Welding is an important working procedure in boiler production, which is generally divided into automatic welding, semi-automatic welding and manual welding.
ZOZEN YQW series horizontal thermal oil heater adopts multi-loop coil structure with good safety performance and sufficient heating surface. Meanwhile, ZOZEN Boiler can also design the waste heat recovery system for users to ensure that boiler's thermal efficiency can reach 95% and above. What's more, automatic control system also ensures the safe and stable operation of thermal oil heater to realize the sustainable high-temperature and low-pressure heating supply. In addition, ZOZEN’s gas-fired thermal oil heater is equipped with advanced low-nitrogen burner to ensure that boiler's NOx emission is lower than 30mg/Nm3 to achieve the excellent performance in environmental protection.
Recently, ZOZEN delivered the thermal oil heaters for Hengfa Energy Saving Technology. As a leading industrial boiler manufacturer, the thermal oil heaters of ZOZEN have wide adaptability of fuels, are suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. The heaters are also equipped with the advanced burners to ensure the NOx emission is below 30mg/m3.
In the process of milk powder production, a large amount of steam is required in various process steps such as sterilization, concentration and drying. ZOZEN provided several sets of SZS series gas-fired steam boilers for this milk powder company. This series of gas-fired boilers adopts water-cooled full-membrane wall structure and conducts air-tightness test before heat preservation to ensure that the boiler has no cross-smoke phenomenon during micro-positive pressure combustion, which also hel...
