The QXX low-speed internal circulating fluidized bed hot water boiler adopts the new double-vortex low-speed circulating fluidized bed technology, that is, the water circulation technology of forced circulation plus natural circulation and injection, adopts the horizontal water-cooled separator separation technology, and the boiler is arranged in the horizontal π type of double boiler barrel, with the low-speed circulating fluidized bed combustion technology of upper and lower boiler tubes and convective tube bundle.

The boiler is adjusted through the furnace structure.

With the proper introduction of secondary air, combined with the flue gas secondary circulation introduction device set in the primary air of the boiler and the desulfurization method of adding limestone in the furnace, low pollutant emission technology is achieved, making the overall structure of the boiler compact and simple, high combustion efficiency, safe and simple water circulation and low resistance, high heat transfer efficiency of the boiler, low cost, energy saving and environmental protection.

High combustion efficiency, high efficiency, energy saving and environmental protection, wide application of coal, bituminous coal, lean coal, anthracite, coal gangue, slag, etc. can be burned, convenient for users.

Comply with environmental protection, production specifications, accurate low-temperature graded combustion and air distribution. SO2 and NO2 have ultra-low initial emissions and superior environmental performance.

Clean combustion, low NOx emissions, and can be directly added to the furnace to achieve efficient and low-cost desulfurization, conducive to the improvement of atmospheric environment.

The slag can be used comprehensively, which increases the economic benefit and improves the surrounding environment. Small footprint, saving boiler room investment.
