The resource distribution is very extensive, for easy and . It is almost no pollution to the environment, the use of green . Renewable without having to worry about energy supplies to dry . Accord with sustainable development to use the advanced . Using the method is simple and convenient, is suitable for . Application is very wide, can develop more type of industry. Direct bustion is the earliest and most simple from biological plastid contained in the biological plastid of energy method, and thus get the most mitted to the development of biomass and the research of experts and natural conditions, direct bustion under the influence of various aspects, such as lack of oxygen, heat is easy to lost), biomass energy utilization ratio is very low, the production of energy has lasted only for the use of everyday way of biomass utilization, not only results in great waste of resources, but also because of inplete bustion and spawned many harmful substances (such as dioxin), it has to do with saving, high efficiency and safety of society today is, that is direct bustion technology can39。t largescale wide range for the , we need a more scientific way to improve the direct bustion technology, to seek benefits for us, the emergence of biomass burner, it is fit for the biomass burner, using scientific and effective method, in the case of direct bustion, seeking biomass energy efficiently, safely into the energy we need method, undoubtedly bee the fate of biomass of biomass burner technology for people, but also established the is mitted to the development of the technology and the use of biomass burner predecessors determination, but also aroused our this group of junior dedicated to one of the good wishes. This article bined with thermal chemical and thermal physics knowledge, based on your mitment to the development of biomass energy and use under the research of pioneers, additional himself for some opinions of the biomass burner, for biomass burner of the most important bustion and heat transfer these two aspects, using the bined method of theoretical calculation and practical test, evaluate the rationality of the design and calculation, it will be for future research and development of biomass energy to provide certain help.
