A boiler hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The main purpose of the hydrostatic test is to identify the tightness and compressive strength of the pressure components of the boiler, including but not limited to welding lines, flange joints and tube expansion joints, and visually observe the deformation of the pressure components. Practice has proved that the boiler hydrostatic test can detect defects in boilers, and the corresponding measures can be taken accordingly. Therefore, it is an important step and means to ensure the safe operation of the boiler.
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%
Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang. The body and the middle partition wall of ZOZEN DHL series corner tube hot water boiler adopt membrane water wall complete sealing structure, which greatly reduces the boiler heat loss and improves the boiler thermal efficiency. Meanwhile, the flag heating surface of this series of boilers is designed with patented technology of the same smoke velocity in variable cross-section, so that the flow velocity of the smoke in heated surface between the high temperature zone and the low temperature zone is uniform, reducing the ash accumulation and increasing the heat transfer co-efficiency.
ZOZEN SZL series coal-fired (biomass-fired) boilers have wide fuel adaptability, applicable to a wide range of fuels including all kinds of coals and biomass particles; they have the charactics of sufficient output, safety, high effciency and high degree of automation. Meanwhile, this series of boilers is equipped with an advanced control system, which is safe and worry-free.
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...
For decades, ZOZEN boilers has always guided the manufacturing quality of industrial boilers and established the technological standards of blanking digitization, automation of welding and assembly moulding. The full-automatic CNC tube bending production line greatly improves work efficiency and quality, providing a powerful guarantee for creating first-class products.
