Waste heat recovery from flue gas based on water vapor condensation is an important issue as the waste heat recovery significantly increases the efficiency of the thermal power units. General principles for designing of this type of heat exchangers are known rather well; however, investigations of the local characteristics necessary for the optimization of those heat exchangers are very limited. Investigations of water vapor condensation from biofuel flue gas in the model of a vertical condensing heat exchanger were performed without and with water injection into a calorimetric tube. During the base-case investigations, no water was injected into the calorimetric tube. The results showed that the humidity and the temperature of inlet flue gas have a significant effect on the local and average heat transfer. For some regimes, the initial part of the condensing heat exchanger was not effective in terms of heat transfer because there the flue gas was cooled by convection until its temperature reached the dew point temperature. The results also showed that, at higher Reynolds numbers, there was an increase in the length of the convection prevailing region. After that region, a sudden increase was observed in heat transfer due to water vapor condensation.

Abstract Corrosion rate data are presented for low carbon steel in (1) a combination of sulfur dioxide, water vapor and air, and (2) aqueous solutions of sulfurous acid in the absence of air, at ordinary temperature. Information as to the nature of the corrosion products is presented and it is shown that this depends on the place in which the corrosion takes place to an important extent.

By Products

The potential of using the waste from simultaneous NOx and SO2 purification bio-trickling process to leach copper ore and to make fertilizer was investigated. It was found there were two main exhausted by-products in the purification process: the acidic liquid in desulfurization tower and the alkalescent liquid in denitrogenation tower. Through operation of leaching the oxide ore sample containing 2.58% copper by the acidic liquid, the effective grade of the metal to be extracted reached 28.37% by weight. With adding proportional dose of ammonia into the alkalescent liquid or the acidic liquid and going through evaporation and concentration, crystal products of ammonium sulfate and ammonium nitrate were generated, which can be used in fertilizer manufacturing.
