1. A combustion system, comprising:
a processor; and
a memory operatively coupled to the processor and storing: a fuel infer module comprising computer readable instructions that when executed by the processor operate to:
receive measured operating parameters comprising two or more of fuel data defining fuel characteristics used in combustion within a heater of the combustion system, emissions data defining emission gasses exiting the heater, and airflow data defining ambient air being supplied to the heater and airflow rate of air within the heater;
identify one or more relationships within the measured operating parameters that result in a list of potential fuel compositions;
select one of the potential fuel compositions from the list having sufficient likelihood of resulting in the measured operating parameters as an inferred fuel composition; and
output the inferred fuel composition to a heater controller of the heater.
