CFB boiler bed temperature's improved fuzzy control

Keeping the regular bed temperature is the key point of making the circulating fluidized bed boiler work stably. The difficult part of the CFB bed temperature control system lies in: there are many influence factors, little tunable factors, large time delay, big inertia and strong coupling between bed temperature and the main steam pressure.
