Next target for coal conversion: boilers designed for gas/oil

Almost any gas/oil-fired boiler can be made to burn coal. But fuel flexibility does not come cheap and it may involve substantial derating Almost 12,000 MW of oil-fired, coal-capable, generating capacity in the US have been converted back to coal. About 10,000 more megawatts are in the process of conversion, and maybe another 12,000 are under consideration. In fact, almost two-thirds of the utility boilers that were converted to oil or gas during the 1950s and 1960s may eventually burn coal again. But here the US swing to coal almost stops. Most of these retrofits have been done on relatively old boilers in eastern states. Meanwhile, oil and gas consumption by utilities in 10 western states has remained steady or has risen. A 1980 DOE survey identified 245 utility boilers that were designed for oil and were now burning oil. Half of these units are over 400 MW and most of them are under 20 years old. If even a relatively small fraction of them were converted to coal, this would do more for energy independence than all the reconversions completed so far.
