coalfeeders are pulverized to finegrained particles by coal mills before outputting to the burner. To ensure complete combustion, many control operations need to be properly performed, amount of coal should meet the demand load; valves of the cold and hot air blowers (primary blowers) are adjusted to ensure suitable primary air temperature.

To increase combustion efficiency and reduce pollutant emissions, this study presents an online closedloop optimization method and its application in a boiler combustion system. To begin with, three adaptive dynamic models are established to predict NOx emission, the carbon content of fly ash (Cfh), and exhaust gas temperature (Teg), respectively. In these models, the orders of the input ...
