POWER GENERATION in C#

Decoder Code 128 Code Set A in C# POWER GENERATION

The gas generated in landfills can be tapped after the completion of the landfill, and when burnt as fuel has a calorific value about half that of natural gas This is due to the fact that there is only about 60 percent combustible methane in the gas created and this has a calorific value of 37 GJ/t compared to 50 GJ/t for natural gas Generating electricity from landfill gas is clearly a better sustainable solution than merely trapping and not using it in any productive manner It is a resource that should be employed There is the added bonus for the site operators of extra generated financial revenue from the electricity sales However, all of the environmental burdens still apply The only offset is where electricity generation by nonrenewable sources can be reduced Large municipal or industrial landfills produce gas that can be tapped to generate electricity Microorganisms that live in organic materials such as food wastes, paper, or yard clippings cause these materials to decompose This produces landfill gas, typically comprises roughly of 60 percent methane and 35 percent carbon dioxide Landfill gas is collected from landfills by drilling wells into the landfills, and collecting the gases through pipes Once the landfill gas is processed, it can be combined with natural gas to fuel conventional combustion turbines or used to fuel small combustion or combined cycle turbines Landfill gas may also be used in fuel cell technologies, which use chemical reactions to create electricity, and are much more efficient than combustion turbines However, use of the gas produced by landfills may reduce the harmful environment impacts that would otherwise result from landfill operations Landfill gas electricity generation offers major air quality benefits where landfills already exist or where the decision to build the landfill has already been made Landfill gas power plants reduce methane emissions, a global climate change agent with 23 times the negative impact of carbon dioxide A landfill gas power plant burns methane that would otherwise be released into the atmosphere or burned off in a flaring process Methane is a highly potent agent of global climate change, having about 23 times the negative impact on a pound-by-pound basis as carbon dioxide Landfill gas combustion produces some carbon dioxide, but the impact of these emissions on global climate change is offset many times over by the methane emission reductions Landfill gas generators produce nitrogen oxides emissions that vary widely from one site to another, depending on the type of generator and the extent to which steps have been taken to minimize such emissions Combustion of landfill gas can also result in the release of organic compounds and trace amounts of toxic materials, including mercury and dioxins, although such releases are at levels lower than if the landfill gas is flared

There are few water impacts associated with landfill gas power plants Unlike other power plants that rely upon water for cooling, landfill gas power plants are usually very small, and therefore pollution discharges into local lakes or streams are typically quite small
