sv pump 20 compressed air oil pump for boiler, ZOZEN adopts the low NOx burner to reduce the NOx emission of boilers

In recent years, with the deepening cooperation between China and Africa, ZOZEN and KPC have built a friendly cooperation relationship with the oil-fired steam boiler project. In the petroleum processing industry, steam is the main factor affecting the energy consumption of enterprises. The safe, efficient and energy-saving boiler system directly determines the quality of oil products and the economic benefits of enterprises, sv pump 20 compressed air oil pump for boiler.

During the processing of broilers, whether it is retort sterilization, baking and cooking, or heating and drying, the heat source provided by the steam boiler is required. ZOZEN successfully won the full recognition of the Chia Tai Group with its systematic solutions, and became the  General Contractor of Jilin Zhengda Boiler, providing it with three 1.2 million kcal gas-fired thermal oil heaters, including pipe laying from the boiler room to the production floor.

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.

In the Harbin area, Heilongjiang Branch of Industrial and Commercial Bank of China, Harbin Investment Group, Harbin Coslight Battery, Veolia (Harbin) Thermal Power and other companies all use eco-friendly gas-fired boilers produced by ZOZEN. It is understood that in the industrial gas-fired boiler market, the coverage rate of ZOZEN gas-fired boiler is as high as 90%. This is not only due to the strength of ZOZEN with a wide range of boiler types and a capacity ranging from 1 to 110 tph, which can meet the demands of enterprise production and heating, but also due to the advantages of the boiler itself.

sv pump 20 compressed air oil pump for boiler, The furnace of ZOZEN SZL series coal fired boilers adopts a close-packed a close-packed arrangement of water wall tubes. The application of close-packed water wall in furnace design changes the traditional structural form of the original industrial boiler furnace water-wall, effectively preventing high-temperature flue gas from scouring and radiating the furnace. Furnace radiation area is large, maintenance workload is small, overall weight is light.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality.

ZOZEN Boiler has always invested a lot in the research and development of the environmentally friendly industrial boilers with the long-term strategy and firm determination to bravely move forward on the road of green and sustainable development.
