What are the maximum sizes that the diameter of the coal slurry tank and the mixing capacity can have?
Thread Content
I’m working on a new project that uses coal slurry gasification; the coal slurry tank needs to have a diameter of 12 meters and a height of 18 meters. Is it possible to use agitators of this size? The largest agitators I’ve used had a diameter of 8.5 meters. Additionally, what should be the design of the bottom part of such a coal slurry tank? What type of agitator should be used at the top of the tank, what do those agitator blades look like, and how is fixation at the top achieved? ----- Please don’t suggest that I contact agitator manufacturers directly; what I need are actual examples of how this is implemented in real-world construction projects.
Your question is interesting, but it’s hard to answer. Could you provide the parameters of your medium as well as the required linear speed for stirring? The diameter of the sedimentation tanks that I am aware of ranges from 6 meters to 150 meters, while their height ranges from 3.5 meters to 5.5 meters. This is the first time I’ve heard of something so complex; besides, are the difficulties and costs associated with civil engineering work acceptable?
At a glance, it’s clear you’re not involved in water-coal slurry gasification production
Oh, no, that’s not the case. I work in the coal processing industry. I’m sorry for causing you any inconvenience
I wonder how well your devices are selling? Is it for screening equipment?
It depends on the size that the mixer can achieve; the larger the diameter of the slurry tank that can be made possible by the mixer, the better. It is advisable to contact several well-known mixer manufacturers to find out which of their models offer a longer operational lifespan while still meeting the minimum requirements for use in gasification coal grinding systems. Both factors need to be taken into account in order to select the most suitable diameter for the slurry tank.
I know what you’re saying, and I’ve also contacted well-known mixing machine manufacturers; they said the maximum length they can achieve is 18 meters. But the specific performance and usage effects are unknown. Just to be safe, I’ll go with the conventional mature design.

At present, most of the coal slurry tanks in use are designed with a diameter of less than 8.5 meters and a height of less than 14 meters; to store more coal slurry, the common approach is to increase the number of such tanks. This has also determined the current specification capacity of the coal slurry mixer. If the diameter of the slurry tank is 12 meters, it needs to be redesigned; there may be no existing examples from the industry that can serve as a reference for you. I think the slurry tank is a device that operates at normal pressure and at low speeds, so there’s no need for excessive concern. As long as the mixer manufacturer can produce mixers of a larger size, there should be no problems and the risk is low. Currently, for 8.5-meter coal slurry tanks, the diameter of the lower impeller blades is 3.25 meters; for 12-meter coal slurry tanks, manufacturers are able to produce lower impeller blades with a diameter of 4.25 meters, which I believe meets the requirements. There has to be a first time.
Our project uses powder coal gasification, a sedimentation tank with a diameter of 24 meters, and a sludge scraper.
