RENEWABLE ENERGY POWER PLANT

Enertech Systems Industries, Inc. Biomass Powerplant or Power Station


A biomass power plant most often produces steam through combustion.

A biomass power plant typically produces steam through combustion. The steam can be used for industrial processes or to produce electricity. Alternatively, the heat from combustion could be directly used in an industrial process. Another variation is a co-fired power plant fueled by coal or natural gas combined with a biomass source.

Solid-waste fuel would typically be stored in an outdoor pile in quantities adequate to fuel the power plant anywhere from 60 days to several years. Agricultural waste fuel would be stored in silos. Agricultural products such as switchgrass, hybrid poplars, or cottonwood trees would be stored in barns or storage domes on site. Depending upon the type of boiler, the fuel is either transported directly to the powerhouse via a belt conveyor, or first processed in a chipper/grinder to produce a finer texture.

Municipal solid waste is deposited into pits where cranes mix the refuse and remove any large, non-combustible items; sometimes, it is further processed to remove ferrous materials, glass, and other non-combustible materials. In a fluidized bed boiler, the fuel is suspended on high-pressure jets of air during the combustion process.

This does not only allows combustion at relatively low temperatures and higher efficiency, but it also decreases the production of nitrogen oxide, an air pollutant.

Biomass Power Plant Components

A biomass power plant includes the following major components:

  • Fuel storage area
  • Fuel conveyor system
  • Chipper or grinder
  • Boiler
  • Turbine
  • Generator
  • Condenser
  • Pollution control devices
  • Smokestack
  • Cooling system
  • Electrical substation
  • Administration building

Combustion of the fuel produces steam in the boiler that powers a turbine/generator to generate electricity. The steam is then returned to the liquid state in a condenser by circulating cooling water around the condenser tubes containing the steam. The condensed water is then recirculated to the boiler to again be heated into steam.

In countries where district heating is common, there are dedicated heat plants called heat-only boiler stations.In countries where district heating is common, there are dedicated heat plants called heat-only boiler stations. A power station (also referred to as a generating station, power plant, powerhouse or generating plant) is an industrial facility for the generation of electric power. At the center of nearly all power stations is a generator, a rotating machine that converts mechanical power into electrical power by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator varies widely. It depends chiefly on which fuels are easily available, cheap enough and on the types of technology that the power company has access to.

Due to these phenomenon, people are seeking and searching different solutions to address these kind of problems. They have their own simple ways in doing so. They are conducting researches and studies on how to eliminate or at least minimize these global problems the world is facing.

Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity, and some use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric. Central power stations produce AC power, after a brief battle of currents in the 19th century demonstrated the advantages of AC distribution.
