An ordinary boiler works like this: fuel is burned in a combustion chamber. Water runs through this combustion chamber in many small, winding pipes (a construction called a "heat exchanger"), which is how the water is heated. This works pretty well, and you can extract most of the heat gained from burning the fuel this way.
