Description

Technical Field

[0001] The present invention relates to the technical field of energy systems, and in particular to an energy system based on a bioenergy Stirling generator. Background Art

[0002] At present, my country's biomass resources are very rich. For example, a large amount of straw, three kinds of leftovers in the forest, and urban domestic garbage are produced every year. Biomass resources are a very important energy source. In today's society, due to the limitations of technology, conditions and policies, a large amount of biomass energy cannot be used in a timely and effective manner, but has become harmful. A large amount of discarded straw seriously affects the appearance of the village and causes environmental pollution. The air pollution and fire safety problems caused by direct burning in the field are even more harmful, and even affect traffic safety and the health of the people. Therefore, turning biomass harm into benefit and making rational use of resources will save a large amount of non-renewable energy for the world and create huge economic benefits. Today, the most widely used biomass resources are to achieve power generation, mainly using three types of thermal machinery: steam turbines, gas turbines and internal combustion engines. However, the existing biomass power generation energy utilization rate is low, and there is a relatively obvious waste of resources. Summary of the invention
