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.
Industrial boilers have experienced numerous technological innovations. ZOZEN has optimized the boiler manufacturing process to make the boiler manufacturing more precisely. The worker is assembling the reinforcement rib on the drum. Every component is precisely assembled. It is the craftsmanship spirit of ZOZEN that make the product a work of art.
With more than thirty years of development, ZOZEN has achieved great achievement in the overseas market. Seeing is believing. A guest from France conducted a field inspection in ZOZEN. ZOZEN provides one-to-one customized boiler service and solutions for industries such as energy and minerals, agriculture, forestry, food, and chemical in many countries.
A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
Vietnam has abundant coal resources, including anthracite, bituminous coal, lignite, and peat. Vietnam anthracite has the characteristics of high calorific value, low ash, low nitrogen, low phosphorus and low sulfur. ZOZEN SZL series coal-fired boiler has wide fuel adaptability and sufficient fuel combustion, and has established an excellent reputation in the Vietnamese market.
