Fuel Control Technology during FCB Process of W-Shape Flame Boiler Unit

Abstract:

Fuel control is the major part during the FCB control process of the unit, especially the fuel used by W-shape of flame boiler is inferior coal which has the character of low-volatile and low heating value. The switching way, procedures and speed of the fuel during the FCB process will directly determine whether the boiler can have a stable combustion after the fuel amount is greatly reduced for the unit. In this article, the strategy for quick switching of new type of fuel amount for W-shape of boiler and quick stabilization control for boiler combustion is proposed. And in this article, we also take an example of an engineering concerning foreign affairs which has successfully implemented FCB. the boiler fuel control technology which realized the function of FCB for W-type flame boiler unit is deep analyzed. It leaves a very good reference value for the test of FCB for other similar units.
