The hot air can be recovered and used in other process operations. Compared with water granulation, dry granulation enables production of slag granules without water and significant waste heat recovery. Dry granulation of slags was first proposed more than 30 years ago and has been the subject of numerous studies [3, 4, 5, 6, 7].
Ecomaister-Hatch has recently developed and brought to commercial scale a reliable and simple dry slag granulation that allows for simultaneous energy recovery from slag. The current article …
from both bio-oil and steam [31, 32]. Thus, combining dry reforming with steam reforming (dry/steam reforming) can achieve negative CO 2 growth while achieving an adjustable H 2 …
To provide the necessary thermal energy demand for the drying step, instead of igniting torgas and biomass, recovered slag heat could be utilized. The energy demand to replace 5% of the necessary coke with biomass is 133 TJ/a and would be covered 8 times by BFS heat at 100% recovery (see Table 5 ).
The heat exchangers extract thermal energy from the slag and transfer it to water or oil. The first module cools the slag from the tapping temperature of about 1500 °C down to 850 °C.
For these reasons, and considering the typical HRE (heat recovery efficiency) values reported in the literature, a reasonable recovery would be 50% (thermal to thermal). With this, and using the weighted average enthalpy of all slags at 1.6 GJ/t, the effective thermal energy recovery from slag is ~ 0.8 GJ/t.
The non-crystalline and crystalline contents of original blast furnace slag are obtained by combining the X-ray diffraction results and mathematical treatment, and this …
To address the challenge of dust control during dry drilling of underground coal seams, a novel dust-collecting device for micron-size dust was designed and tested. To …
