ABSTRACT:
A fossil fuel is burned substoichiometrically in the combustor (10) of a MHD power plant to produce a high temperature, fuel-rich product gas (7). The product gas is passed through a MHD channel (12) to generate electricity. A reducing agent (9), preferably natural gas or hydrocarbon, is injected into the fuel-rich product gas (7) leaving the MHD generator (14); and the resulting mixture is held at a temperature in the range of 950.degree. C. to 1500.degree. C. for about 1 second to permit the reducing agent to decompose a portion of the nitrogen oxides formed in the combustor. The fuel-rich product gas (11) then passes thru an afterburner (18) wherein combustion is completed and any excess reducing agent is consumed.
