difrence wet back boiler and dry back boiler, vigorously developping the industrialization of natural gas, ZOZEN gas-fired boilers contribute to the environmental protection

It is known that the whole sales network of ZOZEN Boiler includes three main lines. The southern line goes through India, Laos, Vietnam, Thailand, Philippines, Malaysia, Indonesia and other countries, across the Asia and to Oceania, and settles in Australia, Papua New Guinea, New Zealand and other countries. The northern line reaches to Mongolia, Russia, Kazakhstan and other eastern European regions. The western line passes Pakistan, Oman, Ethiopia to South Africa, the rainbow country at the southernmost point of African continent. ZOZEN also builds local service centers in Thailand, Indonesia, Philippines and other countries to quickly respond to the demands of customers, difrence wet back boiler and dry back boiler.

difrence wet back boiler and dry back boiler, During the "Thirteenth Five-Year Plan" period, China's oil refining industry will focus on transformation and upgrading, and continue to enhance comprehensive strength. It will vigorously eliminate backward production capacity and improve the scale and technology of its units. Among them, the boiler as an important piece of energy equipment is indispensable in the petroleum refining process.

The SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.

ZOZEN’s YLW series coal-fired/biomass-fired thermal oil heater has wide fuel adaptability to various kinds of coal and biomass. The boiler’s heat exchange surface adopts square coil structure with more sufficient heating surface and higher thermal efficiency. With the flue gas waste heat system, the thermal efficiency can reach to 85%. Meanwhile, advanced measurement and control systems of oil temperature, smoke temperature and oil pressure can ensure the long-time and stable operation of the thermal oil heater. ZOZEN has successfully provided the stable heat source for the forming and drying processes in the production of laundry soap, bath soap and other products of Azhar Corporation (Pvt) Ltd..

The grate bracket adopts double brackets, the lower channel steel, the upper light rail, the upper heat, the lower force, which has changed the structure of the traditional grate bracket angle steel plus friction bar, the grate bracket is not deformed. The active stoker is operated on the light rail and it is tested in the cold state for 48 hours before leaving the factory. Never run sideways, stuck, which ensure the smooth operation of the stoker, difrence wet back boiler and dry back boiler.

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.

difrence wet back boiler and dry back boiler, ZOZEN will always adhere to technology research and development, and continue to provide efficient and energy-saving boiler systems for enterprises, further contributing to the high-quality development of the domestic fine chemical industry.
