How can the slag production and fly ash volume of a gasification furnace be determined? Can it be calculated?
Although I don’t know how to calculate it, it must be possible to do so; you can contact the design institute for help.
Under design conditions, the amounts of slag and fly ash can be calculated, but in actual production, apart from the amount carried away by the syngas and the amount that adheres inside the furnace, these amounts are also affected by factors such as load, pressure, temperature, and the oxygen-to-coal ratio
The slag and fly ash produced in the gasifier are primarily determined by the ASH content in the feed coal, as the carbon conversion rate of the effective coal in the gasifier is already quite high. In some literature, the ratio of fly ash to slag is approximately 3:7
It can be calculated based on material balance, but there is still a certain gap between actual production and theoretical values; theoretical data can only serve as a reference.
The amount of slag can be calculated, while the amount of fly ash can be determined through sampling and analysis.
How is the slag production amount in water-coal slurry gasification calculated?
What processing method do you use? The key factor is the ash content of your raw coal; from this, the total amount of slag can be calculated. Coarse slag accounts for around 80% of the total amount, while fine ash makes up about 18–20%. The residual carbon content is very low – the ash content in the syngas is less than 1%. There is also little scaling on the pipes, and the solid content in the ash water is similarly low, accounting for about 0.2% of the total ash content. A lot of data is calculated during actual driving; these calculations are carried out frequently to understand the production status, the level of skill in operation, etc. It is also necessary to regularly calculate consumption levels.
The slag production volume of the gasifier is related to the ash content in coal, the carbon conversion rate, and the amount of fly ash entrained
I have a way; I’ve calculated it before. Please contact me
The amount of slag and ash produced by a gasification furnace varies depending on the type of coal used, as different coal types have varying carbon content, ash content, and various other components. It is necessary to conduct analyses on coal samples in order to determine these values; it is particularly difficult to make such calculations when using mixed coal in some gasification furnaces.
