From the scheme obtained in a few minutes after ignition, it is observed that the sintering process can be divided into six distinct zones: 1. Zone of Cold Sinter (60 to 100 degree Celsius) 2. Zone of hot Sinter (100 to 1000 degree Celsius) 3. Zone of intensive combustion of fuel (1000 to 1350 degree Celsius) 4.
