Abstract
This invention pertains to a fuel saving system capable of use in connection with boilers and furnaces of various types employed in a large variety of commercial, industrial and domestic equipments. According to the invention, a plurality of tubes is located around the burner of the boiler in such a manner that air projected from the tubes arrives at the heart of the full flame. Air is projected into the tubes from a blower connected with a wind box of a separate blower which is connected with a regulatable damper and a duct. Lower tubes supply superheated air to the bottom of the flame in the combustion chamber creating a turbulent premixed flame.
Claims1
A boiler comprising:
- a boiler including an elongated, tubular combustion chamber having a front wall and a rear wall;
- a burner mounted on said front wall of said combustion chamber and disposed to direct the flame emitted therefrom, toward said rear wall of said combustion chamber;
- a first plurality of spaced-apart, air-feeding tubes, each having an inlet and outlet opening, encased in a refractory material and mounted on said front wall of said chamber and spaced about the periphery of said burner, so as to direct the air flowing from the outlet openings thereof into the heart of the flame emitted by said burner and into the center of said combustion chamber;
- a second plurality of spaced-apart, air-feeding tubes, each having an inlet and outlet opening, encased in a refractory material and mounted on said front wall of said chamber and disposed beneath said burner and said first plurality, for directing the air flowing from the outlet openings thereof into the bottom portion of the flame emitted by said burner, so as to create turbulence therein;
- a plurality of tubular refractory shields, each of which encases one of said air-feeding tubes adjacent the outlet opening thereof, and a plurality of louvered baffles, each of which covers the outlet opening of one of said air-feeding tubes, said refractory shields, louvered baffles, and refractory encasement of said tubes cooperating to superheat the air flowing through said tubes, prior to injection into said combustion chamber;
- and
- means for supplying air under pressure to said inlet openings of said tubes, said means including a blower carried by said boiler, a windbox having an end connected with said blower, a damper connected with the other end of said windbox, and a metal duct connecting said damper with said inlet openings of said tubes, and a modulator carried by said boiler and operatively connected with said damper for regulating the flow of air therethrough.
