Technical features of industrial pulverized coal boiler:

High thermal efficiency

The combustion efficiency is greater than 98, reducing the thermal loss of mechanical incomplete combustion, and the boiler thermal efficiency can reach 90%.

The environmental effect is obvious

(1) a double alkali desulfurization filter was adopted, and the concentration of emission was low in 302.

(2) the burner adopts the low nitrogen burner, the temperature field is even and the combustion process produces a low content;

(3) the furnace is equipped with three times of wind, adjusting the wind quantity according to the burning conditions, effectively reducing the generation of the rib and eliminating the black smoke;

(4) the tail adopts advanced cloth bag filter, and smoke (powder) dust emission concentration is low;

(5) adopt airtight feeding system and dust cleaning system to reduce dust pollution;

High safety

The guarantee condition of high efficiency coal powder boiler system to avoid safety concerns is scientific and perfect technical system and advanced prevention means; Adopt a highly efficient and reliable ignition controller to prevent the ignition of ignition in the furnace and complete the fire-extinguishing chain protection; The electrostatic grounding and 2 protection measures are adopted to prevent the spontaneous combustion and explosion of coal powder.

Manipulation of the simple

The boiler system is highly integrated and equipped with a fully automatic intelligent monitoring system. The boiler operation realizes automatic control and adjustment, and the parameters are automatically collected, fault alarm and security chain protection.

The boiler is compact and reduces the height of boiler room

There is no need to heap coal yard and ash field, the area is small.

Advantages of industrial coal dust boiler:

(1) coal concentrate supply: the coal powder is consolidated and supplied by the pulverized mill, and the quality of coal powder is stable;

(2) friendly work environment: the whole system is closed and operated, and the automatic pneumatic conveying can be used for coal concentration and ash free running;

(3) the energy saving is significant: the combustion of coal powder is sufficient, the boiler operation efficiency is high, compared with the chain furnace, the coal burning boiler section coal more than 30%;

(4) clean emission: the low temperature combustion environment can realize the desulphurization of the furnace; The burner adopts the low nitrogen burner, the temperature field is uniform, the combustion process produces NO. The tail adopts advanced double alkali desulphurization and cloth bag dust collector, and smoke (powder) dust emission concentration is low. The fly ash is discharged through the airtight system without secondary pollution.

(5) boiler control is simple: the system can be realized namely stop, cut off point fire source for normal operation; Cutting off the coal powder supply can realize the stopping furnace; The system automatically monitors and adjusts the running parameters to keep the system in the best running state;

(6) high cost performance: low operating expenses, and the equipment investment can be recovered in a short period of time by coal.

(7) save land: the boiler room has cancelled the traditional coal yard and slag fields, and occupies a small area.
