The EUCG surveyed 72 separate installations of selective catalytic reduction (SCR) systems at coal-fired units totaling 41 GW of capacity to identify the systems’ major cost drivers. The results, summarized in this article, provide excellent first-order estimates and guidance for utilities considering installing the downstream emissions-control technology.
In 2002, the Bush administration launched the Clean Coal Power Initiative in the hope that it would develop the missing technology piece of the cleaner energy puzzle. Four years and two rounds later, the U.S. electric power industry is seeing the first usable clean coal technologies emerge before its eyes.
Sliding-pressure, supercritical plants are all the rage. They generally include certain design features developed for markets and operating environments outside the U.S., where new coal-fired plants have been built in recent decades. U.S. market conditions are different, and considerable capital cost savings—with negligible operating cost differences—are possible if technology options are considered for the next wave of supercritical and ultra-supercritical steam plants.
The 267-MW Pavana III power plant (Figure 1) was officially inaugurated on January 28 by Honduran President Ricardo Maduro. It was built by Helsinki-based Wärtsilä Corp. for Tegucigalpa-based independent power producer (IPP) Luz y Fuerza de San Lorenzo S.A. (Lufussa). 1. From Finland to Central America. The new 267-MW Pavana III power plant […]
