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...
متن کاملHydrodynamic Characteristics of Dry Beneficiation of Iron Ore and Coal in a Fast Fluidized Bed
Iron ore and coal are the two major important raw materials being used in Iron making industries. Usually ore fines containing around 5% Alumina are rejected due to higher proportion of alumina. Therefore, a technology or process which may reduce the alumina content by 2% by beneficiation process will be highly attractive . In addition fine coals with ash content is used nearly 12% is directly ...
متن کاملCost 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 ...
متن کاملfluidized bed drying characteristics of soybeans
the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...
متن کاملFluidization Characteristics of a Prototype Fluidized Bed Reactor
The fluidization characteristics of a prototype-fluidized bed laboratory reactor were understudied in order to investigate the suitable conditions at which the dehydrogenation reaction of butane could be carried out. To achieve this, a reactor with an effective volume of 1100ml was fabricated and coupled with temperature and pressure accessories. Zeolites were obtained from the market and clay ...
