WitrynaThis means that the turndown available is limited to approximately 2:1 for a particular nozzle. To overcome this limitation, pressure jet burners are supplied with a range of interchangeable nozzles to accommodate different boiler loads. Advantages of pressure jet burners: Relatively low cost. Simple to maintain. WitrynaThe relationship between valve lift and orifice size (and therefore flowrate) is not linear but logarithmic, and is expressed mathematically in Equation 6.5.1: Example 6.5.1 The maximum flowrate through a control valve with an …
Witryna14 lip 2024 · Therefore the meter requires a turndown ratio of at least 10:1. For example: if the meter had an advertised maximum flow of 2,000,000 m³ per day then the required turndown ratio would be 20:1, hence it can read the 100,000 m³.
