Evaporator of a working fluid for an otec plant comprising a cover

An evaporator of a working fluid for an OTEC plant, comprising:

• an evaporator body of elongated shape, extending along a main axis between two ends, defining an inner surface, an upper part, an intermediate part and a lower part and comprising two side walls extending between the lower part and the upper part on either side of the main axis;
• a bundle of evaporators for transporting hot water and extending along the main axis;
• a sprinkling system arranged in the upper part of the evaporator body above the bundle of evaporators and able to sprinkle the working fluid in liquid state onto the bundle of evaporators, in order to transform the working fluid into a gaseous state;
• a system for evacuating the working fluid in gaseous state, arranged in the upper part of the evaporator body above the sprinkling system;
• and
• a system for guiding fluid in gaseous state to the system for evacuating;
• wherein the guide system comprises:
• a cover of elongated shape, extending along the main axis, covering the bundle of evaporators and the sprinkling system in the upper and intermediate parts of the evaporator body, and defining an outer surface, a longitudinal opening being formed in the lower part of the evaporator body between each of the sidewalls and the cover;
• and
• two partitions arranged at each end of the evaporator body and forming a sealed connection at each of these ends, between the outer surface of the cover and the inner surface of the evaporator body.
