Sacrificing anode in condenser
A sacrificing anode is a device that can be installed in a condenser to protect it from corrosion. Corrosion is a common problem in condensers, as the cooling water can contain dissolved oxygen and other corrosive substances that can cause damage to the condenser tubes and other components. A sacrificingRead More
Phosphate hideout in boiler water
Phosphate hideout is a phenomenon that can occur in boilers when the levels of phosphate in the water become too high. Phosphates are commonly added to boiler water as a treatment chemical to help prevent scale buildup and corrosion. However, under certain conditions, the phosphates can become trapped in theRead More
Silica in boiler water (boiler drum)
Silica is a common impurity that can be found in boiler feedwater, and if it is not properly removed or controlled, it can cause various issues in the boiler drum. When water is heated in a boiler, it evaporates and leaves behind any impurities, such as silica, which can thenRead More
Why during purging of utility boiler air flow maintain 30 to 40 percent?
During purging of a utility boiler, the air flow is maintained at 30 to 40 percent to ensure that there is enough air in the boiler to displace any potentially hazardous gases or vapors. Purging is a process that removes any hazardous gases or vapors that may be present inRead More
Over Fired Air
Overfire air (OFA) is a technique used in utility boilers to reduce emissions of nitrogen oxides (NOx) by injecting additional air above the primary burner zone in the furnace. The additional air helps to lower the peak flame temperature and create a more uniform temperature profile, which reduces the formationRead More
