Oil Boiler maintenance

Maintenance methods for oil-fired boilers when they are not in use for a long time: There are two types: dry method and wet method. If the boiler is shut down for more than one month, the dry maintenance method should be adopted, and the wet maintenance method can be adopted when the boiler is shut down for less than one month.

(1) Dry maintenance method: After the boiler is shut down, drain the boiler water, thoroughly remove the internal dirt, rinse it, and dry it with a low fire in the furnace (be careful not to fire), and then put a block with a diameter of 10-30 mm Install the quicklime in separate trays and place it in the drum so that the quicklime does not contact the metal. The weight of the quicklime is calculated based on the drum volume 8 kg per cubic meter. Then close all manholes and hand-hole pipe valves, every three Check once a month. If the quicklime is broken into pieces, replace it as soon as it is needed. The quicklime and the pan should be taken out when the boiler is running again.

(2) Wet maintenance method: After the boiler stops, discharge the boiler water, thoroughly remove the internal dirt, rinse it, refill the treated water to fullness, heat the boiler water to 100°C, and let the gas in the water discharge out of the furnace. Then close all the valves. Do not use the moisturizing method in cold climates to prevent the boiler water from freezing and damaging the boiler.
