Thermodynamics of Steam Homework | Physics Forums

A boiler furnace releases 10800 KJ of heat for each kg of fuel burned and produces dry saturated steam at 10000 kPa from feedwater at 190 degrees C. How many kg of steam will be produced for each kg of fuel burned if the boiler had an efficiency of 70%.

A steam generator comprises a boiler drum, a super heater, an economizer and an air preheater. The feedwater. enters the economizer at 140oC and leaves as saturated liquid. Air is preheated from a temperature of 25oC to 250oC. Steam leaves the boiler drum (evaporator) at 60 bar, 0.98 dry and leaves the super heater at 450oC.

Saturated steam - Revolvy

If saturated steam (a mixture of both gas and saturated vapor) is heated at constant pressure, its temperature will also remain constant as the vapor quality (think dryness, or percent saturated vapor) increases towards 100%, and becomes dry (i.e., no saturated liquid) saturated steam.

Dry Saturated Steam - an overview | ScienceDirect Topics

A BWR produces saturated steam at 65 bar. The steam expands to the condenser pressure of 0.06 bar through a high-pressure turbine to 5 bar, followed by an external moisture separator which produces dry steam again, then the low-pressure turbine. Both turbines have a degree of internal moisture separation.
