WhatsApp: +86 18203695377Similar to dry air purges, dry nitrogen purges pull moisture out of the air within a test chamber, but, instead of using a desiccant humidifier, rely on ultradry nitrogen (which has a dew point of 70 degrees Celsius). When injected into an enclosed workspace, nitrogen expands and adds pressure, forcing the remaining moisture out of the chamber.

WhatsApp: +86 18203695377This indicates that the increase of SRI has a positive effect on the desiccation of coal slime. The reason is that the increase of SRI can accelerate the heat exchange between air and coal slime in the drying chamber and accelerate the desiccation process. Table 3 shows the D eff values of different L's when SRI is 600 W/m 2.
