Cleanliness is the aim of heating in northern China, and several projects have reversed construction periods. It is planned to complete the upgrading of gas-fired hot water boiler equipment before the coming of the heating season in 2022-2023. Recently, many batches of gas-fired hot water boilers provided by ZOZEN Boiler for heating users have been delivered one after another.
ZOZEN normal pressure gas boiler is a horizontal wet-back type fire tube boiler, which adopts a large-threaded smoke tube and a corrugated furnace to increase the radiant heat absorption, strengthen the heat transfer effect and save fuel consumption, to achieve the goal of energy saving and consumption reduction. At the same time, the normal pressure gas-fired hot-water boiler adopts an intelligent control system, equipped with various safety interlocks such as overheat protection, protection against dry burning and water shortage, and leakage protection, which can supply heat and water stably for a long time.
The customer is mainly responsible for the central heating and operation of natural gas in Fanxian New District, and the heating area covers 39 old local communities. The heating boiler selected by the company is ZOZEN SZS gas-fired hot water boiler, which has the characteristics of energy saving, environmental protection and automatic operation, and provides comfortable heating experience for local residents.
ZOZEN Boiler provided a set of 46MW SZS series gas-fired hot water boiler for Luanchuan County Thermal Power in Henan Province. The boiler combustion chamber adopts the full membrane wall structure with a large radiation heating surface. There are also energy-saving devices at the end of the boiler, which can reduce the exhaust gas temperature and improve the overall thermal efficiency to 95% and above. In addition, with advanced combustion equipment, the boiler's nitrogen oxide emissions can be less than 30mg/Nm3. ZOZEN SZS series hot water boiler is energy-saving and eco-friendly and has a wide range of capacity, which can meet the demands of central heating in various places.
ZOZEN WNS series gas-fired hot water boiler adopts packaged structure, which is convenient and quick for installation to save a lot of basic construction costs for the enterprise. Its internal structure adopts large-diameter waveform strove furnace which can effectively absorb heat expansion to add the radiation heating surface and ensue the low emission of NOx with the advanced low-nitrogen burner to improve the fuel utilization. What's more, its thread smoke tubes have scientific pitch and depth to further strengthen the convective heat transfer and make boiler's thermal efficiency reach 95% and above.
CMU short for China Medical University, located in Shenyang, Liaoning, is a university jointly established by the National Health and Family Planning Commission, the Ministry of Education, and the Liaoning Provincial Government. The DHL series hot water boiler provided by ZOZEN is the second-generation corner tube hot water boiler. This return visit, ZOZEN carried out all-round maintenance for the boiler to ensure the safety and stability of its heating in this winter.
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.
