ZOZEN energy-saving oil-fired boiler can be divided into steam boiler, hot water boiler and thermal oil heater. Heating temperature up to 320℃ under normal pressure is one of the unique advantages of energy-saving oil-fired boiler with heat conduction oil. ZOZEN energy-saving oil-fired thermal oil heater adopts three-loop coil tube design, and the end of the coil tube adopts necking coil tube, with reasonable distribution of convection section, high safety factor and thermal efficiency of over 95%.
Thermal oil heaters are widely used in chemical industry, printing and dyeing, edible oil processing and other industries because of their low pressure, high temperature and precise temperature control. ZOZEN gas-fired thermal oil heater adopts multi-loop round coil structure, with large heat exchange area, high thermal efficiency and fully automatic and safe operation.
YLM thermal oil heater is square coil horizontal chain stoker assembly heater, chain stoker and heater body are transferred separately. It adopts chain stoker to realize mechanical feeding coal, mechanical venting by blower and exhaust fan, and mechanical discharging by slag machine.
YLW series thermal oil heater is square coil horizontal chain grate shop-assembled heater, chain grate and heater proper are transferred separately. The pictures show the chain grate which is autonomously designed and produced by ZOZEN with reliable quality.
ZOZEN YLW series coal-fired and biomass-fired chain grate thermal oil heater is favored by Indonesian customers because it has the features of high temperature and low pressure, precise temperature control and high quality. Heater proper and chain grate are transferred separately. The pictures show the heater proper is on the delivery. YLW series thermal oil heater adopts the square coil structure to realize high safety and sufficient heating surface. The tubes are firstly bent by CNC 3D tube bending machine, then welded to link together without forced assembly. YLW series thermal oil heater adopts the structure of a large furnace to achieve sufficient combustion and realize the thermal efficiency of over 85%. It is available for the bituminous coal, anthracite, all kinds of biomass particles, sawdust, etc.
The Dongwha Finland plant is located in southern Finland. The plant has been owned by Dongwha Enterprises since 2017, mainly produces wide range of different types of impregnated papers. ZOZEN Boiler provided a set of 7 million kcal thermal oil heater to Dongwha Finland under the strict circumstance of COVID-19 pandemic.
Continuing the 2020 industrial live streaming mode, ZOZEN Boiler has made the online visit normal. Recently, at the modern production base of Wuxi ZOZEN Boiler, technicians had connected with Finnish customers via the live streaming to show the whole process of the boiler hydrostatic test. Through the live streaming, ZOZEN not only showed the entire panorama of the hydrostatic test, but also showed the operating steps and pressure gauge values on the top of the boiler. The customers were very satisfied.
The YQW series gas/oil-fired thermal oil heater adopts the three-pass round coil whose end adopts the necking coil, which effectively protects the furnace wall at the boiler end. It is equipped with the advanced combustion device and fully automatic operating device. The boiler adopts the packaged structure for delivery, and it can be put into operation only by connecting gas (oil) and electricity after being placed on the project site. With excellent performance and quality, ZOZEN YQW series gas-fired thermal oil heater has won the favor of Jiangsu Guanghui Packaging Materials Co., Ltd.
