The principle of the biomass-fired thermic fluid heaters, after the fuel is ignited by the burner, the formed torch fills the disk tube and transmits radiant heat through the wall of the coil, which is the first return journey. The high temperature flue gas generated by combustion converged at the rear door, and turned into the second return journey, namely the convective tube bundle area. After convection heat transfer, the flue gas temperature gradually decreased to the front door, and then turned into the third return journey tube bundle area, and then entered the chimney and discharged into the atmosphere through the energy saver. The structure of three-return circular tube is adopted, and the end of the coil tube is made of tapered coil tube, which effectively protects the furnace wall at the end of the boiler. The boiler is equipped with advanced combustion devices and the operation of the boiler is fully automated.

With the characteristics of low pressure and high temperature, various series of thermic fluid heaters produced by ZOZEN boiler have become the heat source power for many chemical enterprises. Biomass heat-conducting oil boiler is a key equipment often used in chemical industry, which provides sufficient heat source and power source for chemical enterprises' production processes such as distillation, evaporation, polymerization, condensation/demulsification, lipidization and drying. At the same time, steam boiler is also the main energy consumption equipment in the production process, the use of energy saving boiler has a significant impact on reducing enterprise costs.

ZOZEN YLW series biomass thermal oil boiler is a square coil horizontal chain grate assembly boiler. The boiler body and chain grate are separated from the factory. After the site is in place, the boiler can be put into operation only by connecting oil and electricity. This series of boilers adopt the advanced structure form, the heating surface is sufficient, including the furnace radiation heating surface, the convection tube heating surface, the waste heat boiler and the air preheater four parts, ensure the high heat efficiency of the boiler; At the same time, according to the characteristics of different types of coal and biomass fuels, ZOZEN boiler improves the combustion chamber design, which not only ensures the full combustion of fuel, improves the combustion efficiency, but also reduces the formation and emission of flue gas and dust, thus becoming the heat source guarantee of product production line.

With the increasing demand for biomass heat-conducting oil boilers, there are more and more types of boilers in the market, leading to different prices in the boiler market. Users do not know how to choose when choosing boiler products. In fact, there are many factors affecting the price of the boiler, which require users to determine the boiler evaporation capacity, model, brand, thermal efficiency and other factors according to their own needs in order to give a specific quotation.
