Influence of Streamer-to-Glow Transition on NO Removal by Inductive Energy Storage Pulse Generator

Electricity is more versatile in use because it is a highly ordered form of energy that can be converted efficiently into other forms. However, the disadvantage of electricity is that it cannot be easily stored on a large scale. One of the distinctive characteristics of the electric power sector is that the amount of electricity that can be generated is relatively fixed over short periods of time, although demand for electricity fluctuates throughout the day. Almost all electrical energy used today is consumed as it is generated. This poses no hardship in conventional power plants, where the fuel consumption is varied with the load requirements. However, the photovoltaic and wind, being intermittent sources of power, cannot meet the load demand all of the time. Wherever intermittent power sources reach high levels of grid penetration, energy storage becomes one option to provide reliable energy supplies. These devices can help to make renewable energy more smooth and reliable, though the power output cannot be controlled by the grid operators. They can balance micro grids to achieve a good match between generation and load demand, which can further regulate the voltage and frequency. Also, it can significantly improve the load availability, a key requirement for any power system. The energy storage, therefore, is a desired feature to incorporate with renewable power systems, particularly in stand alone power plants. The purpose of this book is twofold. At first, for the interested researcher it shows the importance of different Energy Storage devices, but secondly, and more importantly, it forms a first attempt at dissemination of knowledge to the wider non-expert community who may wish to consider Energy Storage device for specific application. Thus this book will be helpful to provide an indication of the tools necessary for an assessment to be made Energy Storage device more powerful The experimental study on NO removal in a pulse corona discharge reactor was carried out to clarify the influence of the streamer-to-glow transition on NO removal. The inductive energy storage pulsed power generator was employed with a fast recovery diode as a semiconductor opening switch. The pulsed power generator supplied a 30 kV pulse with 300 pps repetition rate. The energy efficiency obtained for NO removal was 25 g/kWh at 30% removal. However, the energy efficiency decreased to 5 g/kWh with an increase in capacitance of the primary capacitor from several hundred pF to several nF. This decrease was caused by the streamer-to-glow transition. The efficiency was affected by oxygen concentration in the gas mixture. The efficiency was successfully improved from 5 to 20 g/kWh in the case of several nF-capacitors by changing the connection of the diode and the inductor in the pulsed power circuit Impresum_Advances_in_Speech_Recognition......Page 1 01_Santiago......Page 11 02_Suvire......Page 29 03_Siostrzonek......Page 47 04_Carbone......Page 79 05_Sheikh......Page 97 06_Takaki......Page 113 07_Lee......Page 133
