Operation when coal water slurry gasification ash melting point is high
Thread Content
How to operate when the ash melting point of coal is high. Can the coal slurry concentration be slightly adjusted?
First, the load control should be lower. Generally, the ash content will not be low even if the ash melting point is high, thus reducing the slagging load of the system.； Second, pay attention to adding an appropriate amount of limestone to reduce the ash melting point as much as possible. ； Third, the furnace temperature control should be 50% higher than the ash melting point.℃ ； Finally, if the melting point of the ash is higher than 1500°C, do not use it, as the refractory bricks will be too much!
Wealth + 6 points (* aodouzi) Haha, reducing the coal slurry concentration means reducing the load. Don't understand what it means?
Lowering the concentration means lowering the carbon/oxygen ratio, which is equivalent to lowering the load.
Load reduction during normal production is considered an accident. We slightly lowered the concentration of coal slurry by 1 percentage point. Will it play a certain role? Is this possible in normal times?
If the ash melting point is high, can production still be normal? Be careful when the ash melting point fluctuates widely.
