SCD pump apply to CFB boiler economizer bottom residue and the Office of coarse materials transportation.
2. Dense SCD running pumps
When the carrier launched a cycle, the control system will be activated interlock inspection cycle fully meet the conditions, when conditions are true, will trigger a transmission cycle, according to the following steps to run:

Step 1
Pump entrance dome and the exhaust valve is opened, exports dome valve closed. The materials will be under the effect of gravity into SCD pump.

Step 2
When the level meter for material sent signals the entrance pump and the exhaust valve closed dome.

Step 3
When all the entrance dome valve has been closed but sealed exports dome valve opened.

Step 4
Carrier air valve opened. Meanwhile, the SCD pump flow of air valve opened.

Step 5
Materials piped through to the target Ash.
