How does the steam condenser save energy

March 14, 2023

The steam condenser is a steam generator that condenses the water vapor in the flue gas into water, recycles its latent heat of vaporization as a steam generator, and makes the thermal efficiency reach 107%. Adding a condensing heat exchanger can upgrade the traditional steam generator and turn it into a condensing steam generator. It should be said that transforming the traditional steam generator into a condensing steam generator is the main way to greatly improve the thermal efficiency of the steam generator and achieve the effective utilization of resources.

In the exhaust heat loss of the steam generator, the heat loss carried by water vapor accounts for 55% to 75% of the exhaust heat loss. , which can more effectively reduce the heat loss of the exhaust gas and improve the thermal efficiency of the steam generator.

The exhaust gas temperature of the condensing steam generator can be reduced to below 40°C to 50°C, which can condense part of the water vapor in the flue gas and recycle the latent heat of vaporization of the water vapor. In addition, recycling a certain amount of water can also remove the Harmful Substance. Thermal efficiency becomes larger due to an increase in the amount of condensation of water vapor.

The heat energy recycled by the condensing steam generator includes the latent heat of high-temperature flue gas and the latent heat of vaporization of water vapor. The latent heat of recovery treatment is not changed greatly due to the drop of flue gas temperature.

However, the latent heat of vaporization of recovered water vapor changes greatly due to the decrease in temperature. When the exhaust gas temperature is high, the latent heat of recovery process is very small. Due to the drop of exhaust gas temperature, the latent heat of recovery process increases rapidly and then stabilizes. , from the point of view of condensation, the difficulty of flue gas condensation work increases with the decrease of flue gas temperature.
