Many users ignore that the steam boiler needs to discharge the waste frequently. Because the waste discharge can help prolong the boiler’s service life.let’s share som experience on waste discharging. 1.continuous blowdown:
Continuous blowdown is also called surface blowdown which means the fireman continuously discharge the boiler water of high concentration. To do it is to decrease the the saltness and the basicity and to discharge the oil and the foam of the water.
It is also called intermittent blowdown. It is an effective way to discharge the dirt and other sediment. Furthermore,the periodic blowdown can rapidly adjust the concentration of the boiler water.and the small boiler only has periodic blowdown device. The blowdown requirement：
The blowdown quality not only depends on the amount of the waste,the discharging method and the but also the discharging
frequent blowdown; this method is especially for intermittent blowdown,when using this method, short-time and frequent blowdown is more effective than one long-time one.
3.When the discharging time increase ,the volume will decrease .in this way, it will not effect the steam supply, and can also ensure boiler water quality.
balanced blowdown: it means the interval of the blowdown is equal,and the water quality is in a balanced state.
Because of the slow speed of water circulation, the waste easily sank down in which state it is more effective to conduct periodic blowdown. Blowdown plays an important role in steam boiler operation so that the boiler works smoothly
