Definitions
- the present invention relates to a pipe in a fire tube boiler.
- boilers for generating hot water particularly small boilers for domestic use, quite frequently have a structure that is known as "fire tube", comprising a plurality of pipes designed to convey internally the products of the combustion generated by a burner before sending them to the flue, and to be struck on the outside by the water to be heated.
- fire tube comprising a plurality of pipes designed to convey internally the products of the combustion generated by a burner before sending them to the flue, and to be struck on the outside by the water to be heated.
- the aim of the present invention is to provide a pipe which is adapted to be installed in a fire tube boiler and has high characteristics of heat exchange between the products of combustion and the water to be heated.
- the reference numeral 1 generally designates the pipe according to the invention, which is designed to convey internally the products of combustion and to be struck at its outer surface by the water to be heated.
- the pipe 1 comprises a wall 2, which has a constant thickness along its entire length, and at least one and preferably two arc-like sectors 3 and 4 are associated in contact with said wall, for example by means of a mold or by rolling, and a plurality of fins such as 3a, 4a protrude from the sectors.
- Such pipe 1 ensures good heat exchange efficiency and therefore ensures a temperature of the fins that is high enough to prevent condensation of the water vapor that is present in the combustion gases conveyed by the pipe.
- Figures 3 and 4 illustrate further embodiments reflated to the shape of the fins provided in the pipe: thus, pipe 5 of Figure 3 comprises a wall 6 having a constant thickness along its entire length, which has in contact therewith three arc-like sectors 7, 8, 9, from which fins such as 7a, 8a, 9a protrude respectively; pipe 10 of Figure 4 comprises a wall 11 with constant thickness, which has in contact therewith four arc-like sectors 12, 13, 14, 15, from which fins such as 12a, 13a, 14a, 15a protrude.
