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%
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 YQW series thermal fluid heater is simpler to operate. The thermal fluid heater is completely assembled before shipment, which is easy to install, debug and use. This series of gas-fired thermal fluid heater has the features of automatic operation and adjustment of combustion, high tank level, outlet temperature and flow rate. The inlet and outlet of this product adopt the flanges and flange cover structure at both ends to facilitate the installation and arrangement of the boiler room pipes.
The company is an auto parts company mainly engaged in the production of automotive plastic inner and outer trim parts, epp foam parts and engine plastic parts. ZOZEN provided WNS series gas-fired steam boiler for the company. This series of condensing gas-fired boilers is horizontally arranged, compact in structure and small in floor space. The combustion chamber adopts a large-diameter corrugated furnace to reduce the thermal stress and enhance the smoke disturbance, therefore, improving the h...
Relying on the industry-university-research cooperation and large-scale production, ZOZEN has manufactured more than 400 varieties of specifications of industrial boilers including gas-fired boilers, coal-fired boilers, biomass-fired boilers and thermal oil heaters.Develop up to now, the annual production scale of ZOZEN has exceeded 2,000 sets and 25,000 tph.
