Abstract
A boiler for heating a working fluid includes a first module containing the hearth, a burner fed by said fuel gas, and an internal water circuit for wetting the hearth and creating a first level of mass and heat exchange due to vaporization without heat transfer to the working fluid; a second module including an exchanger-condenser associated with the circuit portion for circulating the working fluid and receiving the combustion gases laden with water vapor coming from the hearth of the first module and a third module including a water vapor pump providing a third level of mass and heat exchange between the combustion gases coming from the second module and the oxidizing air injected into the enclosure via an air inlet, with a device for directing the oxidizing air to the first module after it has been heated and wetted by passing through the third module.
