A New Signal Processing Approach to Find Parameters Affecting FuelConsumption in Power Plants

In this paper, a new signalprocessing approach for finding parametersaffect fuel consumption in power plants isproposed. Boiler is a nonlinear, MIMO andtime varying system with relatively large timedelays and its efficiency changes with time.Many parameters affect boiler’s efficiency ina power plant. Using historical process data ofMashhad power plant, the most probableparameters involve boiler efficiency arediscussed. In this case, Studies show thatair/fuel ratio and input gas pressure are themost important parameters can changeefficiency. An increase in the air/fuel ratiowill enhance thermal efficiency. In addition,because of incorrect air/fuel regulation table,the gas pressure affects air/fuel ratio andboiler efficiency.
