An economizer metal temperature can increase at 30 to 50F/h (17 to 28C/h) during this period and can approach saturation temperatures. The enclosure walls of most boilers are water- or steam-cooled. The water-cooled circuits carry boiling water, and the steam-cooled circuits carry steam from the drum. from previous levels of 200 to 400F

What is the temperature of a boiler in a power plant? - Quora
During the conversion process, temperature does not increase. It is, therefore, possible to have both liquid water and steam that exist at 100 degrees Celsius. While they both would exist at the same temperature, the steam would have a lot more heat energy due to the additional 540 calories per gram of heat energy that has been absorbed.
Because a steam boiler makes heat by producing steam - by boiling water, at sea level, the temperature at the boiler will be boiling or 212 °F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level, and the steam boiler temperature will be a bit higher than 212 °F for boilers operating at slightly higher pressures, as we'll illustrate in a table below.
Apr 18, 2018 · More heat transfer takes place at super heater tube and Steam temperature increase. To decrease steam temperature, air is reduced so heat absorption at water wall increases. Heat content in the flue gas decrease and heat transfer to super heater decrease. This type of control is mostly used, where convective short heater is used. STEAM TEMPERATURE CONTROLS IN POWER PLANT BY …
Steam System Losses and Savings Through Pressure Reduction A List of Boiler and Steam System Losses It is useful to summarize the typical causes of boiler and steam system losses. Most of these losses vary with steam pressure (and temperature) and can potentially be reduced by lowering the steam pressure at the boiler.
