I. Wood and woody biomass in Classifications of Biomass In classifications of biomass Woody biomass is a biomass-derived from trees. Classifications of biomass are classified into construction waste, sawmill waste and forest waste (such as twigs and fallen leaves in the mountains). Woody biomass is a renewable energy source, as new forests can be developed…
Thermochemical conversion technologies Biomass conversion technologies: Thermochemical conversion is an efficient method of converting biomass into biofuels. It includes two different categories: dry (non-aqueous) techniques and hydrothermal techniques. In a dry thermochemical biomass conversion technologies process, with increasing temperature, the biomass mainly undergoes structural destruction, degrading into condensable vapours and finally decomposing into gaseous molecules….
Biogas generation plants In Biogas generation plants a decentralized energy system, which can lead to self-sufficiency in thermal and energy needs and, at the same time, reduce environmental pollution. The main components of a modern biogas (or anaerobic digestion) plant include manure collection, anaerobic digester, effluent treatment, biogas storage and use of biogas/electricity generation equipment….
Choice of feed material of biogas digester design consideration Biogas digester design consideration: So you have a potential site for a biogas plant and, as in most cases, as a developer of a new plant, you will have at least some organic matter to use as feedstock. However, there is a decision to be made…
Hydrothermal Energy sources have common factors are water (hydro) and warmth (thermal). These geothermal reservoirs of steam occur naturally where magma comes close enough to the surface to heat spring water trapped in fractured or porous rocks, or where water circulates at great depth along faults. WHAT ARE HYDROTHERMAL ENERGY SOURCES? A geothermal resource requires…
SOURCE OF GEOTHERMAL ENERGY: Geothermal energy is heat within the earth. The word geothermal basically comes from the Greek words which are broken into 2 parts like geo means (earth) and thermal means (heat). Geothermal energy is a source of renewable energy because heat is continuously produced inside the world. Peoples are using geothermal energy…
GEO PRESSURIZED HOT DRY ROCK: Hot dry rock is an abundant source of heat available for use. A concept for extracting valuable amounts of heat from HDR originated at Los Alamos National Laboratory in 1970, and researchers at the Laboratory have received a US patent covering it History of the GEOPRESSURIZED HOT DRY ROCK Konstantin…
Design considerations of horizontal and vertical axis wind machines: In the Design considerations of horizontal and vertical axis wind machines, there are two kinds of wind turbine which produce electrical energy from the wind: they are horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). The second, and in specific straight-bladed VAWTs, have a shortened…

Wind turbines attach the power of the wind and custom it to generate electricity. Merely stated, wind turbines exert the conflicting of a fan. In its place of using power to make wind—like a fan—wind turbines usage wind to form electricity. The wind rotates the blades, which in turn turns a generator to generate electricity….
EXAMINATION OF AERODYNAMIC FORCES ACTING ON THE BLADE Aerodynamic forces acting on a blade component tending to the kind it rotates, are significant limits for a classification engineer. These are several basic kinds of blades on aero turbine may have, e.g., sails, planes and aerodynamic surfaces based on the aircraft wing cross-section for which there…

Prospects of geothermal energy in India: An eco-friendly source for the production of electricity is Biomass also holds considerable potential for India. Our estimates indicate that, with this utilization pattern of crop residues, the quantity of surplus biomass materials is about 150 million tonnes, which could generate about 16,000 MW of power. In Prospects of…
Magma geothermal energy source The conventional geothermal power generators use the steam from the world for generating electrical power. In the magma power grid, heat heats from magma around 1000 ℃ are often wont to generate strong steam for driving the turbine within the power station. We have been seeking natural high-heat sources. Perfect geothermal…
What is geothermal energy? Geothermal energy is the thermal energy generated and stored within the world. Thermal energy is the energy that determines the temperature of the substance. The heat of the crust originates from the first formation of the earth and from the decay of materials (in currently uncertain but possibly roughly equal proportions)….

Advantages and disadvantages of biogas: Worldwide interest in renewable energy sources is gaining momentum. Biogas production is continuously growing as more and more people install biogas plants to produce biogas. Biogas is ecological Biogas is a renewable source of energy. The gas generated by bio digestion is not a pollutant; it reduces greenhouse gas emissions…
