Promoting renewable energy in India has assumed great importance in recent years in view of high growth rate of energy consumption, high share of coal in domestic energy demand, heavy dependence on imports for meeting demands for petroleum fuels and volatility of world oil market. A number of...

Gasification is considered to be a favourable method for converting a solid fuel into a more versatile gaseous fuel. Performance of a gasifier depends on the design of the gasifier, type of fuel used and air flow rate, etc. The applications of spouted bed for a variety of processes such as...

Photovoltaic (PV) technology has recently evolved as an attractive option for rural electrification worldwide, particularly in the developing countries. However, a number of barriers need to be addressed for its widespread introduction. Capacity enhancement of institutions and individuals is...

A 1 kWp multi purpose Battery Charging Station (BCS) as a rural electrification system installed in a remote village in Vietnam provides charging facility to the batteries brought by the users and also supplies electricity to a cultural center. About forty-five families charge their batteries...

The greenhouse gas (GHG) mitigation potentials of number of selected Biomass Energy Technologies (BETs) have been assessed in Vietnam. These include Biomass Integrated Gasification Combined Cycle (BIGCC) based on wood and bagasse, direct combustion plants based on wood, co-firing power plants...

Solar food dryers are available in a range of size and design and are used for drying various food products. Testing a dryer is necessary to evaluate its absolute and comparative performance with other dryers and the test results provide relevant information for the designer as well as the user....

The rapid growth in global enrolment of students for higher education observed in recent decades is expected to continue in the early next century. However, the role of the universities and their approach to education may undergo substantial transformation in the future. The Internet is expected...

In this study, an attempt has been made to gasify coconut shell in a fluidized and a spouted bed reactor. The effects of the gasification temperature on individual gas components, their yields and heating values for both types of beds have also been studied. The fluidized bed appears slightly...

In this paper, an attempt has been made to estimate the annual emission of certain greenhouse and other gases and substances from biomass energy sources in selected countries of Asia. For this purpose, the reported values of the different emission factor for biomass combustion have been compiled...
