A heating system (1) has a turbine (20) for burning a fuel to provide flue gas and electrical energy. A flue gas heat exchanger (25) receives the flue gas and uses it to heat water in three of stages. An air conduit (2) receives inlet air (3) and gases from secondary inlets (5, 26) from within the system to elevate the temperature in the main conduit (2) above ambient. An evaporator (8) recovering heat from the air flow of the main conduit, and provides energy via an evaporator coil to an air source heat pump ASHP (50). A water source heat pump WSHP (60) receives a water feed at an elevated temperature from the ASHP (50), and it cools the flue gas in a third heat exchanger stage (25(c)). Hence, WSW efficiency is high and it provides product water, as do the first and second stages of the flue gas heat exchanger (25)

A method and an arrangement for recovering heat from flue gas of a boiler (10). The method comprises passing the flue gas (G) of the boiler though a flue gas cooling unit (1), cooling the flue gas (G) by transferring heat from the flue gas (G) into a circulation (3) of a flue gas cooling liquid (CL), transferring heat energy of said flue gas cooling liquid (CL) into a heat pump (2), and arranging the heat pump (2) for receiving heat energy also from a circulation arrangement (8) of a district cooling system. The heat pump (2) is coupled to a circulation arrangement (6) of a district heating system, wherein the method further comprises transferring in the heat pump (2) heat energy (H) received from said cooling liquid (CL) and from said circulation arrangement (8) of district cooling system into said circulation arrangement (6) of district heating system, for lowering the temperature of said flue gas cooling liquid (CL) and cooling fluid of said district cooling system, and raising the temperature of heating fluid of said district heating system.

The present disclosure relates to a heat pump system for transferring heat using a body of water. The heat pump system includes a water pumping system and a heating and cooling loop that directs a working fluid through a heat exchanger where heat is transferred between the working fluid and water from the body of water. The water pumping system includes an inlet line, an outlet line, and a pump. The pump moves the water from the body of water through the inlet line to the heat exchanger then through the outlet line and back to the body of water. A biocide generating device is positioned along the inlet line for providing real-time generation of biocide in the water flowing through the inlet line. A recirculation line directs water from a tap location on the inlet line positioned downstream from the biocide generating device to the water intake.

The invention provides a system for energy distribution that uses liquid carbon dioxide as a working fluid. Evaporation of the carbon dioxide provides cooling, and compression of the carbon dioxide gas back to the liquid state provides heat. The amount of heat transferred at both stages is sufficient to provide environmental heating and cooling. Waste thermal energy from a power plant, in the form of hot water, is fed into the system and used to drive the overall process. An underground thermal energy storage system is used to store energy flowing into the system that is in excess of the current demand.
