GAS INSULATED SUBSTATION

INTRODUCTION
Conventional substations requires, small installation size, protection against atmospheric pollution and moisture, noiseless operation, nonexplosive and flame resistant, reduced maintenance, minimal radio interference, but totally enclosed substations using SF6 gas as insulation that are also known as GIS is now in widespread use in the electrical power industry .
It consist of

ABSTRACT
Fuel in any engine is burnt with air. Air is a mixture of gases and it contains approximately 78% nitrogen and 21% oxygen. Some of the oxygen is used to burn the fuel during the combustion process and the rest is supposed to just pass through unreacted. But when the peak temperatures are high enough for long periods of time, the nitrogen and oxygen combine to form a class of compounds called nitrogen oxides, collectively referred to as NOx. These compounds are one of the chie ....etc

High Efficiency Miller Cycle Gas Engine
1. INTRODUCTION
The output of gas engines for cogeneration mainly ranges from 100 to 1 000 kW. The present gas engines are broadly classified in two types: lean-burn system (1) and stoichiometric air-fuel ratio combustion system, with the lower output engines using the stoichiometric Air-fuel ratio combustion system while the medium and large size engines adopting the lean-burn system. The lean-burn system generally features in high generating efficiency and low NOx emission in ad ....etc

SYNOPSIS
An alternative configuration for a regenerative gas turbine engine cycle is presented that yields higher cycle efficiencies than either simple or conventional regenerative cycles operating under the same conditions. The essence of the scheme is to preheat compressor discharge air with high temperature combustion gases before the latter are fully expanded across the turbine. The efficiency is improved because air enters the compressor at a higher temperature, and hence heat addition in the co ....etc
