Coal gasification technology, often referred to as Integrated Gasification Combined Cycle (IGCC), is the process of gasifying coal to produce electricity. The coal is gasified by burning finely-crushed coal in an environment with less than half the amount of oxygen needed to fully burn the coal. Essentially, the coal is not burned directly but undergoes a …Web
As pointed out in the Introduction, there are four aspects of the coal production-environment problem, namely (1) Water pollution, (2) Air pollution, (3) Waste, and (4) Land subsidence. We also revisit the issue of deaths and transportation in this study. 2.1 Water PollutionWeb
• In pulverized coal combustion, the ratio of coal to carrying gas is usually in the range of y = 0.5-0.6 kg/kg. • Assuming a coal density rc = 1.5 x 103 kg/m 3, and the density of the carrying gas as rg = 0.9 kg/m 3, the volume fraction of the coal can be shown to be very small, 0.036 % .Web

To investigate the effects of oxygen staging and excess oxygen on combustion performance and gaseous pollutant emission, oxy-fuel combustion experiments with Datong coal were carried out in a 0.1 MWth oxy-fuel circulating fluidized-bed combustion (CFBC) apparatus under an O2/CO2 atmosphere with a total O2 concentration of 50%. The resulting CO2 …Web
1. The excess-oxygen level at the furnace exit must be 2% minimum (and preferably 3%). 2. The fuel lines to the burners should be balanced by a "clean air" test accurate to ±2% or better. 3. The ...Web
The coal is next pulverized into a very fine powder, so that coal will undergo complete combustion during combustion process. Pulveriser is a mechanical device for the grinding of many different types of materials. For example, they are used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants.Web
The soil heavy metal pollution is even in more urgent need of attention in China. According to China's national communique of soil pollution survey in 2014, the over-standard rate of soil heavy metal was 16.1% (Ministry of Environmental Protection of China, 2014a). Cd pollution was the most serious, followed by Hg pollution (Meng et al., 2018).Web
