fire tube boiler corrosion

Gas hot water fire tube boiler corrosion water quality standards requirements: gas hot water boiler capacity and different parameters, according to different working conditions, perennial water treatment technology and operating experience, provide for different quality requirements and quality standards hot water boiler.

Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water fire tube boiler corrosion of 2.1MW.

Boiler blowdown regularly operating precautions and standardize the process of fire tube boiler corrosion 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.

Maintenance of oil-fired fire tube boiler corrosions introduction 1, after boiler shutdown maintenance of law put to dry water furnace, the interior completely remove the dirt, rinse, drying in the furnace with a slow fire (be careful not to fire), then the diameter of 10-30 mm partial block size of quicklime installed disc, placed in the drum, without metal contact with lime, quicklime by weight, calculated to the drum 8 kilograms per cubic meter volume, and then all of the manhole, the pipe valve closed hand hole , checked every three months, such as lime ingredients like broken, i.e. the need to replace, should be re-run the boiler and the lime extraction plate 2, the discharge water boiler furnace maintenance shutdown wet method, the inside completely remove the dirt, rinse, re-injection of treated water to the full, the water was heated to 100 deg.] C oven, so that the water out of the furnace exhaust gas, and close all valves, not be used in cold climates moisture raising method, in order to avoid damage to the furnace boiler water freezes.
