COMBINED COMBUSTION OF PULVERIZED COAL AND LIQUID FUEL IN A LOW POWER VORTEX BURNER

ABSTRACT
In this work we study the process of co-combustion of pulverized coal fuel (coal grinded up to 100 microns) and liquid (diesel) fuel in a new low power burner, where coal-air mixture is fed tangentially together with secondary air, and liquid fuel is atomized by a high velocity steam jet. Temperature profiles and composition of intermediate combustion products along the vertical axis of the burner have been studied. The heat release (power) and the gas composition of final combustion products have been measured. This allowed us to demonstrate the principal possibility of combined combustion of coal dust and diesel fuel in a compact laboratory burner.
