company news about Preheat the fuel of the refractory brick

Preheat the fuel of the refractory brick, or the use of kiln exhaust flue gas temperature, the preheating of the 

combustion air to the appropriate temperature, the fuel and combustion air into the furnace combustion, into a portion of the physical heat, thereby improving fuel theoretical combustion temperature. The air preheating combustion of liquid fuel, can accelerate the gasification oil atomization, make oil combustion more completely, also can accelerate the combustion speed and improve the degree of completeness of combustion.
