HVAC (heating, ventilation, and air-conditioning) systems vary depending on the complexity of room units size from single rooms to large systems, central control, which serves several areas of a building. In large, modern office buildings with heat gains from lights, people and equipment, interior spaces often require constant cooling. Rooms within the building itself (rooms with exterior walls, ceilings or roofs), it may be necessary to heat and / or cooled the weather conditions change hourly or daily outside. In buildings over one story in height, perimeter zones in the lower levels tend to be the penetration of air infiltration without so much control. (more…)

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…)

Although the focus of many policy studies of climate change is on establishing the causal links between anthropogenic systems, emissions of greenhouse gases climate change, the line of causation also runs the other way. Short-term fluctuations in climate conditions, particularly in the temperate zones on the planet, affect energy consumption. If the popular expectation that the climate will become warmer becomes a reality, we can expect winters and summers that are warmer than those of the past. (more…)

The gradual change in the energy consumption pattern of the United States from 1860 to 1990. In the mid-1800s, biomass, principally woody biomass, supplied over 90% of U.S. energy and fuel needs, after which energy biomass consumption began to decrease as fossil fuels became the preferred energy resources. For many years, a safe illuminant had been sought as a less expensive substitute for whale oils. (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…)
