Wood pellet demand is huge both in different parts of the world and within the country. In general

The use of biomass fuel is getting pushed and improved lately as a result of various environmental problems and boost global climate change. Biomass fuel is classified as a renewable fuel when continually strived creative foam including fuel and "carbon neutral". Wood pellets are biomass fuels more specifically of woody biomass densification treatment-treated to improve its properties such as size and uniform level of drought, as well as high density, so as to facilitate its use. This product has actually developed a few decades ago in the era of the oil crisis and now received great attention due to the reasons mentioned above.
Wood pellet demand is huge both in different parts of the world and within the country. In general there are three types of furnaces used to produce energy from wood pellets or biomass in general, namely:
There is now to be found electricity generation using biomass fuels as a whole, but the numbers are still a bit although the biomass fuel is superior because it is more stable because it is not affected by season and climate creative foam as well as wind and water. While cofiring biomass with coal has been common practice in a number of coal power plants in developed countries.
Considerations such as biomass and coal ash chemistry is different in some compounds may restrict the use of the percentage biomass cofiring with coal to. When the amount of ash is an inorganic compound that becomes a deposit in the pipes boiler producing steam in the power plant efficiency will decrease marked one of the high temperature of the flue gas. That result is still small percentage of biomass in cofiring biomass with coal is generally below 10%. Korea is one of the countries in Asia that are now declared the use of wood pellets for biomass cofiring with coal in their power plant, with a percentage of about 2%. The positive effects of the use of biomass as fuel is fly ash causes air pollution on combustion of coal will decrease significantly when cofiring biomass with coal. Comparison of ash content and ash chemistry between coal and biomass as the table below:
Biomass, especially woody biomass material has a low ash content than almost all the coal, but the material is rich biomass ash and alkali metal compounds and alkaline earth that cause changes to alumino-silicate ash in coal. In cofiring creative foam ratio is low, ie less than 10% based on the experience of several states the power plant problem likelihood deposit on boiler tubes is acceptable. Cofiring ratio optimization to get the best course creative foam based on ash content and chemical biomass and coal ash are used.
