Coal-Fired Power Plants Must Make Many Tough Decisions

Old coal-fired power plants in Europe and the U.S. must invest in technology to meet new emission standards, but must do so with a modest investment.  New coal-fired power plants being built in Asia and certain other countries are tasked with obtaining high conversion efficiencies which are achieved with operation at high temperatures and pressures. The result is that coal-fired power plants, whether they are new or old, have difficult decisions to make.  44I Power Plant Air Quality Decisions (PPAQD) which includes information on all coal-fired power plant products and services provides power plants and their suppliers with Decision Guides to include the latest developments presented in a format so that the benefits of each option are compared.

PPAQD provides a powerful new tool both for the plant operators and suppliers.  For example, in the last three weeks there has been a specific analysis of NOx control options for a utility which is facing a $700 million investment to comply with regional haze rules.  The major options are to install SCR or to initiate a series of projects which in combination will achieve the needed NOx reduction.  The combination options include:

A:  In Furnace:

  • Catalytic burners
  • Combustion optimization systems
  • Reburn
  • SNCR

B:   Back End:

  • Catalytic filters
  • Ozone injection
  • Hydrogen peroxide
  • Catalytic baskets in the air preheater
  • In-duct SCR

These options have been reviewed in webinars with a large number of utility people in attendance to hear presentations by GE, Siemens, Emerson, Fuel Tech, FLS, AECOM and others.
