Design And Development Of A High Pressure Oxy-Methane Combustor, Jaime Cruz Gurrola
Design And Development Of A High Pressure Oxy-Methane Combustor, Jaime Cruz Gurrola
Open Access Theses & Dissertations
Most of the greenhouse gas emissions in the US comes from the electricity sector by burning fossil fuels. Environmental regulations have been implemented to reduce the amount of CO2 emitted into the atmosphere. One method to reduce the greenhouse gas emissions to the atmosphere is oxy-fuel technology. One of the biggest challenges of oxy-fuel combustion is thermal management due to the elevated temperature combustion. The main objective of this Thesis was to design and develop a steady-state high pressure combustor that uses oxygen and methane with a thermal power input of 500 kW and operation at 20 bar pressure. An …
Development Of `Lick And Stick' Passive Wireless Temperature Sensor For Harsh Environment, Hasanul Karim
Development Of `Lick And Stick' Passive Wireless Temperature Sensor For Harsh Environment, Hasanul Karim
Open Access Theses & Dissertations
Wireless passive temperature sensors have been receiving increasing attention due to the ever-growing need of higher energy efficient and precise monitoring of temperatures in high temperature energy conversion systems such as gas turbines and coal-based power plants. Unfortunately, the harsh environment such as high temperature and corrosive atmosphere present in these systems has significantly limited the reliability and increased the cost of current solutions. Therefore, this research project presents the concept and design of a low cost, passive, and wireless temperature sensor that can withstand high temperature and harsh environment. The temperature sensor was designed following the principle of metamaterials …
Impacting Testing Of High Temperature Ceramics Through The Use Of A Vitiated Heater For Hot And Cold Fire Collisions, Adrian Trejo
Impacting Testing Of High Temperature Ceramics Through The Use Of A Vitiated Heater For Hot And Cold Fire Collisions, Adrian Trejo
Open Access Theses & Dissertations
Material testing is a crucial step during the design process as particular materials serve as safety and life saving conditions. In this study, a MoSi2 is chosen as the target specimen to undergo impact under high temperatures. An impact apparatus is designed and constructed for the purpose of propelling alumina particles at high velocities. A nozzle using compressed nitrogen gas is used to fire the particle at the desired velocities. Due to the possibility of thermal shock occurring at higher temperatures, a separate nozzle utilizing vitiation heating is designed to fire the particle at equally higher temperatures to prove the …
