Fluidised bed heat exchanger with controlled internal circulation
The different methods used to obtain load variations on circulating fluidised bed boilers are variation of the fluidisation speed, partial recycling of the exhaust gases, and bypassing of any external heat exchanger. The first part of this research project consisted of finding a way of progressively aerating the valve so as to vary the flow of solids. The heat exchanger subsequently developed is original in that: it consists of two compartments, one of which encases a compact bundle of tubes, this design enabling internal movement to be introduced with the circulation of solids, thus promoting heat exchange; its regulator valve is non-mechanical and is integrated with the exchanger, allowing adjustment of recovery power.
