Solid Waste Fuel For Combustion in Energy Recovery System


Across the United States, there are two pressing problems: garbage disposal and electricity generation. Firstly, the infrastructure in place doesn’t properly dispose of or reuse municipal solid waste. In addition, power insecurity is becoming more prominent as power grids are becoming outdated. This project aims to provide an alternative solution for both issues by using a Brayton cycle based waste-to-energy incinerator. The overall system efficiency relies heavily on the feedstock used for incineration. One way efficiency can be increased is through pelletizing trash, ensuring an even burn profile, providing the correct amount of feedstock, and ensuring adequate energy production. However, knowledge of the energy level per feedstock amount is needed. This project aims to use the money that was awarded to be able to purchase and test various feedstock: polypropylene, polyethylene, and mixed-wood pellets, as well as shredded packing paper. The testing uses a calorimeter to measure the amount of energy that is stored in each feedstock material. The data gained can provide information necessary for calculating the amount of electricity per specified volume of the above-mentioned materials. The first stage of this project involved gathering energy contents of the pure substances listed above through research papers. In the next few weeks, we will be continuing with our own experimentation that examines the energy released when combusting combinations of these substances. Our goal is to gather calorimetry data for the pelletized and shredded material listed above. The data will be used to design the waste-to-energy incinerator
