    • In a method of combustion designed to achieve a further reduction in harmful emissions, especially of NOx and CO, which is viable at advantageously reduced noise levels and lower cost with any burner of a type comprising a slotted or pierced diffuser of thin sheet metal in receipt of fully or partly mixed gas and air supplies, typically in appliances comprising a heat exchanger such as the boilers of central heating systems, the essential steps are: a) supplying a uniform flow of fuel-air mixture to the slots; b) discharging the mixture from a pierced surface of substantially doughnut geometry comprising a slotted peripheral area (Ap) and an essentially solid central area (Ac) of prescribed proportions; c) bringing combustion to completion in a slender lamellar flame; d) regulating the rate of aeration to a value between 0.9 and 1.4, or e) to values less than 1.6; f) effecting a recycle of post-combustion gases.

    • A combustion system includes a combustion chamber. A fan is connected to the combustion chamber. The fan has a spin velocity. A burner is adjacent the combustion chamber. The burner defines one or more flame openings. Each flame opening has a cross section. An obstacle is associated with each of the one or more flame openings. Each obstacle is within the combustion chamber. A mixture of fuel gas and air having a mixture temperature is discharged at a discharge velocity from the one or more flame openings. A flame is positioned along the burner substantially detached from the one or more openings. A flame position sensor senses the position of the flame and generates a flame position signal based on the sensed position of the flame. A control processor maintains the flame around a prefixed optimum position by controlling a characteristic variable quantity of the mixture based on the flame position signal. The characteristic variable quantity is selected from a premixture rate value of the mixture, the discharge velocity, and the mixture temperature upstream of the flame. The discharge velocity is modified by varying the cross section of the flame openings and the spin velocity of the fan.

    • The process obtains a plurality of small flames which become violet when combusting natural gas. In particular the amount of primary air induced is at least 80% of the air stoichiometrically required for combustion; the secondary air laps all sides of each singly small flame arising from the small group of slots on the burner body, in the area where each flame leaves the surface of the burner body so as to swell it making its width at least as big as its height and/or alternatively the contact surface between each flame and the secondary air is increased right from the first steps in combustion, so that each small group creates a small flame with two divergent bladed wings, similar to "butterfly wings."

    • A method and apparatus for bending tubular bodies, wherein elemental tubular sections are gradually shifted with respect to each other, without rotation, in a V-shaped bend from a central bend section. The apparatus includes two slidingly fitted supports for housing the tubular body to be bent, and a central triangular presser acting between the supports on the central tube section. The supports are gradually moved by the presser in opposite directions to define the tube sections that are actually shifted.

    • The invention relates to an apparatus for heating fluids which includes a combustion chamber (20) in which the head (21c) of the burner with the burner openings (39) for the flames is juxtaposed with a wall (21a, 21b) of the chamber itself separating this latter from the lower portion of the apparatus; in the event of flammable substances being present in the environment surrounding the apparatus, these can enter the combustion chamber only through the openings (39) and the similar slots (50) formed in the wall (21a, 21b). This enables the ignition element (25) to ignite these substances as soon as they enter the chamber (20), thus preventing the formation of unwanted explosive or flammable mixtures in the chamber (20) and thereby contributing to the safety of the apparatus.
