Why should the cheap 8t diesel boiler georgia pickling? How pickling? The main purpose is to remove pickling boiler evaporated in the boiler heating surface iron, copper dirt, impurities such as dissolved iron, but also eliminate the effect of the silica, scale and the like. The pickling process is essentially a process of etching the inner surface layer, it is divided into two kinds of circulation pickling acid and allowed to stand. 1, the circulation of boiler waterwall acid is divided into several loops, after pickling flush water. First water was heated to 40 ~ 50 ℃, then use of cyclic dosing, adding acid. I.e., inhibitor before adding, until uniform, using pickling acid pump from the lower header of a group of injection water wall, the drum after being discharged from the lower header of another set of water wall. In order to ensure good pickling effect, the acid should be greater than the flow rate of 0.3m / s. In order not to flow into the superheater acid, pickling acid level in the drum should be maintained at a lower level visible. 2, standing pickling. Acid with an acid is injected into the pump from the water wall lower header, and maintain a certain height, a puddle is discharged after 4h. And also alkali and washed with water after pickling, so that all contact with the metal surface to give an acid basified.

Boiler blowdown regularly operating precautions and standardize the process of cheap 8t diesel boiler georgia blowdown regularly handling precautions and standardize the process: a periodic sewage Note: 1 before the sewage should contact the principal value of the furnace, and get consent before proceeding turbine. 2. When the sewage water level to maintain normal after sewage, sewage check the door is closed tight. 3. When the doors open sewage should not exceed 30S, can not open two or more sewage doors to prevent damage to the water cycle. 4. The door should open the drain slowly to prevent water hammer occurs. The water valve off a small impact should occur until the water impact disappears, and then slowly open the drain door. The operation of the valve should stand side of the valve, the valve timing is prohibited. Two blowdown flow operation: 1. After receiving the task given row, PPE dressed, F bring special wrench, open the given row situ total gate. 2. once the door fully open, contact fireman DCS screen to open the corresponding electric door sewage, sewage finished, first off the secondary door, shut the door once, by-road in turn. All sewage finished, close the door once each sewage and sewage overall door. 3. sewage, should pay close attention to the water level, the water level there is any abnormal or accident, it should stop the sewage. 4. sewage 2 hours, should check whether each door door cores sewage leakage, such as sewage drain should quickly open the door again to drain the residue may be caught at the door core (boiler should contact before the main operation value). Note: The whole process should be done and sewage closely DCS operator.
