When upgrading a heating furnace to add steam, how should the size of the flow-limiting orifice plate be calculated?
Thread Content
The heating furnace suffers from severe coking, and steam needs to be added for mixing. I would like to know from those with more experience how to determine the size of the flow control orifice plate, given a pressure of 1 MPa, a temperature of 180 degrees, and a flow rate of 750 kg per hour. Please provide the calculation method

The greater the pressure difference between the furnace pressure and the steam pressure, the smaller the diameter of the flow-limiting orifice. A flow-limiting orifice plate can restrict the maximum flow rate; regulation still requires a control valve. There is a calculation formula available here: http://www.docin.com/p-235486102.html
Good noon; this time steam is being injected into the furnace tubes, with the pressure inside the tubes at around 5 kilograms
