Urgent request: specifications for gas-producing coal blocks, please help!
Thread Content
We use lump coal to produce hydrogen; the design team did not provide specifications for bituminous coal, only stating that it is high-quality bituminous coal with a carbon content of 76%. I would like to ask the experienced members here: what are the specifications for the lump coal used to generate gas? Which indicators need to be measured? How to test it? Are there any **standards** for implementation? I would be very grateful if you could offer some advice!
Dude, you’ve come to the wrong section. Just so you know, the size of each coal lump is 8 centimeters, and the analysis parameters include fixed carbon, sulfur content, volatile matter, and moisture.
The T1, T2, and T3 temperatures are also important indicators. Ash content.
Blocks of 35–75: fixed carbon, volatile matter, ash content
Generally, the requirement is around 2 to 15 centimeters; it’s not very strict in this regard, but the particles must be uniform! For burning small particles, low air pressure and a long blowing time are generally used, while the opposite is true for large particles!
