ABSTRACT:
A magnetohydrodynamic generator (30) is fired with a clean, medium BTU combustible gas produced in an oxygen atmosphere. The combustible gas is generated in an oxygen blown coal gasifier (10) and cleaned of sulfur compounds, nitrogen compounds, and particulate matter before being delivered to the burner (32) of the MHD generator (30). An air separation plant (70) is provided to supply oxygen to both the MHD burner (32) and the coal gasifier (10). Nitrogen from the air separation plant (70) is preheated and utilized to dry the coal supplied to the gasifier (10). A vapor generator (40) is disposed downstream of the MHD generator (30) to receive and cool the hot gases exiting therefrom thereby generating steam.
