price of boiler 3 tons, ZOZEN gas-fired boilers use the economizer and condenser to realize the energy-saving effects
As a kind of special equipment widely used in the industrial production, boilers require more strict requirements for manufacturers for the improvement of boiler performance and parameters. Wuxi ZOZEN Boilers Co., Ltd. is a professional A-grade boiler manufacturer engaged in the boiler industry for more than 30 years. The company has strong comprehensive strength, a wide range of products (boiler working pressure can be up to 5.4 Mpa), and abundant project experience.


ZOZEN SZL series chain grate boilers have high combustion efficiency, strong overload capacity, wide coal type adaptability. The boiler is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers and headers. The upper and lower drums are longitudinal arranged. The combustion equipment adopts the chain grate with chain belt and is driven by a stepless speed change device.
ZOZEN’s SZL series chain grate boiler has an independent water circulation system to ensure the safety and reliability of boiler’s water circulation. ZOZEN also designs independent water circulation systems in structure. The water circulation structure is simple and the division of water supply work is clear, which ensures that the cross-sectional area ratio of downcomer to riser is larger than 0.4 in order to ensure the safety of boiler’s water circulation under the premise that the water quality meets the GB standards, price of boiler 3 tons.
The boiler hydrostatic test is a test of strength and tightness with pressurized water after the boiler or components are assembled. The main purpose of the hydrostatic test is to test the tightness and compression strength of boiler pressure-bearing components, tell whether there is leakage of welding seams, flange joints and pipe expansions, and watch the deformation conditions of pressure-bearing components with naked eyes. Practice has proved that the boiler defects can be found through the hydrostatic test, and the safety of boiler operation can be ensured after the corresponding measures are taken in time. Therefore, the hydrostatic test is an important step and means to ensure the safe boiler operation.
ZOZEN’s YLW series coal-fired/biomass-fired thermal oil heater has wide fuel adaptability to various kinds of coal and biomass. The boiler’s heat exchange surface adopts square coil structure with more sufficient heating surface and higher thermal efficiency. With the flue gas waste heat system, the thermal efficiency can reach to 85%. Meanwhile, advanced measurement and control systems of oil temperature, smoke temperature and oil pressure can ensure the long-time and stable operation of the thermal oil heater. ZOZEN has successfully provided the stable heat source for the forming and drying processes in the production of laundry soap, bath soap and other products of Azhar Corporation (Pvt) Ltd..
In recent years, attention to environmental protection and sustainable development has been raised to a new height. Both Lenzing Group and ZOEN Boiler are constantly practicing the concept of sustainable development. There may still be new challenges in the future, but as a large-scale enterprise with social responsibility, ZOZEN Boiler will continue to insist on technological innovation and work with partners to achieve the unified development of economic, environmental and social benefits, price of boiler 3 tons.
