1. A combustion analyzer system comprising:
a combustion analyzer unit having one or more electrochemical sensors and a primary controller;
a primary probe having a distal end and a condensation elimination system operably connected to the combustion analyzer unit, the condensation elimination system comprising:
a condenser having a moisture separator, the condenser operably connected to receive combustion gas within the primary probe and condense and separate any liquid from the combustion gas into condensate and to conduct the combustion gas to the electrochemical sensors via a flue gas conduit;
a return line operatively connected between the condenser and the distal end of the primary probe;
an air pump operably connected to the flue gas conduit to pressurize the condenser, the moisture separator and the flue gas conduit; and
a water pump operably connected between the condenser and the distal end of the primary probe operable to pump liquid to the distal end of the primary probe; and
one or more secondary probes operable to communicate with the combustion analyzer unit.
