Principles of Coal Gangue Power Generation
What is coal gangue
Coal gangue refers to the mixture of coal and gangue that cannot be extracted during coal mining. The existence of coal gangue not only wastes resources, but also causes pollution to the environment. In order to solve this problem, coal gangue power generation technology has emerged.
Definition of coal gangue power generation
Coal gangue power generation is a technology that utilizes coal resources in coal gangue for power generation. The principle is to break coal gangue into particles of appropriate size, and then generate high-temperature and high-pressure steam through combustion, driving a turbine generator to generate electricity.
Coal gangue power generation steps
The process of generating electricity from coal gangue is divided into three steps: crushing, burning, and generating electricity from coal gangue. Firstly, coal gangue needs to be crushed into appropriate sized particles through a crusher. Then, the coal gangue particles are fed into the boiler for combustion, generating high-temperature and high-pressure steam. Finally, steam is fed into the turbo generator and electricity is generated by rotating the rotor of the turbo generator.
Advantages and disadvantages of coal gangue power generation
Advantages of coal gangue power generation technology
It can fully utilize coal gangue resources, reduce resource waste and environmental pollution. At the same time, the cost of coal gangue power generation is relatively low, which can provide support for local economic development.
The drawbacks of coal gangue power generation technology
Firstly, the combustion of coal gangue can generate a large amount of harmful gases such as carbon dioxide, which causes pollution to the environment. Secondly, the combustion of coal gangue also generates solid waste such as ash, which needs to be treated and disposed of.
Coal gangue power generation technology is a technology that can effectively utilize coal gangue resources, but it also requires attention to environmental protection and solid waste treatment. In the future, with the continuous development of technology, coal gangue power generation technology will become more mature and perfect, making greater contributions to the sustainable development of energy and the environment.
