Wherever you are, there will be garbage that is a problem in big cities around the world. Especially in Indonesia such as piling garbage on the streets and not to mention the conflict between the government and residents who visited the Final Disposal (TPA). In developed countries like Denmark, Switzerland, America and France. the sewage treatment process not only to manage the stench but has turned this waste into electrical energy. As in Denmark 54 percent of waste has been converted into electrical energy.
This waste processing technology into electrical energy in principle is very simple:
Rubbish is burned to produce an inch of heat (thermal conversion process)
The heat from the combustion results is used to convert air into steam with the help of a boiler
High vapor pressure to rotate turbine blades
The turbine leads to the generator with the help of the shaft
Generators generate electricity and electricity to a home or factory.
Thermal Conversion Process
The process of thermal conversion can be done through several ways, namely incineration, pyrolysis, and gasification. Incineration is essentially the process of oxidizing organic matter into inorganic materials. The process itself is a rapid oxidation reaction between organic matter and oxygen.
The waste power plant used today uses the wrong incineration process. Trash dismantled from garbage truck and fed to inserator. Inside the waste incinerator is burned. The heat generated from the results is used to convert air to high pressure. Steam from the boiler directly to the turbine. Burning residue such as dust further so as not to pollute the environment (trucks carry the rest of the burning process).
Waste treatment technology is indeed more profitable than other power plants. As an illustration: 100,000 tons of waste is proportional to 10,000 tons of coal. In addition it can also to produce energy-free fuel and can save foreign exchange
