I am. Unlikely. Even warm fresh water must be brought to the outside temperature because it changes the ecosystem. All the chemicals produced are made into products and all excess gas is burned in the boiler system.

Most systems are closed loop and have some sort of phase where the heated fluid transfers just it's heat to the exchanger when there is more than water involved. If it is just a gas/coal fired boiler, the recondensed steam is usually recirculated as it's more efficient this way.

An interesting study on a nearby sewage plant, has stage 3 tertiary treatment before discharged into the ocean, showed that just the warm water created quite the bio diversity along the pipe and the exit.
