Feb 24, 2012 · Calculation Method: The formula for calculating steam consumption during warm-up involves parameters like steam temperature, ambient temperature, and specific heat of the pipe material.
How to calculate steam requirements for flow and non-flow applications. Including warm-up, heat losses and running loads. The optimum design for a steam system will largely depend on whether the steam consumption rate has been accurately established.
The time taken to warm up any steam main should be as long as possible within acceptable limits to minimise mechanical pipework stress, optimise safety and reduce start-up loads. If 10 minutes can be taken instead of 5 minutes, the initial steam flowrate will be reduced by half.
Calculating the amount of steam in non-flow batch and continuous flow heating processes. In general steam heating is used to. change a product or fluid temperature. maintain a product or fluid temperature. A benefit with steam is the large amount of heat energy that can be transferred.
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.

The heat-up steam at the feed water vessel depends in turn on the condensate return flow from the steam consumers with the relevant condensate temperatures, make-up water demand and water losses from the boiler for surface blowdown and bottom blowdown.
