heating coal fired boiler, ZOZEN thermal oil heaters adopt the special technology to reduce the dewatering time

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. 

heating coal fired boiler, The ZOZEN WNS series oil-fired steam boiler was successfully delivered to the capital of Caracas, Venezuela in early June. After completing the installation and commissioning the boiler will provide a stable heat source for the production line of Inversiones Goa 7 C.A, further enhancing the efficiency and overall competitiveness of the enterprise.

ZOZEN’s YQ(Y)W series oil-fired/gas-fired vertical thermal oil heater adopts three-pass round coil structure whose end adopts conical coil which can effectively protect the furnace wall at the end of boiler. It is equipped with advanced combustion device with good energy saving and environmental protection performance. This kind of boiler has the characteristics of wide fuel adaptability, low pressure and high temperature, safety and efficiency, high thermal efficiency over 95%, and complete automatic control system which can realize unattended operation, heating coal fired boiler.

ZOZEN WNS series gas fired boiler not only adopts advanced low NOx burners. And through the flue gas recirculation technology, about 10% -30% of the flue gas at the tail of the boiler is sucked into the air inlet of the burner through the flue gas pipe, mixed with the combustion-supporting air, and then entering the furnace, thereby reducing the temperature and oxygen concentration in the combustion area, and finally reducing The amount of thermal NOx is generated, and the NOx in the tail gas of the boiler are less than 30mg/Nm3, which meets the requirements of low nitrogen emissions of the enterprise.enterprise.

The longitudinal and circumferential seam welding of ZOZEN adopts advanced submerged arc automatic welding technology to ensure the welding quality. All longitudinal and circumferential seams are subjected to 100% radiographic inspection.

As one of the project cores, the gas-fired boiler with a rated pressure of 3.82 MPa and a rated steam temperature of 450°C is a mid-temperature and mid-pressure boiler, which puts forward high requirements for the manufacturer’s comprehensive strength. Facing similar competitors, ZOZEN Boiler with rich project experience and excellent product performance provided a satisfactory gas-fired boiler solution for Changfeng Coking and successfully obtained the supplier qualification.

heating coal fired boiler, In recent days, ZOZEN YLW thermal oil heater was successfully shipped. It could be put into operation immediately by simply switching on the power. The easy installation will help Kay & Emms save a lot of installation cost.
