Drum Type Rotary Ash Cooler Wearing Resistance For High Temperature Slag

Rotary ash cooler,Its material is 1Cr18Ni9Ti and Q235,for the CFB boiler:

Drum Type Ash Cooler:

General Introduction:

The drum type ash cooler is a drum type heat exchanger used for cooling the bulk material, the structure and heat exchanging process of which are different from that of the usual heat exchanger. For the drum type ash cooler, three methods of heat transfer as thermal radiation, conduction, and convection are working in the same time, and primary cooling medium is water and the secondary is air. It is a high efficiency ash cooling equipment, which is designed to meet the requirement of the large-volume CFB boiler. The drum ash cooler consists of drum, ash filling device, ash discharge device, drive device, transmission device, cooling water system and electric control device, which is specifically used for the hot ash cooling of CFB boiler

Main Technical Parameter:

The model of ash cooler is GTL (S) D - n ×L (left or right), among which, D stands for drum diameter (mm), including 700mm, 800mm, 1000mm, 1200mm, 1500mm, 1800mm, and 2000 mm; n stands for the capacity (t/h); L stands for the distance between inlet and outlet (mm). According to the different installation positions, the ash cooler can be classified as left type and right type, facing the ash cooler outlet, it is left type if the motor on the left and is right type if the motor on the right. The length of the ash cooler is not fixed, which is usually related with the capacity, ash temperature, and the rated distance between the inlet and outlet. The output of ash cooler is 0 - 80t/h. And the cooling temperature is 80 - 150℃

Installation Instruction:

Place the ash cooler on the flat ground with bearing capacity higher than 6000Pa, (anchor bolt is not necessary), then place embedded iron on the ground for the four corners of the ash cooler stand, and weld the locating iron on the embedded iron to prevent moving when the ash cooler is set on the right place

When the foundation is higher than the ground, pour two longitudinal or four transverse plain concrete strip foundations with strength more than C30 on the ground. When the left type and right type ash cooler are arranged next to each other, for the convenient maintenance and repair, the drive motor should be arranged at the outer side, which means put the left type ash cooler at the left side, and the right type at the right side.

GTL series single drum ash cooler

Advantages:

1,Large output, which can reach 80t/h at the maximum

2,Large internal space, which is convenient for inspection and easy for maintenance with a low cost.

3, Rotary joint with external bearing for water system,High pressure resistance, no leaking, and long service life

4, High-temperature resistance compensator

High temperature resistance, and the temperature≮1200℃

Large compensation, which can satisfy the X and Y direction expansion of 300MW, and 600MW CFB boiler

Good wearing resistance, especially suitable for high temperature ash/slag condition, and the service life is no shorter than 2 years

Convenient to install, and easy to maintain.
