<p>The boiler (1) consists of a double-shell heating body (2) defining at least a first volume (3), in which a heat-transfer fluid circulates, and a second, internal volume, known as a combustion chamber (4), which is equipped with a burner (5) capable of rasing the temperature of said heat-transfer fluid. Moreover, the combustion chamber (4) is surmounted by a tubular exchanger (6) which is also passed through by said heat-transfer fluid. According to the invention, the boiler comprises means for increasing the heat exchange in the combustion chamber (4), which is capable of creating a large natural draught and a very high smoke column at high temperature, and moreover for increasing the heat exchange in said exchanger (6) which is capable of creating pre-established losses of head as a function of the gain in exchange in the region of the combustion chamber and of the draught necessary for good combustion. <IMAGE></p> |
