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.
ZOZEN will held regular exchange training sessions. On the one hand, it helps employees to better understand the company's business, speed up the company's development process, and resolve any skills gaps. On the other hand, training can stimulate employees' confidence and improve their subjective initiative. Employees gained a lot from this gas-fired boiler knowledge training, laying a good foundation for upgrading higher quality products.
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%
In the petroleum industry, steam is the main factor affecting the energy consumption of enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. ZOZEN provided the company with SHL series field assembled water tube steam boiler. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler.
ZOZEN YQW series thermal fluid heater is simpler to operate. The thermal fluid heater is completely assembled before shipment, which is easy to install, debug and use. This series of gas-fired thermal fluid heater has the features of automatic operation and adjustment of combustion, high tank level, outlet temperature and flow rate. The inlet and outlet of this product adopt the flanges and flange cover structure at both ends to facilitate the installation and arrangement of the boiler room pipes.
ZOZEN YY(Q)L series vertical thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN YY(Q)W series horizontal thermal oil heaters adopt special processing technology, and have wide fuel adaptability, suitable for natural gas, coal gas, blast furnace gas, heavy oil, light oil, etc. They have the advantages of safety, high efficiency, energy saving and environmental protection, and the thermal efficiency is over 95%.
ZOZEN WNS series gas-fired (oil-fired) boilers adopt large diameter corrugated furnace for sufficient fuel combustion; euqipped with low NOx burner, the thermal efficiency is over 98%, and the ultra-low emission of NOx is easy to achieve.
