Further edit: Yes I know steel furnaces take the same energy as stone furnaces. 1 belt of coal can supply 666 stone furnaces, to make yellow belts of plates per minute. The same belt of coal can supply 666 steel furnaces to make belts of plates per minute. I used the number 24 because it's nicely divisible by 4, unlike
As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the twostage pulverizing sec tion.

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w). With the ...
