The impact of additives upon the slagging and fouling

2020-8-1 · Yihua coal, as typical coal in the Xinjiang gasification project, was adopted in this study and termed as YHc here. Table 1 suggests that the ash is rich in alkaline oxides, covering CaO, Fe 2 O 3, MgO, K 2 O, and Na 2 O, especially in CaO (22.28%) and Na 2 O (3.56%). However, the content of acidic oxide in ash is low (e.g., 10.89% for Al 2 O 3, and 0.74% for TiO 2).

Effect of circulating ash on sulfur conversion

2016-9-1 · High-sulfur bituminous Xinzhou coal from Shanxi province (SX coal) was employed in the study. The coal sample was crushed and sieved to give a particle size range of 0.075–0.106 mm. Table 1 shows the proximate and ultimate analyses along with the sulfur contents of the SX coal. Quartz sand and circulating ash were chosen as the solid heat carriers in this study.

Occupational Exposure to Coal, Genotoxicity, and

Coal is a heterogeneous mixture containing large quantities of organic and inorganic matter, including carbon, hydrogen, oxygen, sulfur, nitrogen, and organometallic forms. The presence of mineral matter in coal may result in a number of environmental and human health problems related to its mining, preparation, and combustion. During coal mining activities, large quantities of coal dust

Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the
