The burner as claimed in claim 2, wherein the first internal annular section includes an annular first port for diverting the flow of the primary air or gas to the front of the distribution means. - 53 - 4. - The burner as claimed in claim 1, wherein the cooling fluid is water, 5. The burner as claimed in claim 1, wherein the discharge nozzle comprises: a head; a cylindrical member coupled in the rear part of said head, said cylindrical member comprising a central hole in a frusto-conical shape, with a smaller diameter in the front of the head; at least a plurality of holes formed in the periphery of said cylindrical member, said holes being formed transversely around the periphery of the cylindrical body to provide a communication between the second receiving chamber and the central hole of said discharge nozzle. 6. The burner as claimed in claim 5, wherein the plurality of holes of the cylindrical member are formed in a perpendicular manner, with respect to the cylindrical member. 7. The burner as claimed in claim 5, wherein the plurality of orifices of the cylindrical member are formed tangentially at an angle of 0 to 15 degrees, to produce a swirling effect of the first air or gas flow around the burner. the pulverized air-fuel mixture. 8. - The burner as claimed in claim 1 wherein the outlet passages of said flow distribution means are separated by an angle of about 10 ° to about 20 ° from each other. 9. - The burner as claimed in claim 1 wherein the main body comprises a conical section, said conical section being uniformly - 54 - reduced from a larger diameter to a smaller diameter in the body of said burner, said smaller diameter being connected with the flow distribution means for increasing the velocity of the first flow of air or gas and said pulverized air-fuel mixture . 10. - The burner as claimed in claim 1 wherein the main body comprises an elongated conical section, said elongated conical section being uniformly reduced from a larger diameter to a smaller diameter in the body of said burner, said smaller diameter being connected with the flow distribution means for increasing the velocity of the first air or gas flow and said pulverized air-fuel mixture. 11. - The burner as claimed in claim 1 wherein the flow distribution means are in the form of a 90 ° elbow. 12 .- The burner as claimed in claim 1 wherein the flow path in the flow distribution means changes from a vertical flow to a longitudinal flow. .13.- The burner as claimed in claim 1 wherein the second plurality of holes that are arranged in register with the second distribution chamber are in a parallel relationship with respect to the outflow of the air-fuel spray mixture. . 14. The burner as claimed in claim 1 wherein the second plurality of holes that are arranged in registration with the second distribution chamber are formed in an angular position to provide a swirling effect to the first air or gas flow and said pulverized air-fuel mixture. - 55 - 15. The burner as claimed in claim 1, wherein said burner has an operating range of between 400 to 1300 kg / hr, with a pulverized air-fuel ratio of about 1 to about 3.25. , and a transportation air speed of at least 18 m / sec. 16. The burner as claimed in claim 1, wherein the pulverized fuel produces a flame between 1900 to 2000 ° C, generating a low NOx content.
