Desulfurization of coal: the microbial solution

Pollution from coal combustion is the largest problem in the current use of coal and the biggest constraint on the increased use of coal. Sulfurous emissions from the combustion of coal are cited as the leading contributor to acid rain. No cost-effective technology exists for the pre-combustion desulfurization of coal, but biotechnology may provide a solution. Previous article in issue; Next

The production of coal mining wastes can be decreased 10% by reuse of mining wastes as underground fills, or by using the waste as fuel for power plants or for raw material to make bricks or other infrastructure materials. The proper use of mined land must be decided in terms of local physical and socio-economical conditions. In European countries more than 50% of previously mined lands are

Mr Piper said ideally, all coal ash currently being produced would be recycled and then the product within the dams would be used. More than 200 million tonnes of coal ash is dumped in unlined sites across NSW, of which half is stored in the Hunter and Central Coast. The waste product is growing by 3.8 million tonnes a year. The committee will hold another inquiry hearing in Sydney on October 16.

Solutions to the energy crisis: how to achieve

Our current consumption model relies almost entirely on the use of non-renewable energy sources such as oil, gas, coal and uranium. At the current rate of consumption, oil will be the first fossil fuel to run out. According to projections, there would be between 40 and 60 years of proven reserves of conventional oil. Natural gas could be exploited for another 70 years. For coal, there would be

Rising water stress risk threatens US coal plants,

22.10.2020· While some coal-fired plants use less water than others, many of the technologies that reduce water usage come with trade-offs, including increased air pollution or reduced power plant efficiency. Fossil fuel companies often push the development of carbon capture and storage technology as a climate solution, but that also generally increases costs and water requirements.

Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature (see diagram). The hot gases and heat

In the US and EU, where many coal-fired power stations are more than 30 years old, the additional cost of inducing early closure could be relatively small. Many investors, moreover, might jump at the chance of reducing their exposure to the regulatory and reputational risks associated with coal. As a result, small CCFs could quickly close a large number of coal-fired power stations.
