Steam consumed and steam utilized at the application point are not the same. Typically, steam generated in a steam boilerexceeds the amount needed at the point of use. The difference in steam consumption and steam utilization is due to: 1. Steam condensation when it travels on its way to point of use mainly due to exposed surfaces. 2. Leakages (if ...
Steam consumption within the pipe system needs to be judiciously monitored and controlled. The rate of condensation of the steam in the steam piping network depends upon the type of load (i.e. warm-up load or running load). The rate of condensation of steam needs to be taken into account for sizing the steam traps, and also in finalizing the boiler...
During the plant start-up after a long time or from cold, then the steam is required to heat the system uniformly to bring the system close to the normal working temperature of the system. The ‘warm-up load’ is the steam load which is associated with the steam consumption during the start-up of the plant. This can be either from the cold shut down,...
Process plant running load is the steam load which is related to the normal (full load) continuous load of the plant. The rate of condensation of steam during the full load running a load of the plant is minimum.
Uniform and slow system warm-up can be achieved by a small by-pass valve in parallel to the main line isolation valve. The time required to warm up the pipe network decides the warm-up (bypass) valve size. This valve can be a manual or automatic type depending on the user/client. Avoid using the main valve for warm-up as it is designed for full flo...
The use of a steam flowmeter may be used to directly measure the steam usage of an operational item of plant. This may be used to monitor the results of energy saving schemes and to compare the efficiency of one item of plant with another.
Steam consumption calculations for heat exchangers. Shell and tube heat exchangers and plate heat exchangers are typical examples of flow type applications. Therefore, when determining the steam consumption for these applications, Equation 2.6.5 should be used.
1 day ago · The formula used is: \ [ \text {Steam Flow Rate (kg/h)} = \text {Steam Density} \times \text {Velocity} \times \text {Pipe Area} \times 3600 \] Example Calculation. If steam is flowing at 5 bar, 200°C, through a pipe with a diameter of 100 mm: Approximate steam density is 5.2 kg/m³. Flow velocity is calculated using pressure.
Feb 25, 2024 · The Formula for Steam Flow Calculation. The steam flow rate can be determined using a formula that takes into account key parameters such as pressure, temperature, and flow. While different industries may have specific equations tailored to their needs, a common formula is: Steam Flow Rate = Pressure × Temperature × Flow. Here,
