O&M Cost

 

This is a standard O&M cost result screen. The spray dryer has the following variable cost components:

•Reagent: Annual cost of lime injected into the scrubber on a wet basis. This is a function of the SO2 concentration in the flue gas and the Reagent Stoichiometry.

•Solid Waste Disposal: Total cost to dispose of the collected flue gas waste solids. This does not consider by-product gypsum sold in commerce.

•Electricity: Cost of power consumption of the scrubber. This is a function of the gross plant capacity and the Spray Dryer Power Requirement performance parameter.

•Water: Cost of water for reagent sluice in the scrubber. The cost is a function of the flue gas flow rate and the Slurry Recycle Ratio performance parameter.
