Industrial Biomass Hot Blast Stove has a long lifespan and requires regular maintenance to ensure it will last longer. 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.
1. 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 After gauge pressure, protect it for 2-3 hours to make the cycle reach equilibrium of alkalinity of boiler water. When the pressure drops, top up the water in Industrial Biomass Hot Blast Stove, resulting in a gauge pressure of 1.54, which is maintained throughout the maintenance period. This pressure and alkalinity should be tested regularly, and it should be replenished at any time when it decreases; in winter, wet maintenance should pay attention to anti-freezing, especially in the sewage channel and economizer part; before the boiler is reused, all alkaline water in the pot should be released, so be prepared Reservoir for reuse. At the same time, rinse with clean water.
2. Dry maintenance: The desiccant should not directly contact the metal surface of Industrial Biomass Hot Blast Stove, and can be installed in a container such as an iron plate; after placing the desiccant, close the hand hole and other hole covers, and the valves on the steam and water pipes. It must be cut off; quicklime becomes powder and should be replaced in time. If the furnace is shut down for a long time, after the soot is completely removed, the outer surface of the furnace metal should be coated with red dan oil or other anti-corrosion paint.
After paying attention to the above maintenance methods, the boiler can achieve reasonable long-term use. If you have any questions, please contact us.
