A HRSG (heat recovery steam generator) type boiler uses waste heat from a gas turbine to generate steam that can in turn spin a steam turbine, so, kinda. You’d just need to tightly control the temperatures and flow of heating medium (flue gasses or process heat I guess) which I’d imagine is the problem. We pronounce HRSG’s as “herzig” at my combined cycle plant. They massively improve efficiency by basically spinning two turbines for the price of one. Problem is they still rely on natural gas or diesel to operate that initial gas turbine. Coke oven boilers are also a thing but I’ve never personally worked directly with them, just learned about them. They use biproduct waste heat from making coke (component of steel) to operate boilers/make process steam/spin turbines. Im sure there are other systems too but there could always be more/better. Those are just the ones I thought of quick.
