boiler feed water qualities for power plants

Boiler continues to operate, the temperature sensor and temperature data are collected continuously transmitted to the controller, as the heating temperature gradually rises to the combustor 53 degrees. At this time, by setting the temperature controller and the current temperature of comparison, determining the water close to the set oven temperature, thus lowering the flame and pilot burner. As the temperature is set closer to 55 ℃, the burner can be based on the actual frequency of the heat demand, precise control of the size of the flame, by gradually close, maintaining the temperature at 55 ℃. When the heat demand changes, the flame will make a corresponding change in the boiler feed water qualities for power plants only works to maintain the temperature of the state, to avoid unnecessary waste of resources.

Sootblowing heating surface is to keep clean. Due to the small thermal conductivity ash, boiler feed water qualities for power plants heating surface fouling, affect the heat transfer of the heating surface, the temperature of the endothermic working fluid drops, the exhaust gas temperature rises, thereby reducing the thermal efficiency of the boiler; severe fouling, the flue gas flow reduced cross-sectional area, the flow resistance increases, increasing the wind electrical energy consumption, reduce the load of the boiler operation, even forced shutdown; fouling since the rear smoke temperature rise, the tail affect the safe operation of heating surface. Local severe fouling, it is possible to form a "smoke corridor", the local speed increase of smoke due to the heating surface, increased wear. It should periodically heating surface boiler soot blowing.

There are many kind of horizontal steam boiler feed water qualities for power plants . if you don not know some require value then you can not calculate boiler pressure , temperature and stages (eco , eva , superheater).

Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler feed water qualities for power plants, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .
