[0002] As we all know, heating boilers need scientific maintenance when they enter the shutdown period, and the maintenance of heating boilers is divided into dry maintenance and wet maintenance. When maintaining a heating boiler using the dry maintenance method, the boiler water needs to be drained and then dried with a low fire in the furnace. Then, the blocks of quicklime with a diameter of 10mm-30mm are divided into trays and placed in the boiler drum. Do not let the quicklime come into contact with metal. The weight of quicklime is calculated at 8 kg per cubic meter of the boiler drum volume. Then all manholes and handholes are closed. Observe once every three months. If the quicklime is broken into powder, it needs to be replaced immediately. When the boiler is restarted, just take out the quicklime and the tray. The heating boiler maintenance equipment is a device for storing quicklime, which has been widely used in the field of heating filtration maintenance.
