Flue Gas Heat Recovery Gas to Liquid

Flue Gas Heat Recovery Gas to Liquid

Gas-to-liquid in flue gas heat recovery generally refers to the recovery and reuse of energy by transferring heat energy from the exhaust gases to a liquid (usually water or other heat transfer medium). This process involves heat exchange technology, in which heat energy from the exhaust gas is transferred to a liquid, raising the temperature of the liquid while cooling the exhaust gas itself.

Here are some common applications of gas-to-liquid in flue gas heat recovery:

Flue gas waste heat boilers: The high temperature heat energy in the exhaust gas can be transferred to the liquid via a flue gas waste heat boiler, commonly used to generate steam or hot water for heating, production purposes or other industrial processes.

Flue gas evaporative cooling system: The heat energy in the exhaust gas can be used to heat the liquid, forming an evaporative cooling system. Such systems are often used in industrial processes that require cooling and can dissipate heat.

Heat pump systems: The heat energy in the exhaust gases can be used to heat the working medium, which is then upgraded by heat pump technology to provide heat at a higher temperature.

Process water heating: Waste heat from exhaust gases can be used to heat water for industrial processes, e.g. in the pharmaceutical, chemical or manufacturing industries.

Evaporator and concentrator systems: The heat from the exhaust gases can be used to heat liquids in an evaporator to induce evaporation or in a concentrator to condense gases in the exhaust gases.

Air conditioning and refrigeration systems: The heat energy in the exhaust gases can be used to heat the refrigerant and increase the efficiency of the refrigeration system.

In these ways, gas-to-liquid applications in flue gas heat recovery can effectively recover energy, improve energy efficiency, reduce energy costs, and at the same time reduce environmental loads.
