Refuse Derived Fuel

There are more alternative kindle sources, each of which has advantages and disadvantages, and each of which is more recyclable for some purposes than for other purposes. The following section of this paper presents a review and sound judgment of selected alternative terminate sources.

This review and assessment considers four alternative go off sources. The four alternative give notice sources are (1) avert derived raise (garbage and other float literal), (2) bio-diesel fuel (vegetable-based oil converted into a diesel fuel), (3) photovoltaic index number (solar-derived heftiness), and (4) fuel cells (hydrogen converted into electrical power).

Refuse derived fuel is nix generated through the processing of waste heartys, or garbage. Waste material is an economic source of an alternative fuel. The limitation on the refuse derived fuel concept in the United States, however, is the environmental travail on burning the material to generate electricity. The process is stiff; however, environmental protection restrictions limit its application (Johnson & Khanna, 1997).

The technologies used in refuse derived fuel production involve two contrastive combustion methods. The bubbling fluidized bed (BFB) involves placing all solid material in a stationary bed. The spread fluidized bed (CFB) involves circulating solid material through the bed

2. Regenerative fuel cells separate water into hydrogen and type O through the application of a solar-powered electrolyzer. The hydrogen and oxygen hightail it into the fuel cell, which then generates electricity, heat, and water. Recirculation of the water to the electrolyzer renews the entire process.

Oxygen flows to the fuel cell's oxygen electrode. At this point, the oxygen reacts with the water and returning electrons to sire hydroxyl radical ions. The hydroxyl ions then flow to the hydrogen electrode, where a hydrogen reaction begins. Hydrogen flows to the fuel cell's hydrogen electrode, where it reacts with the hydroxyl ions from the electrolyte.

The electrochemical reaction produces electrons (electrical power), water, and heat. The consumption of oxygen and hydrogen is comparative to the electrical power demand (Dicks & Larminie, 2000).

apiece of the four alternative fuel sources considered renders promise for the future energy supply. The conversion of waste to energy provides solutions to two problems an energy paucity and a growing waste disposal problem. Bio-diesel fuels and fuel cells hold promise for transportation energy needs. Photovoltaic power and fuel cells will generate usable power for homes, offices, stores, and factories.

A association located in Hawaii combined the refuse derived fuel concept and the bio-diesel fuel concept. The company recycles discarded vegetable oils from waste dumps and converts the materials into high quality bio-diesel fuel (Burmeier, 2000).
