Embodiment Construction

[0032] With reference to the accompanying drawings, a gas burner usable in an external combustion engine (in particular, for a Stirling engine) is generally indicated by the reference numeral 1, the gas burner by combustion of a fuel gas in general or a fuel gas in particular by an air mixture to generate heat.

[0033] The burner 1 comprises: a front wall 2 defining a front side 3 of the burner 1 and forming an exchanger passage opening 4; a rear wall 5 defining a rear side 6 of the burner 1 and forming a and a tubular side wall 8 extending between the front wall 2 and the rear wall 5 .

[0034] The burner 1 further comprises a tubular diffuser wall 9 arranged inside the side wall 8 and extending between the front wall 2 and the rear wall 5 . The diffuser wall 9 has perforations for the passage of the gas mixture from the outer side 10 of the diffuser wall 9 to the inner side 11 of the diffuser wall 9 where combustion takes place.

[0035] An annular distribution chamber 12...

Abstract

A burner (1) comprises a front wall (2) with an exchanger opening (4) for the passage of a heat exchanger (14), a rear wall (5) with a fume discharge opening (7), a tubular side wall (8), a tubular diffuser wall (9) within the side wall (8), an annular distribution chamber (12) formed between the side wall (8), a combustion chamber (13) formed within the diffuser wall (9) and suitable for the insertion of the heat exchanger (14), wherein the rear wall (5) comprises a cooling interspace in flow communication with the gas supply line of the burner.

Description

technical field [0001] The invention relates to a gas burner for an external combustion engine (external combustion engine), in particular for a Stirling engine or a Rankine cycle engine. Background technique [0002] Stirling engines are known to implement the so-called Stirling cycle by using a gas (usually air or nitrogen, or in high-performance types helium or hydrogen) as a closed cycle of the thermodynamic fluid, For converting thermal energy (in particular, thermal gradients) into work (in particular, into cyclic kinematic motion) or vice versa. When a suitable temperature difference is reached between the hot and cold spots of the Stirling cycle, a periodic pulsation is triggered which usually translates into reciprocating motion of the piston. The pulsation continues as long as the temperature differential is maintained, supplying heat to hot spots and taking heat away from cold spots. [0003] As an alternative to the Stirling engine, the Rankine engine implement...
