If the Large Block Moving Chain Boiler Grate has been used for a long time, regular maintenance is required to ensure its longer use. The anti-corrosion maintenance method of the furnace shutdown is determined by the length of the shutdown time. Under normal circumstances, wet maintenance can be used for no more than one month of shutdown, and dry maintenance should be adopted for more than one month.
Wet maintenance: pay attention to the best use of condensed water in the boiler water, followed by the original boiler water, and then softened water; after adding alkali, the boiler water is heated to 80-100 ℃ with a slight fire and the pressure rises to 2-3 gauge pressure After 2-3 hours of protection, make the cycle reach the alkalinity balance of the boiler water. When the pressure drops, fill up the boiler water again, resulting in a pressure of 1.54 gauge, and maintain this pressure throughout the maintenance period. Large Block Moving Chain Boiler GrateThe temperature should be tested regularly, and it should be replenished at any time when it decreases; in winter, the wet maintenance should pay attention to anti-freezing, especially the sewage channel and the economizer part; before the boiler is reused, all the alkaline water in the pot should be released, and the best dry maintenance: dry The desiccant should not directly contact the metal surface of the boiler, and can be installed in a container such as an iron plate; after placing the desiccant, the hand hole and other hole covers should be tightly closed, and the valves on the steam and water pipes must be cut off; the quicklime should be replaced in time.
If the Large Block Moving Chain Boiler Grate stops for a long time, the outer surface of the furnace metal should be coated with red dan oil or other anti-corrosion paint after the soot is completely removed. After paying attention to the above maintenance methods, the boiler accessories can achieve reasonable long-term use.
