The boiler produces superheated steam at 485ºC for a nominal 20 megawatts (MW) turbine/generator set. Prior to this time, the mill had relied on six 12-bar boilers to provide steam to four small turbines to drive the mill equipment, steam to multi-effect evaporators to concentrate the cane juice, and a small 3-MW turbine/generator to cover the
Read Morecome from the boiler feedwater. Boiler start-ups and shutdowns can add a tremendous amount of deposit to the boiler tube wall. The number of start-ups is a better predictor of tube deposit density than operating hours. Time-based cleanings do not consider water chemistry (good or bad) or the amount of deposits since the last cleaning. It
Read MoreNov 08, 2021 · Boiler feed applications require high pressures because of the high temperatures of the feedwater. Water changes to gas at 212 F, but boiler feedwater can range anywhere from 225 F (107 C) up to 350 F (177 C). In order to maintain feedwater in a liquid state, the pump (and the inlet piping) must maintain pressures that are higher than the water

Read MoreBoiler feedwater is treated to protect it from two basic problems: the buildup of solid deposits on the interior or water side of the tubes, and corrosion. Prevention of scaling or buildup - The need for proper feedwater treatment is obvious if you will consider the comparison of a boiler and a pot of boiling water on the stove.
