Boiler Effects On Steam Turbine Response


Exhaust Gas Boiler System For Steam TurbinesCarryover of boiler water in steam generating systems can cause a range of significant problems affecting the operation and efficiency of the system. The main adverse effect is a build-up of deposits in parts of the system such as turbines, heat exchangers, superheaters and valves.Portable Boiler Rental Info - Find Your Answer in Seconds14/2/2014 · In high pressure boilers, any chemical contaminants present in the steam can quickly build upvin the boiler drum and can be carried over in the steam to the turbine.

Steam boilers are closed vessels that contain water and will be heated so that certain pressures and temperatures can rotate the steam turbine. Because the heating process can be used to rotate the turbine requires a considerable time for 100MW, so

Adjusting the amount of water that is sprayed into the steam header after the steam has passed through the super heater controls the steam temperature. The control is difficult because there is a time delay between the addition of the spray and when the steam temperature is measured. The gain, delay, and time constant of the system response also change significantly with the MW load on the steam turbine due to changes in steam flow rates. Some boilers are equipped with burner tilt and this also directly affects steam temperature …boiler effects on steam turbine responseTurbine deposits can accumulate in a very short time when steam purity is poor.

Boiler Response to Sudden Steam Demand Steam boilers seem to operate efficiently with good steam quality when subjected to a steady steam demand at a rate matching the output of a boiler. Consequently, when a steam system valve opens quickly, a rapid steam load demand occurs, and the boiler will depressurize.
