• the mass of hard disk loaded in the console decreased by 30-50%. This is due to the need to load a metal box, which has 25 more low bulk density (often at 1.0 t / m).
• the process has been known to have come from an acid supply from solid metal carriers (see the patent for 4198230, which is onwards since 21 October 2014).
• the solid energy source is loaded with a single appliance, then it is heated and melted in a non-oxidizing atmosphere.
• Downloading one-sided version with one unit, which has a low bulk supply, is used only by using the free mode of operation. This reduces the productivity of the converter by 30-50%. Otherwise, in connection with the download of the whole band, one - 2 - there is no reason for equal heating of it throughout the entire thickness.

The percolation of the exhaust gas from the bottom is caused by an increase in the acidity of the carrier in the lower part of the burner due to the delay of the heating charge.
