Does the type of coal affect the control of the quench chamber liquid level?

Does the type of coal affect the control of the quench chamber liquid level? For example, the ash melting point is too high, or the calorific value is too high.
The type of coal varies, which in turn affects the temperature of the gasifier, but the liquid level in the quench chamber should not be affected by this, right?

There should be; since coal has a high ash content and a high ash melting point, the heat load is high, which results in more water being carried away, thus affecting the liquid level
It affects the liquid level in the gasification furnace, as certain dimensions are specified in the design of components such as the slag outlet and downcomer. Changes in the type of coal have a direct impact on this; for example, when coal with a high ash melting point is used, the gasification temperature must be increased. As hot gases pass through the slag outlet and the bottleneck in the downcomer, they rapidly vaporize the water in the quenching chamber, turning it into saturated steam. This results in an increase in the total volume of gas and a faster gas flow rate. As a result, some of the water in the quenching chamber is carried away, and additional water is vaporized there as well. Therefore, the liquid level in the quenching chamber of the gasification furnace drops.
