After DABONN's technical staff analyzed the user's on-site needs, it was determined to provide them with 2 integrated condensing gas steam boilers (WNS4-1.25-Y.Q).
Wuhan Yudahua Group Co., Ltd. is a cross-industry, diversified, comprehensive and export-oriented enterprise group that mainly produces cotton textiles and integrates woven and knitted home textile installations and automobile decoration. In 2017, the group expanded its textile processing and production scale and added several new production lines. The group's original steam boilers were unable to meet the growing demand for orders and urgently needed to purchase new steam boilers.
When choosing a manufacturer to provide steam boilers, I was attracted by DABONN's boiler equipment which can continuously output high-quality steam, and decided to cooperate with DABONN. After DABONN's technical staff analyzed the user's on-site needs, it was determined to provide them with 2 integrated condensing gas steam boilers (WNS4-1.25-Y.Q).
In this cooperation, DABONN left a deep impression on us with its responsible work attitude towards users. Our furnace workers were not very skilled in operating boilers, so DABONN specially sent professional technicians to guide us on-site on installation, commissioning, and Training to ensure that our boilers can operate the boiler well in the future.

This type of steam boiler has high steam quality and can significantly improve the dyeing and drying processes during textile processing. Since the processing plant consumes a lot of steam boilers, the steam boiler provided this time uses condensation waste heat recovery technology to re-absorb the latent heat part of the high-temperature flue gas.
This can not only improve the quality of textiles and production efficiency, but the thermal efficiency of the boiler can also reach 98%. Reduce labor and boiler operating costs, achieving multiple benefits with one stone.
In the system of oil-fired and gas-fired boilers, the condensing heat exchanger is the corresponding waste heat recovery and utilization equipment installed at the end of the boiler. If the flue gas is around the heat transfer surface, the corresponding near-wall surface temperature will gradually drop to the dew point temperature, which is accompanied by the cooling and condensation process of the water vapor, thereby releasing the corresponding heat and conducting the heat to the interior through the heat transfer surface. The specific working fluid is used, and then the heat in the exhaust gas is collected again, so as to achieve the purpose of energy saving and environmental protection of the system.

The boiler regularly discharges sewage or waste hot water whose pressure is higher than that output by the regular blowdown expander and separates secondary steam and waste hot water through decompression and expansion. The secondary steam can be discharged into the atmosphere or used as a heat source, and the waste hot water is generally discharged into the sewer system through the sewage cooling pool. In this way, the recovery of secondary steam and waste hot water can be used as a heat source, and a part of the heat loss caused by the boiler blowdown can be recovered, and the efficiency of the boiler can be improved.

Corner tube boilers use boiler coal injection technology. After the fuel is ejected in the hot air, it goes through multiple links such as ignition, combustion, coal ash separation, re-contact and combustion, etc. to generate flue gases that enter the boiler. The flue gases are exchanged with each other through water pipes and superheated pipes. After heat transfer, it turns into water vapor and enters the steam turbine to generate electricity. Because the corner tube boiler fully contacts the hot air and the combustion material, the heat energy is maximized, so it has the advantages of high thermal efficiency, energy saving, and environmental protection.

The continuous blowdown expansion vessel is connected to the continuous blowdown port of the boiler. By decompressing and expanding the continuous blowdown of the boiler, the blowdown is separated into secondary steam and waste hot water by adiabatic expansion, which is expanded and depressurized in the expander. , heat exchange and then discharge, secondary steam is led out by special pipeline, waste hot water is automatically discharged through floating ball liquid level valve or overflow regulating valve, and heat energy can be recovered and reused.

The low nitrogen steam boiler is a boiler shell type full wet backflow three return fire tube structure, The flame burns under slightly positive pressure in the corrugated furnace with high combustion thermal efficiency. The corrugated furnace can be fully extended according to the temperature, and the heat transfer area can also be increased. The second return journey adopts the threaded pipe structure. which improves the heat absorption intensity of the boiler. effectively reduces the smoke exhaust temperature. saves energy reduces consumption, and is economical to use. The third return journey adopts the big smoke tube technology. which can effectively reduce the smoke resistance of the boiler. improve the combustion efficiency of the burner. and reduce the operating noise of the burner. There is enough steam space in the upper part of the boiler, coupled with the use of advanced and reasonable steam separation devices. the steam quality is quite stable.
