Ammonia dosing in condensate water
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
Coal Firing Nozzles
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
Boiler drum level Control
Boiler drum level control in large size boilerBoiler drum level control is a critical aspect of maintaining the safety and efficiency of large size boilers. A boiler drum is a vessel that stores water and steam in a closed system. The drum level must be carefully monitored and controlled toRead More
Understanding Steam Turbine Governing
Steam turbines are widely used in power generation, and they play a crucial role in converting the energy of steam into mechanical energy that can be used to produce electricity. One important aspect of steam turbine operation is governing, which involves controlling the speed and power output of the turbine.Read More
STEAM ATTEMPERATION CONCEPTS
The attemperation water, which is 2-5% of the total steam flow, may come from the boiler feed water pump outlet, or further downstream, just before the economizer inlet. From an energy efficiency standpoint, attemperation would be more effective and require lower flows if sprayed further downstream. The risk of waterRead More
