Product Details

The QXX circulating fluidized bed boiler is a newly developed circulating fluidized bed boiler by Yongxing Boiler

Fluidized bed hot water boilers can produce various types of coal fuels such as bituminous coal and lean coal

Full combustion reduces heat loss caused by incomplete combustion of fuel and improves efficiency

Improved combustion efficiency and thermal efficiency, reducing fuel costs. Better still

This boiler represents the latest direction in the development of circulating fluidized bed technology and has fuel capabilities

Wide adaptability, complete protective devices, high combustion efficiency, strong load adaptability

Characterized by a high degree of automation, it is widely used in the petrochemical and metallurgical industries

Mining, building materials and other industries.

The boiler body of QXX circulating fluidized bed boiler adopts a fully steel frame structure,

Composed of combustion equipment, water cooling system, separator, coal feeding device, economizer, and air

Composed of preheaters, steel frames, etc., the combustion chamber and separator are arranged in sequence backwards

Tail flue, etc. This boiler was developed on the basis of a bubbling bed, and

Compared to bubbling beds, bubbling beds have higher combustion efficiency, higher wind speed, and higher

The vulcanization speed has therefore rapidly developed worldwide.

Auxiliary equipment configuration:	Performance characteristics:	Burning particles can achieve cyclic combustion, improving combustion efficiency and achieving a combustion efficiency of 95% -99%.	The membrane type cold water wall structure is adopted on both sides of the furnace, which not only ensures the sealing of the furnace, but also improves the thermal efficiency.	The boiler can operate stably at low loads without the need to add auxiliary fuel.	The boiler has fewer mechanical transmission components and no buried heating surface, which extends the operating cycle of the boiler.	The fuel has strong adaptability and can be used as either smokeless coal, bituminous coal, or biomass pellets.
Greatly reducing the generation and emission of NOx, protecting the environment, and complying with environmental policy requirements.	29	1.25	130	70	85	Limestone can be added to the fuel to achieve economic desulfurization, achieving a desulfurization efficiency of around 90%.
The return system adopts a membrane water-cooled wall structure, which can absorb some of the heat carried by fly ash, reduce the temperature of fly ash, and prevent coking caused by secondary combustion.	29	1.6	150	90
