  • Cost Of Selective Catalytic Reduction (SCR) Application

    The NESCAUM/MARAMA report esti- mated a combined fixed and variable O&M cost of reducing NOX by 70-80% for a 330 MW dry-bottom boiler at approxi- mately $1.1 million/yr and approximately $2.8 million/yr for a similar-sized wet-bot- tom boiler. The costing methodology esti- mates the combined fixed and variable O&M costs for all boiler types to be about $1.0 to 1.7 million/yr for 85% NOX re- moval.Learn More

  • Assessing the Exergy Costs of a 332-MW Pulverized Coal

    In this paper, we analyze the exergy costs of a real large industrial boiler with the aim of improving efficiency. Specifically, the 350-MW front-fired, natural circulation, single reheat and balanced draft coal-fired boiler forms part of a 1050-MW conventional power plant located in Spain. We start with a diagram of the power plant, followed by a formulation of the exergy cost allocation Learn More
