Woody biomass waste is generated throughout California from forest management, hazardous fuel reduction, and agricultural operations. Open pile burning in the vicinity of generation is frequently the only economic disposal option. A framework is developed to quantify air emissions reductions for projects that alternatively utilize biomass waste as fuel for energy production. A demonstration pro...

Base station sites (BSSs) powered with renewable energy sources have gained the attention of cellular operators during the last few years. This is because such “green” BSSs impose significant reductions in the operational expenditures (OPEX) of telecom operators due to the possibility of on-site renewable energy harvesting. In this paper, the green BSSs power supply system parameters detected t...

This paper compares conventional and microwave hydrothermal carbonization (HTC) of human biowaste (HBW) at 160 °C, 180 °C and 200 °C as a potential technology to recover valuable carbonaceous solid fuel char and organic-rich liquor. Also discussed are the influence of HTC heating methods and temperature on HBW processing conversion into solid fuel char, i.e. yield and post-HTC management, dewat...

This paper details the development of an innovative "green" hybrid rocket propulsion system, applicable to small spacecraft. When fully developed this propulsion technology has the potential to act as a "drop in" replacement for propulsion system utilizing hazardous propellants such as hydrazine. Fuel grains are manufactured using a form of additive manufacturing known as Fused Deposition Model...

High temperature polymer fuel cells operating at 100 to 200C require simple fuel processing and produce high quality heat that can integrate well with domestic heating systems. Because the transportation of hydrogen is challenging, an alternative option is to reform natural gas on site. This article presents the development of a dynamic model and the comparison with experimental data from a hig...

Oxy-fuel combustion is one of the energy utilization technologies for CO2 capture which is ready for commercial demonstration. System steady-state simulation is an effective tool to help us understand the thermodynamic properties and adjust operation conditions of oxy-fuel combustion system. Moreover, dynamic simulation is essential for understanding the dynamic characteristics of the system, w...

The present protocol presents a laboratory technique designed to study chaparral crown fire ignition and spread. Experiments were conducted in a low velocity fire wind tunnel where two distinct layers of fuel were constructed to represent surface and crown fuels in chaparral. Chamise, a common chaparral shrub, comprised the live crown layer. The dead fuel surface layer was constructed with exce...

In recent days, current research is going in alternative fuels due to increase in global warming and pollution in all over the world and also very stringent emission norms. In this way, the study on spray progress plays an important role in improving complete combustion and emission of fuel, because it is directly affects the air-fuel mixture formation. The macroscopic spray characteristics of ...

Fuel cell power plants with an integrated fuel processing system for hydrogen generation are an attractive option for stationary, distributed power generation. We consider a PEM fuel cell power plant with CPO based fuel processor for generating hydrogen from natural gas. During load transients, the temperatures at various points of the fuel processor need to controlled tightly so that the catal...
