effect of low boiler main vapor temperature

Reheat Temperature - an overview | ScienceDirect Topics

Superheating the steam will increase the net work output and the efficiency of the cycle. It also decreases the moisture contents of the steam at the turbine exit. The temperature to which steam can be superheated is limited by metallurgical considerations (~ 620°C). Fig. 5: The effect of increasing the boiler pressure on the ideal Rankine cycle.

Mar 05, 2010 · re: effect of low main steam temperature rmw (Mechanical) 2 Mar 10 13:24 The OP doesn't seem to want to give us any additional information, but to make some basic assumptions, for power plant turbines, which typically exhaust into a vacuum condenser, with any reasonable efficiency and at reasonably cool cooling water temperatures (2-3 in. hg. BP), it would be exhausting about 14

Low Temperature Corrosion in Boiler and Its Prevention

Typically 0.3 to 0.4 % of boiler efficiency will be lost for every 10 % increase in excess air. In some cases especially when the control load is very low, in addition to burner tilt angle or gas biasing, excess air is also to be increased to achieve the Reheat steam temperature.

Dec 18, 2009 · Low Steam Pressure in Boiler. Steam pressure and temperature are the key parameters of power generation for thermal power plants and also for process application. Steam pressure and temperature decide the amount of heat available, in the form of enthalpy, to do work in turbine. A drop in both will reduce the plant heat rate in different magnitude. Many boiler operators prefer to operate the boiler

These boilers can cool the combustion gases to below 57 ° c, and when this is achieved the water vapour recondenses back into liquid water. This state change from water vapour to liquid water re-releases heat. The lower we can get these flue gas temperatures the more latent heat we re-absorb.
