Do you know what the principle and function of gasification are in a gas generator?
1. Empty layer: a space that mainly collects gas generated by the gas generator.
2. Drying layer: endothermic reaction to dry the moisture in the coal.
3. Pyrolysis layer: The coal blocks undergo low-temperature carbonization here, which is the case of pyrolysis gas. It is the degradation of minerals in completely anaerobic conditions or with very limited oxygen provided so gases do not occur in large quantities.
4. In the gasification layer, there is no oxygen in the reduction layer, and it reacts in the oxidation zone to form Nco.
5. The combustion layer enters the gasification agent from the bottom of the furnace. As it passes through the ash layer, it is heated, and the heated gas enters the bottom oxide layer, where it reacts with the hot carbon to produce CO2 to dissipate heat. Since oxygen restricts combustion and the oxygen supply is insufficient, incomplete combustion reactions occur simultaneously, producing CO and releasing heat at the same time. The temperature in the oxidation zone can reach 150-1200 degrees Celsius, and the combustion reaction in the oxidation zone is carried out.
6. Ash and slag layer. The ash and slag produced by the coal gasification reaction process in the furnace are covered in the furnace to form an ash layer.
