Project Description
CWM-Ⅲ Serial water-coal-slurry stove
CWM-Ⅲ Serial water-coal-slurry stove
CWM-ⅢSerial water-coal-slurry stove Advantages
1.Good controllability and high automaticity Because water-coal-slurry is similar as petroleum, it can be pressurized in pipes, spray burnedas oil.
2.The combustion fan and compression pump are adopted frequency control of motor speed, which can be operated easily as oil burning equipments. High combustion efficiency and large output (combustion efficiency is about 99%).
3.Good thermal insulation effect, energy conservation.
4.High dust collection efficiency.
5.Long working life.
Technological process of water-coal-slurry producing ceramic powder.
Storage→Filtration vibrating screen→Servo tank→Screw pump→Water-coal-slutty stove→Hot air pipe→Dust collector→Spray dryer.
