Steam air heater design calculation
WebPart 1 Calculate the average steam mass flowrate during start-up. Steam pressure onto the control valve = 2.6 bar g (3.6 bar a) Critical pressure drop (CPD) will occur across the control valve during start-up, therefore the minimum steam pressure in the heating coil should be taken as 58% of upstream absolute pressure. WebSteam air heaters consist of a row of tubes in a casing or duct. The steam is passed through the tubes and any air or gas that moves over the tubes is heated. Steam heat exchangers …
