【文章內(nèi)容簡介】 can be found easily in any place and any time. In fact, biomass will not be useful for producing electrical power energy unless converted into another form. Consequently , if any pany wants to use biomass as a source of energy instead of oil or gas, it will need to collect the biomass ( plants, wood and so on ) and burn it in special places, then the heat of this burning can be used in a steam turbine to generate electricity. In the same way, power plants can use biomass in a different process which called Gasification. In this case, biomass is going to be heated at very high temperature degrees to produce flammable gases which can be used to rotate the turbine and produce electricity. According to the California Energy Commission web site, California produces about 60 million tons of biomass every year, which means around 2021 megawatt of electrical power. In fact, this power is enough to market and could supply about two million homes. Although biomass energy has been used many years ago, some countries still use it as a fuel in electrical power generation until now. In contrast, some countries stopped using it because of its environmental impacts. It has been said that biomass has been contributing to the environmental pollution. However, the benefits of this energy encouraged some societies to use it, for instance, BEG (The Biomass Energy Group) has concluded that a biomass industry in Scotland has the potential to supply as much as 450 MW of electricity from the wood fuel resource while employing over 2021 people and stimulating other sectors of the Scottish economy. In addition ， EIA (The Energy Information Administration) estimation of biomass resources shows that there are 590 million wet tons (equivalent to 413 million dry tons) of biomass available in the United States on an annual fact, biomass can be used in power plants using different methods and each method has its own efficiency and productivity. Electrical Power Generation from waste Generating electricity in power plants using fossil fuel is the most popular method in the world. However, using biomass to generate electricity can be efficient with some regulations and limitation. There are four main types of biomass power systems: directfired, cofired, gasification, and modular systems. Most of the power plants which use biomass are directfired systems which use the same technique of Fahad
