Problems with the preheating water circulation in the oven
Thread Content
We have always said that the preheated water circulation in this furnace follows the path from the water seal tank to the slag pool, and then it switches to the path leading to vacuum flash evaporation; in some cases, the water seal tank is not used at all, and the preheated water pipeline goes directly to vacuum flash evaporation. This can reduce some operations; is it appropriate to do this?
I think that’s a reasonable approach; many manufacturers do it that way, and no problems have arisen. Why is the second floor unreasonable? ? ?
Many organizations do this these days; I think it’s quite reasonable
So if a water seal groove is installed, isn’t it then unnecessary? Does this also relate to the original design of the vehicle, and to the use of fire-resistant bricks?
Sure! There are several ways to preheat the furnace: 1. Through the water seal tank; 2. Through the startup heat exchanger; 3. Through true flash; 4. It can also be discharged directly into the slag pool. There are many methods available – it depends on what you choose to use! !
I think it depends on the circumstances. Generally, when the furnace is in operation, the liquid level in the gasification furnace is very low, essentially at the level where the black water exits the gasification furnace. There is negative pressure inside the gasification furnace, so the water flows out through the black water pipeline due to its own gravity. In the case of vacuum flash tanks that are located on higher floors, it’s not as easy to get the water to flow back into the vacuum flash tank solely based on the difference in elevation. For vacuum flash tanks designed on lower floors or even at ground level, it is feasible to monitor during furnace heating to ensure that there is a certain liquid level in the vacuum flash tank.
Well, we’ve been discharging directly into the slag pool all along. . . . . . . . . . .
Can it go to true flash during furnace drying? There’s no way to get past without conveying equipment; if one tried to go that way, it would probably backfire long ago
We can use true flash; when it comes to heating the furnace, it’s possible to bypass the water seal tank and use true flash directly, which also makes things easier later on when switching to system water circulation.
