heavy oil fired fire tube hot water boiler, ZOZEN Boiler with experts from the consulting project team organized a series of internal training courses

ZOZEN DHL series coal-fired water tube hot water boiler is popularized and applied in Liaoning Province, and is also an ideal heating equipment for central heating.

The DHL series coal-fired corner tube boiler is field assembled boiler. It uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increasing.

ZOZEN boilers adopt the ultra-low nitrogen burner with flue gas recirculation method to realize low NOx emission. Adding flue gas to the combustion air to reduce the oxygen content in the combustion air and lower the flame temperature at the combustion center, so as to greatly reduce the generation of NOx. At the same time, superimposed use of world advanced technologies such as staged combustion of ultra-low nitrogen burner and internal flue gas circulation realizes the stable and low emission of NOx.

ZOZEN Boiler has set up seven process stop points that are material re-inspection, material inspection number transfer, plate welding test, heat treatment, pre-expansion before welding, flaw detection inspection, hydrostatic test, which are inspected by seven responsible engineers. If any link is unqualified, it will not be able to proceed to the next process, which ensures that each ZOZEN boiler has the high quality, heavy oil fired fire tube hot water boiler.

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.

The two sides cooperated well for the steam boiler project in Bangladesh. ZOZEN will continue to provide high quality products for the global industrial boiler market in the future, heavy oil fired fire tube hot water boiler.
