Analysis Focus Areas Overview

Power Plant

 

NETL’s expertise in Fossil Energy allows the energy analysis team to focus on these technological, economical, and environmental areas in the development of baseline studies, life cycle analyses, analytical tools, and quality guidelines. NETL analysts use economic models to forecast the market penetration of advanced energy systems for a variety of possible futures. The associated benefits are quantified in terms of reduced cost of energy, reduced environmental impacts, and improved energy security.

 

POWER PLANTS

Power generation analyses examines technology areas in terms of potential costs, benefits, risks, uncertainties, and timeframes.

Coal Combustion Power Plants
The majority of today’s coal-fueled power generation fleet is comprised of pulverized coal (PC) combustion power plants. Within this type of power plant, coal is initially crushed or pulverized to the consistency of talcum powder. The pulverized coal is then blown into a steam boiler with fresh air, where it combusts to produce heat. This heat is used to raise steam within boiler tubes which are built into the perimeter of the boiler walls. The thermal energy of the produced steam is converted to electricity by way of a steam Rankine cycle. The types of PC plants are typically segregated by the quality of the steam, in terms of temperature and pressure, that they produce: subcritical, supercritical (SC), ultra-supercritical (USC - the state-of-the-art), and advanced ultra-supercritical (AUSC).

Coal Gasification Power Plants
Coal gasification-based power plants, such as integrated gasification combined cycle (IGCC) and integrated gasification fuel cell (IGFC) plants, rely upon gasification of coal to produce synthesis gas (syngas) which is then utilized to produce electrical power via combinations of power generation technologies. A typical IGCC plant utilizes a gas turbines in combination with a steam Rankine bottoming cycle. An IGFC plant utilizes a solid oxide fuel cell SOFC) in combination with a steam Rankine bottoming cycle.

Natural Gas Based Power Plants
Utility-scale natural gas-based power plants are typically configured as natural gas combined cycles (NGCC). Natural gas is combusted in a gas turbine, which drives a generator to produce electrical power. The gas turbine exhaust (flue gas) exits the turbine at nearly atmospheric pressure and relatively-high temperature. The heat available in the hot flue gas is used to raise steam in a heat recovery steam generator (HRSG). Flue gas leaving the HRSG is at conditions required for emission to the stack. Steam from the HRSG is used in a steam Rankine bottoming cycle for additional electrical power production.
