A gasometer, also known as a gas holder, is a storage container or vessel used for storing and regulating the supply of gases. Gasometers were commonly used in the 19th Century for storing gases such as coal gas. Although their usage decreased industrially with the advancement of modern gas distribution systems, gasometers remain a simple and effective method of low-pressure gas storage. ![[Gasometer.mp4]] The basic design of a gasometer consists of a large cylindrical or spherical container made of steel or other materials capable of holding gas under pressure. The container is typically situated in a water-filled or liquid-sealed chamber, which allows it to move up and down as the volume of gas inside changes. This movement helps regulate the pressure and flow of gas in and out of the container. ![[PXL_20210311_023241800.jpg]] Gasometers were historically used in gasworks to store coal gas produced by heating coal in a controlled environment. They played a crucial role in supplying gas for lighting, heating, and industrial processes before the widespread adoption of natural gas and electric power. ![[Pasted image 20241015202457.png]] In modern times, gasometers are less commonly used due to the development of pipeline systems and underground storage facilities for storing and distributing gases. Smaller-scale gasometers are still used in some industries and applications where storage and regulation of gas supply are required.
