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

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

Hydrazine dosing is a common water treatment process used in power plants to remove dissolved oxygen from the feedwater and condensate water systems. Dissolved oxygen can cause corrosion in the steam and condensate systems, which can lead to leaks and reduced system efficiency. Hydrazine reacts with the dissolved oxygen toRead More

Ammonia dosing is a common method used to maintain pH in boiler water, and it is recommended for most HRSGs to maintain pH at 25 degree centigrade temperature within a range of 9.6—10.0. Ammonia is a cheaper material used to maintain pH in boiler water, and it is known toRead More

The coal nozzle in a boiler furnace can be a significant factor in the efficient operation of the boiler system. Selecting the proper nozzle is important to ensure optimal fuel combustion and prevent problems such as slagging and fouling. According to Beckett Corporation, the fuel supplied to the nozzle mustRead More
