Einrichtung zum Verbrennen von flüssigen Brennstoffen hoher Viskosität

摘要

A furnace for burning highly viscous combustibles in which the materials are sprayed into a preheated combustion chamber. The spraying device has a fuel-spraying nozzle which is associated with an annular discharge nozzle for spraying medium such as compressed gas, steam, etc. The spraying medium combines with the fuel exteriorly of the nozzle and is combined with primary air combustion air. A device is provided for spraying secondary air in the direction for accelerating the sprayed stream of fuel to sweep the refractory wall within the furnace for effecting complete combustion of any unburned particles deposited therein. The exhaust gases are discharged through a flue into a remote heat exchanger for recovering the heat of combustion prior to passage through the stack.
