Please explain: dynamic combustion, diffusion combustion, transitional combustion

Based on the different influences of chemical and physical conditions on the combustion rate, combustion can be divided into three categories: (1) Dynamic combustion: At lower temperatures, the rate of chemical reactions is slow, while the rate of physical mixing is relatively fast. In such cases, the combustion rate is primarily determined by the chemical conditions, namely the temperature inside the furnace. This type of combustion is referred to as dynamic combustion, or combustion in the dynamic zone. (2): Diffusion combustion: When the temperature is high, the chemical reaction rate is fast while the physical mixing rate is relatively low, the combustion rate depends mainly on the diffusion of oxygen within the furnace to the fuel. We refer to this type of combustion as diffusion combustion, or say that the combustion takes place in the diffusion zone. (3): When the temperature inside the furnace is suitable for the mixing conditions, the combustion rate depends both on the temperature and on the mixing and diffusion of oxygen with the fuel. We refer to this type of combustion as transitional combustion, or say that the combustion is in a transitional zone.
