Dendro Power Basics

DENDRO POWER

Factors affecting for healthy growth of Fuel wood 

Sufficient sunlight intensity for long hours



Good irrigation and sufficient wind



Favorable soil structure



Good fertility of soil or regular supply of fertilizer to match harvest



Avoid weeds and browsing of plants at tender age.



Take care of human enemies of plantations



Take care of insects, pests and parasites.

Recommendations to avoid a fuelwood shortage  Ensuring

existing wood resources are harvested and used without waste.

 Testing

and developing fuel efficient stoves, kilns, ovens, and furnaces of sizes and uses, particularly the ones which constructed and maintained at village levels where fuelwood is consumed in large quantities.

 Instituting

policies and programs that encourage the use of alternative energy sources such as biogas and solar heat.

 Control

harvesting intensity to preserve forest productivity.

MSW requirement for power gerneration

CO2 Emission due to fossil fuel

Amount of wood for power generation

Disadvantages of fuel wood 

cost of dendro thermal power is slightly higher than that of coal



If not replaced the burnt wood with new plantation CO2 emission will not reduce



Land usage because it could affect usage of land for agriculture



When the fume comes out from the power plant must be cleaned by absorbing harmful gases but this need new technology and it is a costly exercise



Ash content must be addressed separately



Transportation of wood need extra cost



Amount of wood needed to generate same amount of power from fossil fuel or coal is high



Energy content is less



Energy efficiency is low



If not imposed strict rules and regulation doors are opened to cut trees in forest for other use.
