Why are domestic furnaces so good? Where do the data come from? Is Texaco’s feed rate really only 1,000 t/d?
Reply to 1# 196408: I would like to ask about the power consumption of space furnaces and GSPs. Does your data show that space furnaces consume much less electricity compared to GSPs? Could you give a brief introduction? Additionally, the space furnace seems to have been developed based on the GSp furnace design; why is the technology of the space furnace considered mature, while that of GSp is considered only moderately mature? Thank you. Please give me some advice
