Effect of process variables on wastage in fluidized bed combustors: criteria for test procedures

The Mechanism of Char Ignition in Fluidized Bed Combustors

Knowledge about ignition processes of coal in fluidized beds is of importance for the start-up and dynamic control of these combustors. Initial experiments in a transparent fluidized bed scale model showed the existence of a considerable induction period for the ignition of char, especially at low bed temperatures (e.g., 800-950K for bituminous coal). This paper focuses on char-ignition delay a...

Effect of Process Variables on Growth Kinetics of Lactose Particles in a Wet Spray Fluidized Bed Granulator

Advanced Process Control for Fluidized Bed Agglomeration

Fluidized bed agglomeration is an advanced technology to produce spherical coarse-grained material of uniform size ready for sale without any need for post-treatment. This study discusses the possibilities and appropriateness of an intelligent control method such as a fuzzy logic controller in simulating and controlling fluidized bed agglomeration performance. Modeling and simulation was perfor...

Cost Function Formulation and Realization Methods for Optimum Control of Fluidized Bed Combustors

The Fluidized Bed Combustion (FBC) technology differs basically from other combustor types, one example is the double role of air flow: combustion and fluidization. Because of such differences, the well proven classical combustion control methods can not be used effectively for FBCs. In this paper, the task of combustion control will be formulated by means of a cost function. A general form of ...

Generation Process and Performance Evaluation of Engineered Microsphere Agarose Adsorbent for Application in Fluidized-bed Systems

In this research, the generation process of engineered microsphere agarose adsorbent has been explained that has surfaces with different active sites to adsorb protein nanoparticles into the fluidized-bed system. Also, excellent selectivity of protein nanoparticles, high adsorption capacity, and fast equilibrium rate through the eco-friendly polymeric adsorbents were vital aims in here. Hence, ...
