2 ton central heating boiler for school horizontal, ZOZEN thermal oil heaters can realize the low-pressure and high-temperature heating
2 ton central heating boiler for school horizontal, 2020 is the start year of the construction of ZOZEN Boiler’s lean factory. As one of the key tasks of this year, based on the successful application of MES (manufacturing enterprise production process execution management system) informatization, ZOZEN Boiler will adhere to the lean management concept to build the digital lean factory, and implement the standardization of operation and workflow in every process of production and operation.

ZOZEN molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃, 2 ton central heating boiler for school horizontal.
The furnace of ZOZEN SZL series coal fired boilers adopts a close-packed a close-packed arrangement of water wall tubes. The application of close-packed water wall in furnace design changes the traditional structural form of the original industrial boiler furnace water-wall, effectively preventing high-temperature flue gas from scouring and radiating the furnace. Furnace radiation area is large, maintenance workload is small, overall weight is light.
During the production process, the CNC cutting rate of ZOZEN has reached more than 80%, which provides a strong guarantee for the welding and assembly quality of the boiler. Compared with flame cutting, the underwater plasma cutting used by ZOZEN has no deformation and splashing, which further improves the assembly accuracy between the components of the boiler, thereby achieving accurate assembly of the entire boiler.
The complete set of WNS series gas-fired hot water boiler system customized by ZOZEN Boiler for Jilin Mingde Education adopts the corrugated furnace which not only increases the strength and flexibility of the furnace, but also enhances the flue gas disturbance to effectively improve the heat transfer effect. The threaded smoke tube with advanced manufacturing technology has been continuously optimized to effectively absorb the flame energy, and its heat transfer coefficient is 1.2 times higher than that of ordinary smoke tube. At the same time, with the additional finned tube condenser at the end of the flue gas duct, the exhaust gas temperature can be lowered and the boiler thermal efficiency can be as high as over 95%. According to the energy efficiency test conducted by the Thermal Energy Testing Center of the Special Inspection Institute, the performance indicators of the WNS series gas-fired boiler are higher than design requirements and have reached the advanced level at home and abroad.
2 ton central heating boiler for school horizontal, Industrial boiler belongs to special equipment and has high requirements for product safety factors. As the domestic well-known boiler supplier, ZOZEN has advanced mechanical equipment, mature manufacturing process and guarantee of boiler quality. In addition, via the innovation and development of ZOZEN’s professional design team, the structure and material of boiler proper are continuously improved and optimized to greatly extend boiler’s service life. It is also worth mentioning that ZOZEN’s automatic boiler control system with dozen kinds of safety protection interlocks can fully ensure boiler’s safety. In the aspect of environmental protection performance, ZOZEN boilers are also outstanding. The flue gas emission of ZOZEN boilers nearly meets the EU standards. The NOx emission is low to 30mg, which realizes the goal of low-nitrogen emission.
