A method of automatic combustion control in a combustion system comprising a combustion chamber, combustion means for causing the combustion of fuel in the chamber, a heat exchanger connecting with the combustion chamber, an exhaust passage connected with the heat exchanger, and fuel supply means for supplying fuel to the combustion means, such method comprising measuring the combustion temperature in the combustion chamber and producing a first quantity corresponding in magnitude with the combustion temperature, measuring the exhaust temperature in the exhaust passage and producing a second quantity corresponding in magnitude with the exhaust temperature, producing a summation of the first and second quantities and thereby producing a summation quantity, and varying the supply of air to the combustion means in such manner as to maximize the summation quantity, whereby the combustion efficiency is also maximized. A minor amount of water is mixed with the air in the form of very small water droplets, 100 microns or less in size, to increase the combustion efficiency while controlling the buildup of combustion byproduct contaminants on the internal components of the combustion system.
