Claim 5:
6. A method for detecting contaminants in a two-phase fluid in a tank, the method comprising:
storing a set of baseline component surface temperature measurements for a component, each component surface temperature measurement in the set of baseline component surface temperature measurements corresponding to a component operating at an input power level;
measuring a component surface temperature for a component and generating a surface temperature signal corresponding to the component surface temperature;
measuring a fluid temperature and generating a fluid temperature signal corresponding to the fluid temperature; and
determining residue is present in the fluid by performing one or more of:
calculating a difference between the component surface temperature and a component surface temperature threshold value and determining the component surface temperature exceeds the component surface temperature threshold value,
calculating a change in the component surface temperature over time and determining the change in component surface temperature over time exceeds a component surface temperature change value, and
calculating a difference between the component surface temperature and the fluid temperature and determining the difference between the component surface temperature and the fluid temperature is more than a temperature difference value; and
communicating a signal that residue is present in the two-phase fluid based on one or more of the component surface temperature exceeding the component surface temperature threshold value, the change in component surface temperature over time exceeding the surface temperature change value or the difference between the component surface temperature and the fluid temperature being more than the temperature difference value.
