In the process of applying the boiler, in order to ensure the thermal efficiency of the boiler operation and the safety of the boiler operation, it is necessary to regularly perform sewage treatment on the boiler. Let me briefly share the requirements for the regular sewage operation of industrial boilers.
a) Pollution should be carried out when the boiler is under fire or low load, and it should be carried out shortly and intermittently;
b) Before the sewage is discharged, the boiler water level should be adjusted to be close to the upper limit of the normal water level. When the sewage is discharged, the water level should be closely monitored to prevent the boiler from running out of water;
c) If the person operating the blowdown valve cannot directly observe the water level of the water level gauge. Contact the monitoring staff of the water level gauge to jointly discharge the sewage;
d) The sewage must be discharged every eight hours. If multiple boilers share a sewage main pipe, and there is no check valve on the sewage pipe of each industrial fire tube boiler, simultaneous sewage discharge is prohibited;
e) No other operations should be performed during sewage discharge. If other operations are necessary, the sewage discharge should be stopped first;
f) When draining, first open the slow-open valve near the boiler, and then disconnect and close the quick-open valve away from the boiler for quick drain. After the sewage discharge is completed, close the quick-open valve first, then close the slow-open valve, and then slightly open the quick-open valve, and close it after draining the accumulated water;
g) After the blowdown operation is completed, after the blowdown valve is closed, check the blowdown pipe outlet to make sure there is no leakage.
The above is the requirement for the regular blowdown operation of industrial boilers that I share for you. Of course, this is only part of it. For details, you can consult our pre-sales engineers.
