Emerson's SmartProcess Multi-Fuel Boiler solution
optimizes boiler operations by minimizing steam header
pressure deviations and maximizing the combustion
of less expensive fuels. The solution increases boiler
efficiency by reducing the level of combustion air
while meeting all emission constraints. SmartProcess
Multi-Fuel Boiler also helps eliminate the need for
manual operator interventions.
SmartProcess Multi-Fuel Boiler functionality includes:
Full automatic boiler control
Separate control masters for each fuel in boiler
Btu-based firing with real-time adjustment for biomass
fuel quality
Real-time optimizer
Enhanced operator interface
