After comparing many companies in the boiler industry, we decided to cooperate with Fangkuai Boiler and purchase a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
Midea is my country's national enterprise. As one of the world's top 500 companies, Midea has achieved very dazzling glory on the world stage. As a branch of Midea Air Conditioning, it has very strong market competitiveness.
In 2016, Hubei's air conditioners expanded their production lines due to market demand and needed to purchase steam boilers to provide kinetic energy support for the new production lines.
After comparing many companies in the boiler industry, we decided to cooperate with DABONN and purchase a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
The emergence of DABONN solved this problem for us in time. From the signing of the contract to manufacturing to transportation to our company for installation and operation, it only took Fangkuai 35 days to solve our urgent need.

The deaerator is one of the key equipment in the boiler and heating system. It is mainly composed of the deaerator tower head, the deaerator water tank, as well as the connecting pipe, and the external parts. If the deaerator's deoxidizing ability is poor, it will cause serious corrosion to the boiler's water supply pipeline, economizer, and other ancillary equipment, and the economic loss will be dozens or even hundreds of times the cost of the deaerator. Everyone must pay attention to the quality selection of deaerators.

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 SZS low-nitrogen condensing gas boiler is a double-drum longitudinal "D" type quick-installed water tube boiler. It consists of an upper and lower drum, a membrane water-cooled wall, a convection tube bundle and a flue gas condensation recovery device. After the fuel is burned in the furnace, the flue gas is discharged into the chimney through the convection tube bundle and the flue gas condensation recovery device.

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.

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.
