This type of boiler is based on the traditional steam boiler, adding a design concept of integrated waste heat utilization.
A condensing recovery device is added to the tail of the boiler to recycle a large amount of latent heat in the flue gas, which greatly improves the overall efficiency of the boiler and prolongs the service life of the boiler.
Condensing and low nitrogen fuel gas steam boiler is a boiler shell type two-return firework tube structure with a full wet backflow. The flame burns under micro-positive pressure in the corrugated furnace tank, which has high combustion thermal efficiency. The wave tank 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. 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.

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.

As the most important auxiliary equipment in boiler equipment, the quality of the burner will directly affect the operating efficiency of the boiler and the emission of nitrogen oxides. DABONN is an integrated (split) burner designed and manufactured in accordance with relevant international and domestic standards. It adopts a multi-stage combustion method and covers a wide range of furnace types. It can be used in water tube boilers, fire tube boilers, modular boilers, and central return types of boilers such as burning boilers.

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.
