Measurements made of flue gas mercury concentrations upstream and downstream of the heat exchangers showed a significant reduction in flue gas mercury concentration within the heat exchangers. A theoretical heat and mass transfer model was developed for predicting rates of heat transfer and water vapor condensation and comparisons were made with pilot scale measurements.

When dropped, elemental mercury breaks into smaller droplets which can go through small cracks or become strongly attached to certain materials. At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas.

2015-10-16 · It is clear from full-scale boiler data14 that bromine oxidizes mercury in ?ue gas at temperatures above 380 °C. It has been proposed on the basis of kinetic modeling that this represents homogeneous oxidation.16 However, homogeneous oxidation of mercury by bromine has not been observed directly at these temperatures in combustion gases.

In the 1923 plant, 20 tons of liquid mercury was heated to mercury vapor at 35 psig, and 812F. It condensed at 1.5 psia, and 485F. It generated steam in excess of 200 psig to drive steam turbine. To improve efficiency, the steam was reheated in the mercury boiler to about 700F.

Gaseous elemental and total (elemental + oxidized) mercury (Hg) in the flue gas from a coal-fired boiler was measured by a modified ultraviolet (UV) spectrometer. Challenges to Hg measurement were the spectral interferences from other flue gas components and that UV measures only elemental Hg. To el …

2014-4-17 · The mercury vapor in the combustion chamber is mixed with the flue gas and enters the convective section of the boiler. In this section, the flue gas cools down, producing hot water and steam. Due to the decreasing gas temperature, the elemental mercury is able to react with other flue gas …

2019-8-19 · MERCURY Mercury has got to be the ultimate dodgy working fluid mercury: as remarked elsewhere on this site, in the Steamwheel gallery, (where mercury is used as a weight and sealant rather than a working fluid) it is an insidious poison of a most unpleasant kind. It has a much higher boiling point than water, at 357 degC.
