81-9 type CFB boiler have been analysed by using SPSS software,obtaining the relational expression of oil-gun output,air flow rate,and bed pressure affecting the temperature rise rate of bed layer,as well as the relational expresion between the particle size of bed materials and the starting-up time.
81-9型CFB锅炉的起动特性进行了分析,得出了油枪出力、风量、床压对床层温升率影响的关系式及其床料粒度与起动时间的关系式。
补充资料:床层塌落技术
分子式:
CAS号:

性质:在流化过程中,突然停止通气,床层便从流化状态经过收缩而回复到固定床状态,这个方法称床层塌落技术,是由我国郭慕孙院士提出的。这是一个从固定床变为流化床的动态逆过程。通过测量这一过程料面、压力、颗粒速度随时间变化等关系,可以判别各类物料的流化特性、测定流化模型参数。
