Flue Gas Condensation for Energy Recovery. Modern incineration plants are equipped with a boiler system transforming a major part of the energy content in the flue gases into steam. The steam generates electric power in turbine generators and produces heat in turbine condensers. The heat is fed into a district heating system.

Conventional economizers preheat boiler make-up or feed water. Condensing economizers recover both latent and sensible heat from the flue gas and are able to raise boiler efficiencies to over 90%. II Applications Conventional stack economizers are more effective where a smaller volume of water needs to be heated to a higher temperature.
Condensate recovery allows you to use all of the valuable Btu within the steam system. Depending on the pressure condensate leaving a trap contains approximately 20% of the heat energy transferred at the boiler in the form of sensible heat. Condensate recovery systems help you reduce three tangible costs of producing steam: Fuel/energy costs
Published 2008. Chemistry. This project dealt with use of condensing heat exchangers to recover water vapor from flue gas at coal-fired power plants. Pilot-scale heat transfer tests were performed to determine the relationship between flue gas moisture concentration heat exchanger design and operating conditions and water vapor condensation rate. The tests also determined the extent to which the condensation processes for water and acid vapors in flue gas
Mar 03 2021 · A boiler economizer or flue gas heat recovery unit is a piece of equipment that is installed on the stack of a boiler to improve efficiency. 1-800-237-3141 Process & Production

Mar 03 2021 · Thats right a boiler economizer can heat washdown water very efficiently. Further this cold water is well below the flue gas temperatures even after a dry economizer. However heres the catch. Flue gas from a natural gas boiler running with
Sep 30 2008 · Recovery of Water from Boiler Flue Gas Using Condensing Heat Exchangers. Technical Report Levy Edward ; Bilirgen Harun ; DuPoint John. Most of the water used in a thermoelectric power plant is used for cooling and DOE has been focusing on possible techniques to reduce the amount of fresh water needed for cooling.
Flue gas condensation systems are designed in two ways: as a single-stage recuperative shell and tube heat exchanger and two-stage systems with the first stage of the cooling recuperator (dry economizer DE) and the second stage in the form of scrubber condensing water vapor and cleaning the flue gas (wet economizer WE). An example of the first type is the installation presented in Fig. 9.1.
Aug 23 2016 · Boiler fresh makeup water (typically 10 percent to 50 percent of the boiler feedwater flow rate) was used in the TMC unit to recover flue gas water vapor and heat.
More production through flue gas heat recovery. There is a lot of energy in flue gas due to the water (3060%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmets
Stack economizers commonly used to heat water are among the simplest type of waste heat recovery. Plant workers may be familiar with these common devices that recover waste heat. Boiler stack economizers use heat energy from the gas expelled in the heating process into the stack to heat boiler feed water and reduce the amount of energy ...
