Coal use today is no longer evocative of dirty power plants with polluting black smoke billowing from their smokestacks. Many of these plants have been transformed through technology to operate more efficiently and with significantly lower emissions. Some fire coal with other waste materials and others produce both electric power and heat transmission. Cases of plant retrofits and their new performance statistics are documented by various institutions, including the Energy Information Administration (http:// www.eia.doe.gov) and the World Coal Institute (http://www.wci-coal.com). The following examples highlight clean coal use throughout the world: (more…)

Gasification is a thermo chemical process that has been exploited for more than a century for converting solid feedstocks to gaseous energy carriers. The first gasifier patent was issued in England at the end of the 18th century and producer gas from coal gasification was mainly used as lighting fuel throughout the 19th century. At the turn of the 20th century, the main use of producer gas, obtained essentially from coal, switched to electricity generation and automotive applications via internal combustion engines. The use of producer gas was gradually supplanted by the use of higher energy density liquid fuels and as a result confined to areas with expensive or unreliable supplies of petroleum fuels. (more…)

Steam is a great heat transfer medium simply because it’s easy to move inside your system. Steam heating is known to have a very high heat retention capacity. The heat capacity of steam is much bigger compare than that of water. Steam systems are frequently working on very low pressure and generally below 220F. (more…)

Steam heating is an absolutely wonderful method to heat your home. Steam heat is always driven by steam produced from water in a pot of natural gas, oil and electricity. Then it draws through pipes and radiators and heat exchangers to heat your house or residential. Boiler is used to generate steam from water. When the water boils, steam rises through pipes to radiators to heat. Then, the hot radiators play its role to warm the house. (more…)

Insulation is what keeps the heat energy of a boiler system from leaking out of the system on its way to the end users. Inspect the condition of your insulation often enough to keep the insulation from becoming seriously deteriorated. This measure summarizes what insulation does, what to insulate, and how to insulate. It also gives you several methods of finding defective insulation, even if it is buried. (more…)

Nuclear power plants have many different designs and shapes. Early technology restrictions in nuclear power plants make huge plants with the capability to produce the greatest amount of power possible. But with more recent technology, nuclear plants size are smaller , making them less costly and easier to build. But despite their many technical and engineering differences, nuclear reactors come in two basic types: pressurized water reactor systems and boiling water reactor systems. (more…)

Geothermal energy is energy created by the heat of the Earth. Under the Earth’s crust lies a layer of thick, hot rock with occasional pockets of water. This water sometimes seeps up to the surface in the form of hot springs. Even where the water does not travel naturally to the Earth’s surface, it is sometimes possible to reach it by drilling. This hot water can be used as a virtually free source of renewable energy, either directly as hot water, steam, or heat or as a means of generating power. Geothermal energy as renewable energy is nonpolluting, inexpensive, and in most cases the sources is renewable. (more…)
