A Fuzzy Control Method Combined with Optimal Feed

It is the most effective resource use practices for coal slurry to be used as fuel for fluidized bed boiler. The dry desulfurization of slurry fluidized bed boiler is a large time delay system, and the load disturbance of this system changes frequently. In order to achieve stable control of SO2 emission and meet environmental requirements, a fuzzy control technology combined with the optimal

CN106055520A - System and method for predicting

The invention discloses a system and a method for predicting the drum water level of a circulating fluidized bed (CFB) domestic garbage incineration boiler. A moderately complex drum water level dynamic characteristic mechanism model based on a differential equation form is established first from the mechanism of drum water level change characteristic based on reasonable simplifying assumption
