Process to generate heat

摘要

The invention relates to a process to generate heat by burning a liquid fuel in an evaporator burner oven, wherein the liquid fuel is a Fischer-Tropsch derived fuel. The fuel boils for more than 90 wt % between 160 and 400° C. and has a Fischer-Tropsch product which contains more than 80 wt % of iso and normal paraffins, less than 1 wt % aromatics, less than 5 ppm sulfur and less than 1 ppm nitrogen and wherein the density of the Fischer-Tropsch derived product is between 0.65 0.8 g/cm³ and 0.8 g/cm³ at 15° C.
