The research of deadwood energy values

Deadwood is a key indicator of forest for evaluating the biodiversity of the behavior and management. Deadwood consists of felled and standing timber, which are in different stages of its decay, its energy value depends on the particular chemical properties of its kind - the moisture content, density, in a sense it does depend on its decomposition stage. Deadwood is a highly important as a breeding and living environment for various biological species. This paper presents an energy value, density, moisture content, calorific value statistics of the deciduous trees ( such as oak, alder, aspen and birch). Biofuel is generally classified by the combustion heat release (intense heat). Best regarded wood as a biofuel are dense wood - oak, ash, birch. Biofuel can be called any organic substance, which is technically and economically worthwhile to burn when you need to get a lot of heat. It can be argued that biofuel is a renewable energy resource. In this article there are analyzed a different sources that refer to deadwood for biofuel use. A wood as a solid fuel energy value is being analyzed as well. Evidently the solid fuel characterization methods are based on the international law of the principle that is already enshrined in the provisions and principles of the standards in Lithuania. The most important biofuels are defined on the basis of elemental analysis of fuels, calorific value, moisture content, ash content and ash fusion research. Biofuels are used for energy purposes, in terms of the important information about the wood density, particle size and other handling in the supply and use of key properties. Fuel energy utilization is calculated by weight of the dry weight and calorific value of the fuel, fuel moisture content should be determined as accurately as possibleVytauto Didžiojo universitetasŽemės ūkio akademij
