Biomass can be considered strategic potential, not only because it is a renewable source of energy and it is widespread, but also because its application can provide a sufficient amount of energy to reduce emissions of CO2 and other greenhouse gases, resulting in a minimum negative impact on environment. This paper presents an overview of techniques for biomass burning, as well as technical and technological characteristics of plant for the production of energy from biomass in order to promote the implementation of renewable energy sources. It also presents the option and joint combustion of biomass and fossil fuels. The decisive factor in the increased use of biomass should be its low acquisition and operating costs, but the application of modern low-emission incinerator is economically viable only for large plants, because then gets maximum effect from the problem of fuel (straw and specially planted Culture (Miscanthus Sinesis)). .
