This is a schematic drawing of the 9.0 system, which shows the changes that have been made relative to my version with the 8.0
logo. The first is the raised tuyeres (approximately 20 degrees). Second, there is a change in the number of tuyeres - there are seven of them with a diameter of 8.2 mm. Third, this is a change in the bottom of the gasification chamber, namely, a removable bottom with a neck. The very bottom of the chamber and the neck are made with thermal gaps and are not rigidly fixed. Also added a heat shield and a movable grate. There is also a screen for keeping coals on the grate, which reduces the removal of large fractions from the core.
