Blockage at the cone bottom of the primary tar separator
Thread Content
Seeking advice: How is the operation of everyone’s primary tar separator? Is there a lot of coal dust at the bottom of the cone? How to exclude the system? An excess of coal dust directly affects the operation of the mixing motor. How can this be resolved?
Pre-filter dust removal device. Or increase bottom discharge.
Hello, what does a pre-dust removal device look like? Increasing emissions is also difficult; no one wants to transport dust-containing tar, as everyone prefers to transport tar and light oil. How is the dust-containing tar dealt with where you are?
There is a lot of coal dust at the bottom of the cone in the primary tar separator – is the heat exchanger ahead blocked? The root cause is likely the high dust content in the coal fed into the furnace; addressing the issue at its source would be better. Treating it after it reaches the gas and water treatment system is more complicated. First, it’s necessary to determine what is causing the high amount of coal dust in the water system – whether it’s due to poor mechanical properties of the coal or an excessive amount of pulverized coal in the raw material. If the coal fed into the furnace contains a lot of pulverized coal, considering the installation of a screening device before the furnace might be a good solution.
It operates stably with no blockages occurring. Keep the coal particle size used in the gasifier between 8-80 mm, and discharge the dust-containing tar from the primary tar separator once a day.
Can dust-containing tar be discharged once a day? Was it loaded on site, or queued up for some kind of equipment? It takes more than a week for a truck to come and pick up the dust-containing tar here.
It needs to be discharged once a day and loaded for sale. In 1 week, 3-4 trucks worth of equipment need to be installed per unit
