Mercury emissions from a coal-fired power plant in Japan

2014-11-10 · The distribution of Hg species as a function of the temperature are shown in Fig. 3a ? c for the combustion of Coal-1, Coal-2 and Coal-3, respectively. The results indicate for the three coals: 1. the temperature dependency of the distribution of Hg species; 2. the major gaseous products in combustion ?ue gas are elemental Hg and HgCl2 ; and 3. no condensed Hg species are predicted above 100?C.

Reading: Coal | Geology

Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the thirteent century)is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure.

Horizontal Gas Fired Hot Water 10t Boiler Water Wall

As the water wall tubes form a lining along the whole boiler, they are submitted to a temperature gradient of 300 °C to 500 °C between the bottom section of the boiler and its top. To facilitate fitting, the panels in the boiler should preferably be made of steel grades that do not require any post-weld heat treatment.
