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
Importance of maintaining pH in boiler water
Maintaining the pH value of a boiler is important because it helps to prevent corrosion and scale buildup within the system. If the pH level of the boiler water is too low (acidic), it can cause corrosion of the metal surfaces in the boiler, including the tubes and pipes, whichRead More
