After the automatic function is turned on, the controller can also automatically control the system according to the mode set by the user to ensure the safe and stable operation of the boiler, bs stanadard for boiler steam purity.

Increase stoker availability of stoker, guarantee boiler safely running. ZOZEN biomass-fired fuel has another character, which is high volatility and low ash content. After combustion, there is almost no ash left on the stoker, so stoker should adopt proper high temperature resistance material to work under high temperature radiation.

The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler, bs stanadard for boiler steam purity.

Moreover, ZOZEN professionals provide full guidance from the installation and the trial operation of the boiler to the training of the boiler operator, so that each user can enjoy one-stop worry-free service from pre-sales to after-sales.
