Actually, it is always the transfer of heat from bed to surroundings.
实际上，传热往往是由床层至周围。

Combining with particle impact heat transfer model, DEM method is also used to systematically simulate the heat transfer process in fluidized bed at the level of particle.
将DEM方法与颗粒碰撞传热模型结合，在颗粒层次上对密相流化床内的传热过程进行了较为系统的数值研究。

The combustion and heat transfer in CFB boiler are related with the bed material, while the bed material is formed during the coal combustion, fragment and attrition processes.
