Method of controlling the operation of a combustion device to provide safe and reliable operation while reducing NOx emission that includes providing a flow of fuel and diluent at a determined volume ratio to a flame in the combustion device; providing a flame stability sensor to generate a measurement of a characteristic of the flame, providing a flow measurement for each of the fuel and diluent, and controlling the determined volume ratio of fuel:diluent using the measurement from the flame stability sensor and/or flow measurements. A combustion system incorporating this method also is included.

System and method for controlling fired heater operations

The invention is directed to a method and formula for producing a fuel having reduced particulate emissions from an internal combustion engine. The fuel taught herein is characterized as having a cetane number ranging from about 45 to about 65, a Tdistillation property of less than about 370&#xb0; C., and having NR, AR, cetane number and Tdefined by the relation:=156+&#xd7;(cetane#&#x2212;49)+&#xd7;(&#x2212;14)+&#xd7;(&#x2212;25)+&#xd7;(&#x2212;315&#xb0; C.)Where

Diesel fuel formulation for reduced emissions

Tuning fuel composition delivered to a spark ignition, internal combustion engine as a function of driving cycle conditions results in improvements in one or more of fuel efficiency and combustion emissions.
