We are using furnace oil for heating and drying aggregates in Hot mix plants(India) and how to test the purity of Fo on site quickly?

Simple. Burn a small, measured quantity to heat a known quantity of water and measure the temperature rise of the water.
You just need a metal container to burn the oil, a beaker for the water and a thermometer. Any unburned impurities will remain in the container.
