Description

Technical Field

[0001] The utility model relates to the technical field of natural gas distribution, and specifically relates to a natural gas distribution experimental device. Background Art

[0002] Natural gas is a fossil fuel mainly composed of methane, usually found underground together with petroleum resources. It is a clean energy source that produces less carbon dioxide when burned compared to coal and oil, and is therefore considered a relatively more environmentally friendly option in terms of environmental protection. In addition to methane, natural gas may also contain small amounts of ethane, propane, butane, and other hydrocarbons, as well as some non-hydrocarbon gases such as nitrogen, carbon dioxide, and hydrogen sulfide.

[0003] In the context of seeking more environmentally friendly and sustainable energy solutions, the use of a mixture of natural gas and hydrogen is an area of great concern. When a certain proportion of hydrogen is added to natural gas, the carbon emissions can be significantly reduced during the combustion process. Different proportions of components in natural gas result in different mixing ratios with hydrogen. To determine the appropriate mixing ratios of natural gas and hydrogen with different component proportions, multiple experiments are required, and thus a dedicated natural gas distribution device for experiments is needed.
