Cogeneration device including hydrocondenser
Device for improving the production of heat by cogeneration comprising a hot source producing steam which is expanded in a turbine the exhaust of which is connected to an air condenser ( 4 ) which removes heat, and comprising at least one second auxiliary condenser ( 5 ) in the form of a water condenser, the cooling liquid of this water condenser ( 5 ) being directed to a plant or equipment (B) in which its heat is extracted and used, then the liquid is returned to the water condenser; the water condenser ( 5 ) is incorporated into the air condenser ( 4 ).
1. A device for improving the production of heat by cogeneration comprising:
a steam boiler;
a turbine receiving the steam from the steam boiler, the steam expanding within the turbine, the turbine producing an exhaust;
an air condenser receiving the exhaust from the turbine and in which the exhaust condenses into water, the air condenser being configured to exchange a latent heat of
condensation from the exhaust with a cooling gas flowed through the air condenser, and to dissipate the heated cooling gas into atmosphere external to the air condenser;
at least one hydrocondenser receiving the exhaust from the turbine and in which the exhaust condenses into water; and
a secondary cooling circuit where a coolant for the hydrocondenser is directed toward a heat exchanger in which heat from the coolant is extracted and used, then the coolant is returned to the hydrocondenser, wherein the hydrocondenser comprises a tube
bundle incorporated in a steam distribution chamber within the air condenser, the tube bundle circulating the coolant within the steam distribution chamber, and
wherein the condensed water from both the air condenser and the hydrocondenser is looped back to the steam boiler.
2. The device of claim 1 , wherein the air condenser is further configured to exchange a total latent heat of condensation from an entirety of the exhaust received from the turbine.
3. The device of claim 1 , wherein a fan is arranged under the air condenser.
4. The device of claim 1 , wherein the coolant is water.
5. The device of claim 1 , wherein a temperature level of the secondary circuit is directly subject to a steam pressure at an outlet of the turbine.
6. The device of claim 1 , wherein the turbine is configured to have a steam exhaust temperature in a vacuum at a turbine outlet of 45° C. to 60° C.
7. The device of claim 1 , wherein the heat exchanger directs heat to a market garden or horticultural green house.
