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.
The sub-cylinder is also called the sub-drum, which is the main supporting equipment in the steam boiler. It is widely used in power generation, petrochemicals, steel, cement, construction, and other industries. It can distribute the steam generated by the boiler to various pipelines. The pressure-bearing equipment of the sub-cylinder system belongs to the pressure vessel, and its pressure-bearing capacity and capacity should correspond to the supporting boiler. The main pressure components of the sub-cylinder are the head, shell material, etc.

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.

The SZL series double-drum vertical chain grate water tube steam boiler adopts a quick installation or assembly structure. For 4-6t/h capacity, it is a quick installation water tube structure and is fully assembled in the factory before delivery. For 6-35t/h capacity, it consists of two major components: the upper part is the heating surface, and the lower part is the combustion equipment. The high-temperature flue gas is directed through the convection heating surface and passes through an economizer and dust collector before being discharged.

Conden gas-steam boiler is a wok shell type with three backflow downstream pyrotechnical tube structure. The flame burns under micro-positive pressure in the corrugated furnace with high combustion thermal efficiency. The corrugator can be fully extended according to the temperature and the heat transfer area can be increased at the same time. 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 and reduces consumption, and is economical to use. The third return journey adopts the light smoke tube, which can effectively reduce the smoke resistance of the boiler， improve the combustion efficiency 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 device, the steam quality is quite stable.

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water flow rate and excellent water circulation system. Boiler heat absorption rate and thermal efficiency are high.
