Lignite briquette process
Thread Content
I wonder if everyone is familiar with the lignite briquette manufacturing process? I saw in the coal chemical technology manual that black water pumps are used for this purpose I’m not sure about the technical situation Experts are welcome to discuss! ! !

I have a gentle question: is there a difference between briquetted coal and shaped coke?
Briquettes: formed under low pressure using binders, or without binders under high pressure. It only needs to be dried at 400-500 degrees; high-temperature carbonization is not required. Pneumatic coke: It is formed under low pressure using a binder, or without a binder under high pressure, and then carbonized at high temperatures of 900–1200 degrees.
Give it a thumbs up; I hope everyone will discuss it! ! !
Lignite is a coal with low calorific value, and it is better suited for use in non-fuel applications. . For example, in lignite, humic acid is extracted, among other things. Make activated carbon, carbon molecular sieves, etc.
Not bad, I hope everyone will give it a try.
The technology for producing multi-purpose clean fuel in the form of \"briquette semi-coke\" from lignite is a relatively mature one. Through further processing, the quality of lignite is improved, resulting in a calorific value of over 5,000 calories and a moisture content reduced to 3%–5%. Such briquettes do not weather or catch fire on their own, which facilitates storage and transportation; they allow for an increased transportation range and storage duration, thereby expanding the sales channels for lignite. Moreover, the production of briquette semi-coke generates by-products such as tar and methanol, which also possess high economic value. Many enterprises have already started doing this; there is the project in Hulunbuir City to produce 200,000 tons of lignite briquettes and 10,000 tons of coal tar per year, as well as the Shenhua Hulunbuir coal, electricity, and lignite upgrading project, which includes two production lines capable of manufacturing 500,000 tons of upgraded lignite briquettes per year......
Hello, I recently have a project involving the production of briquettes using lignite as raw material, but I don’t know much about the techniques involved in this area. After seeing your post, I hope to get your assistance. If you are interested, please contact me at 13835131520
**Is there any relatively mature briquette technology available? We need it urgently!
Around 500 degrees, it’s not just drying – there should be some carbonization as well. So what should be done with the volatile flammable gases that are produced as a result of carbonization?
Lignite drying is currently used quite frequently, but there is no separate process for compressing lignite into shapes; we are researching the compression of lignite semi-coke and have achieved some results.
