aurutõke

Aurutõke is a term used in Estonian technical language to denote a barrier or obstruction in a steam system. In practical terms, an aurutõke refers to devices or structures designed to regulate, limit, or block the flow of steam within pipelines, boilers, or process equipment. The concept can cover both passive barriers such as baffles inside equipment, and active devices like dampers or valves that adjust steam passage.

Etymology: The word combines aur- from Estonian aur meaning steam, with tõke meaning obstruction or barrier, forming a compound common in technical vocabulary for components related to steam handling.

Function and operation: An aurutõke can serve several purposes, including reducing pressure surges, improving liquid separation from steam, preventing reverse flow, and protecting downstream equipment from excessive steam velocity. In boiler systems during startup, shutdown, or load changes, a controlled obstruction helps stabilize the flow and maintain safe operating conditions.

Applications: Found in power generation plants, refineries, chemical plants, and other facilities that rely on steam as a heat or motive medium. Depending on design, aurutõke may be fixed or adjustable, and may require periodic maintenance to avoid wear or blockage.
