The boiler undergoes thermal shock when cold water is introduced to the hot surfaces of the boiler wall and its tubes. Hotter feedwater means a lower temperature difference and less risk of thermal shock. To maintain the designed output. The lower the boiler feedwater temperature, the more heat is required in the boiler to produce steam.

Power Boiler Feedwater and Steam - Convergence …

The purpose of a power boiler is to create steam by applying heat energy to water. The water supplied to the boiler, which is converted to steam, is called feedwater. This feedwater system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it then returns it to the power boiler steam drum.

The heat balances for the feedwater heater arrangements shown in Figs. 5.7 and 5.8 are identical. Condensate is delivered at 95°F and leaves the feedwater heater at 320°F. An HRSG equipped with either feedwater heater will produce the same amount of steam.

Feedwater enters the steam generator through a feedwater distribution ring and is mixed with about 10% of the recirculated flow as the feedwater is directed down the bundle wrapper toward the tubesheet (Teller, 2010).The feedwater is heated by its mixing with the recirculating fluid before the mixture enters the tube bundle of the axial preheater as shown in Fig. 4.8.

2015-8-20 · Boiler feedwater. Boiler ‘feedwater’ is the water supplied to the boiler. Often, steam is condensed and returned to the boiler as part of the feedwater. The water needed to supplement the returned condensate is termed ‘make-up water’. Make-up water is usually filtered and treated before use.
