It depends on the calorific value of the fuel.
Most desuperheater applications reduce the temperature of steam generated by high pressure/high temperature boilers to levels required in process operations. The primary function of a desuperheater is to lower the temperature of superheated steam or other vapors. This temperature reduction is accomplished as a result of the process vapor being brought into direct contact with another liquid such as water. The injected water is then evaporated. The two main reasons for lowering the steam or vapor temperatures are: (1) to permit operation of downstream process equipment that is designed for lower temperatures, and (2) to maintain a constant temperature for processes that require precise temperature control. 1.2
In a sealed chamber with no loss of mass, five pounds of water plus sufficient heat will produce five pounds of steam. The mass of the water remains the same, regardless of its state. Freeze it, and you'd have five pounds of ice instead.
You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
Heavy weight mild steel with screwed fittings bspt. == Normally galvanized pipes are not used for steam. Mild steel with screwed or welded fittings are the norm. Pressure and temperature are very important factors to be considered in what type of materials to be used. Steam even at low pressures can be extremely dangerous. Answer In hign temperature application nomally the alloy steel pipes are used ANSWER: Mild Steel Seemless pipes, thickness dependent on the pressure rating to be used.
