## Current NOx Performance Standard - SCR

**Advantages**
- 90% reduction
- Adaptive to most boilers
**Disadvantages**
- Expensive
- NH3 storage and slip
- Parasitic load
- SO3 generation

## Alstom – Tangential Fired Technology

## B&W – Wall Fired Technology

## Praxair – Oxygen Enhanced Combustion

## Reaction Engineering InternationalRRI - Cyclone Technology

## Cost and Performance Assumptions for Advanced NOx Combustion Control Technologies 

** **

- Note: All costs in 2005$

## How good is the methodology?

***If new technologies not available –***
- Methodology projects 93 GW for SCR control versus 102 GW by IPM for compliance with Clear Skies Act

** **

## Advanced NOx Combustion Control vs. SCR for Compliance with the Clear Skies Act (preliminary)

- Note: All costs in 2005$
