This kind of heater adopts three pass circular tube design for sufficient heating surface, and the waste heat boiler and energy-saving device disposed at the tail of the heater can greatly reduce the loss of thermal energy, the thermal efficiency can be as high as 95% or more. Advanced low NOx burner can achieve NOx emissions below 30mg/Nm³. And the operation of the thermal oil heater can realize full automatic control, and can automatically adjust the combustion, high tank level, outlet temperature and flow to ensure the safe operation. This series of thermal oil heaters are favored by all walks of life in the chemical, rubber and food industries.
Veolia (Harbin) Thermal Power Co., Ltd. was established in 2003 and is a Sino-foreign joint venture controlled by Veolia Group. ZOZEN customized a complete boiler system including multiple sets of WNS series gas-fired hot water boilers. This series of gas-fired boilers adopts full corrugated furnace to increases the strength and elasticity of the furnace and enhances the disturbance of the flue gas, effectively improving the heat transfer effect. The threaded fire tubes can effectively absorb the flame energy, and the heat transfer coefficient is 1.2 times higher than that of the ordinary tube. At the same time, the finned tube condenser added at the end of the flue can increase the boiler thermal efficiency to over 98%
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
In the petroleum industry, steam is the main factor affecting the energy consumption of enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. ZOZEN provided the company with SHL series field assembled water tube steam boiler. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler.
ZOZEN YY(Q)L series vertical thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN YY(Q)W series horizontal thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN WNS series gas-fired (oil-fired) boilers adopt large diameter corrugated furnace for sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
The ZOZEN coal-fired hot water boiler helped the heating company to successfully complete the centralized heating task in winter with its excellent performance, reliable operation and friendly environment performance. The tailor-made boiler system of ZOZEN realized the high efficiency and energy saving of the heating system, and provideD sufficient heat source protection to ensure the warmth of the people in the area.
