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 integrated condensing gas steam boiler is one of DABONN's star products. Whether it is the design structure, components used, flue gas emissions, or thermal efficiency, it can withstand the test of all parties.
The energy efficiency inspection and testing by the Thermal Energy Testing Center of the Special Inspection Institute shows that all performance indicators are higher than the design requirements and have reached the advanced level at home and abroad.
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 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.

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.

Electric steam boiler is a new type of electric heating equipment that converts electrical energy into heat energy. Its design also follows boiler safety supervision regulations and industry manufacturing standards. The electrical components of electric boilers adopt well-known brands such as Siemens, Schneider, ABB, Chint, etc., which completely eliminates users' fear of electricity and leakage.

A corner tube boiler is a natural circulation water tube boiler. It differs from other water tube boilers in that it has the characteristics of a water-steam cycle. The pre-separation of heating steam and steam-water mixture occurs outside the drum in an unheated downcomer. This type of boiler is called a corner tube boiler.

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.

DZL type quick assembly boiler is a single drum longitudinal chain grate boiler. It is suitable for burning molded biomass fuel, and can also burn pure coal and molded biomass fuel. There is an economizer at the rear. The discharged ash and slag can be directly used as farmyard fertilizer, which is an efficient, energy-saving and environmentally friendly product. It is equipped with a drum induced draft fan for mechanical ventilation and a spiral slag discharging machine for mechanical slag discharging. The control and monitoring instruments are complete, making the boiler operation safe and reliable.
