A modern clean burn stove has two combustion areas and two air intakes. The first combustion is a small high temperature zone, where syngas and small particle carbon is created, these are mixed with fresh air and burned in the second combustion zone. Temperatures in the second zone can be very high indeed. My stove had a water jacket surrounding the second zone, it was very efficient.
The ultimate limit on how much heat you can extract is the flue temperature, it has to be hot enough to cause a good draw up the chimney.
My ideal stove would have an air intake from outside, to stop it pulling warm room air up the chimney, a secondary burn zone in a water jacket, and a high thermal mass to even out the temperature spikes in the house.
