The Process of Converting Waste to Energy

[IvanZhidlovsky]

Generally, WTE facilities can be divided into two process types: mass burn and refuse-derived fuel (RDF). Mass burn facilities process raw waste that has not been shredded, sized, or separated before combustion, although large items such as appliances and hazardous waste materials (more

) and batteries are removed before combustion. In mass burn systems, untreated MSW is simply burned, with the heat produced converted into steam, which can then be passed through a steam turbine to generate electricity or used directly to supply heat to nearby industries or buildings.

RDF is a result of processing MSW to separate the combustible fraction from the noncombustibles, such as metals and glass. RDF is mainly composed of paper, plastic, wood, and kitchen or yard wastes, and has a higher energy content than untreated MSW. Like MSW, RDF is then burned to produce steam and/or electricity. A benefit of using RDF is that it can be shredded into uniformly sized particles or compressed into briquettes, both of which facilitate handling, transportation, and combustion. Another benefit of RDF rather than raw MSW is that fewer noncombustibles such as heavy metals are burned.


Does anyone know proper technologies that are used in the sphere?

Ivan,

While the title of this forum is "engine and fuel engineering" this is an automotive thread and if the technology you discuss is viable in any sphere, one of them is not automotive due to the copious material handling issues that do not lend themselves to automotive applications.

I suggest that you red flag this thread and ask site management to remove it after re-posting it in the Engineering Forums by Industry section under Heat: Combustion Engineering forum.

I think you will find peers lurking there who are more in tune with the sphere that you are wanting to address.
