Problems with fixed-bed gas generation
Thread Content
As the title suggests, how difficult is it to increase the pressure for normal-pressure gas production in a fixed-bed reactor to 10 kilograms? How significant is it?
You’re an expert at Luchi Furnaces; how could you ask such a question? I think the difficulty lies in ensuring the sealing of the coal lock and ash lock in the gasification furnace; after all, it’s not acceptable for 10 kilograms of raw gas to leak out ； Furthermore, the steam decomposition rate decreases under pressure, resulting in an increase in wastewater volume and higher steam consumption. Meaning? It’s just an increase in the compression work required for 1 unit of oxygen, with a decrease in the compression work needed for 5 units of raw coal gas. When the pressure is increased by 10 times, the reaction rate increases by a factor of about 3, in proportion to the square root of that increase. The ultimate outcome is nothing but the development of the Ruhki furnace. That’s probably how it is; I’ve never done vaporization, so it’s just an inference based on the simple principles.
