water balance
Thread Content
Horizontal balance of water-coal slurry gasifier: Establish the horizontal balance equation for the gasifier: Water in the coal slurry + Water added to the quench chamber (FIC1310) = Water discharged from the quench chamber (FIC1304) + Gaseous water in the water-gas mixture (Gw) + Liquid water in the water-gas mixture (Xw) + Water equivalent of hydrogen and methane in the water-gas mixture + Water contained in the coarse slag. This is the equation regarding the horizontal balance of the gasifier as presented in the second issue of “Western Coal Chemical Engineering” in 2003; there are obvious missing terms in this equation, yet it was still published. Do you know which materials were overlooked?
For the hopper pump, does the water used for stamping the hopper count as well? What about the water used for pressure relief, and the water used to clean the hopper? Haha, the amount of water is quite minimal.: Is there still water left after coal and water are exposed to high temperatures? Isn’t it to produce CO+H2? How to explain the water in coal slurry?

In my opinion, the equilibrium equation for the stable operation of a gasification furnace is as follows: Gaseous water in the gasified gas + Quenching water + Water in the siphon loop = Black water in the quenching chamber + Gaseous water in the raw gas + Liquid water in the raw gas + Water in the slag exiting the quenching chamber. This is how I calculate it; I’m not sure if it’s correct Please give me some advice.
This calculation mainly overlooks the fact that the coal in water-coal slurry also contains hydrogen.
Does that mean it’s no longer called water balance, but rather hydrogen element balance! ?
Water balance is a relatively complex calculation process, involving internal water and external water in coal, as well as hydrogen. The amount of hydrogen produced in the furnace, and the hydrogen remaining in the coal ash. All of these must be taken into account. However, as mentioned above, practical production is sufficient; to truly calculate the water balance, it is necessary to study the reaction process.
