Combustion Modification (CM) is an often used technique for reducing NO{sub X}. formation from utility boilers. CM can be implemented by changing boiler operation parameters using the existing firing equipment, or through hardware modifications. Achievable potential NO{sub x} reduction levels and long term operational effects of either approach are boiler specific. Implementation of either methodology can lead to changes in boiler operating efficiency, reliability, availability, and maintenance costs. An economic analysis of alternatives must accurately reflect associated costs. Proper implementation of the selected NO{sub x} reduction technology is essential in preventing the transformation of an emission problem into an operational problem. In a joint effort by ComEd, EPRI, and Radian Corporation, a technique has been developed to facilitate the comparison of the long term cost effectiveness of each means of implementing combustion modification. The approach begins with Baseline and Exploratory Combustion Modification (ECM) testing. Baseline tests identify critical operational design parameters. ECM testing determines the flexibility of the existing furnace to accommodate operational and/or hardware changes. The resultant test data is integrated into the Radian Furnace Simulation Model (FSM). The Radian FSM is state-of-the-art three dimensional, 2 phase flow, fluid dynamic model of the boiler furnace. The model simulates furnace conditions by drawing extensively from experience and combustion data. The model computes NO{sub x} values and operational rating factors used to compare CM approaches. These factors may include emissions concentrations, staging, waterwall corrosion potential, and flue gas temperature. These calculated factors can then be used to evaluate long term effects of CM alternatives.
