A pressure atomizing liquid fuel burner having an improved turndown ratio is disclosed along with a method of increasing the turndown ratio in such burners. The burner includes means for adding an amount of gas to the liquid fuel prior to the injection of the fuel which causes the liquid fuel to foam such that a liquid-gas foamed mixture is injected. The relative amounts of the aeration gas and the liquid fuel are controlled such that the injection velocity is maintained relatively constant over a wide turndown ratio in the liquid fuel. The aeration gas to be added to the liquid fuel may be preheated prior to the addition of the gas to the liquid fuel.

A method for increasing the turndown ratio in a pressure atomizing liquid fuel burner comprising the steps of: combining an amount of auxiliary gas with the liquid fuel prior to the atomization thereof in a generator/preheater in a manner which produces a substantially homogeneous foam; atomizing said foam into a combustion chamber through a pressure-atomizing means; and modulating the fuel consumption of the burner in response to temperature and pressure in said generator/preheater by controlling the auxiliary gas weight fraction in said foam such that the atomization pressure to said pressure-atomizing means remains substantially constant throughout the full turndown range of said burner.
