Method for generating electricity using cow dung as fuel

Abstract

The invention discloses a method for generating electricity using cow dung as fuel. The method comprises the following steps of: burning the cow dung in a steam boiler to prepare high-pressure steam; using the high-pressure steam to drive a steam turbine to rotate; and using the steam turbine to drive an electric generator to rotate for generating electric current, wherein the cow dung needs pre-treatment before being fed to a boiler furnace, and the pre-treatment comprises the following steps of: carrying out solid-liquid separation to fresh cow dung, so that the moisture content of the cow dung is smaller than or equal to 55%, and then wet cow dung is obtained; mixing and uniformly stirring the wet cow dung with furaldehyde residue to acquire the dung residue mixture; drying the dung residue mixture to acquire the dry dung residue mixture; thermoforming the dry dung residue mixture to acquire the cow dung electricity-generating fuel. The method uses the cow dung as the fuel to produce high-temperature and high-pressure steam which drives the steam turbine to rotate, so that the steam turbine drives the electric generator to rotate and generate electricity, thus the purpose of using cow dung to replace non-renewable resources such as coal or petroleum and the like to generate electricity is achieved.

Description

technical field [0001] The invention relates to a thermal power generation method, in particular to a thermal power generation method using cow dung as fuel. Background technique [0002] With the development and progress of human society, energy shortage has become the biggest problem facing the economic and social development of various countries. As the most important energy sources such as coal and oil are non-renewable resources, their reserves are decreasing year by year. Therefore, development can be recycled. Renewable energy has become an important strategy for energy development in countries around the world today. In my country, with the rapid development of the cattle industry, a large amount of cow dung will be produced every year. Most of these cow dung can not be used rationally, which not only pollutes the environment, but also wastes resources. Because cow dung contains a lot of lignin and cellulose, dried cow dung is flammable. In the pastoral areas of Inn...

However, due to the low combustion value and high volatile content of cow dung, it is not suitable to be used as industrial fuel, especially fuel for thermal power generation.
