双室内循环流化床煤气化系统的冷态实验研究

本文发展并建了双室并列流化床煤气化系统的冷态模型。在此基础上，对影响气化系统操作的两个主要因素－两流化床之间颗粒物料的循环技术及流化床床层的膨胀特性进行了实验研究。

A Cold-state Experimental Study on a Gasifier with Two Fluidized Beds

This paper describes the setting-up of a cold-state model of a gasifier with two fluidized beds. An experimental study was performed of the two major factors affecting the operation of the gasifier,i. e. Particle circulation technique between the two beds and fluidized bed expansion characteristics. As a result I obtained were the characteristics of the particle circulation between the two beds and the fluidized bed expansion under different operating conditions. Also analyzed were the various factors which influence the gasifier operation, such as fluidization speed I bed static height. auxiliary gas flow rate,etc.
