Cavity formation is an important phenomenon in the underground coal gasification (UCG) process. In the early stages of cavity formation, only the combustion reaction is performed in order to stabilize the temperature field. In the present work, we study the formation of the combustion cavity and...

The feasibility of extraction of phenol rich oil from the bio-oils obtained through pyrolysis of cashew nut shells and sugarcane bagasse is studied. The extraction rate of phenol rich oil using CO2 as a supercritical fluid is discussed. Operating parameters are optimized for the maximum...

Systematic laboratory scale experiments on coal blocks can provide significant insight into the underground coal gasification (UCG) process. Our earlier work has demonstrated the various features of the early UCG cavity shape and rate of growth through lab-scale experiments on coal combustion,...

As the share of wind in power systems increases, it is important to assess the impact on the grid. This paper combines analysis of load and generation characteristics, generation adequacy and base and peak load variations to assess the future role of wind generation. A simulation of Tamil Nadu...

India has a scarcity of electric power during peak-use periods. Most Indian utilities resort to load shedding (LS) to manage the peak demand. A review of US experience with direct load control and interruptible or time-of-use (TOU) tariffs shows successful programs. Direct load control of...

A majority of the Indian population does not have access to convenient energy services (LPG, electricity). Though India has made significant progress in renewable energy, the share of modern renewables in the energy mix is marginal. This paper reviews the status and potential of different...

Battery integrated diesel generation is one of the options for decentralized power production. They are particularly suitable for loads with significant variation in the daily demand. A methodology for the optimum sizing of integrated system involving diesel generator and battery bank for an...

This paper provides results of a survey on DSM programs for the high-tension industries of Maharashtra. Technical potentials, costs, savings and the need for financial mechanism are covered. The types of programs industries prefer and needed incentives, extent of participation, agencies suitable...
