Maintenance methods of oil fired boiler in use

In addition to daily maintenance, pay more attention to the maintenance of the system during the use of oil fired boiler The following is the maintenance of oil fired boiler in use summarized in small volume, hoping to help everyone: 1 Waterproof oil contains moisture, which makes the fire unstable and even leads to "fire break" Therefore, the fuel oil shall be waterproof from transportation and storage, and the bottom of oil tank and daily oil tank shall be equipped with drainage device When the oil boiler burns, it shall be drained when the fire is unstable 2 Anti static The fuel oil is easy to generate static electricity due to friction When the fuel oil is transported or unloaded in the pipeline, it can generate static voltage above 2oov Under the action of static voltage, the oil layer will be broken down, which will lead to discharge and spark, which can ignite the oil vapor Static electricity is one of the causes of combustion and explosion of the fuel oil Therefore, the whole oil system should discharge the static electricity in time All the static electricity in the oil system Pipelines, oil tanks, equipment, containers and oil unloading stations shall be grounded Generally, the grounding resistance shall be less than 5 Ω, and shall be verified once a year 3 No matter what type of oil fired boiler oil filter and heater are used, all kinds of filters of oil fired system shall be cleaned regularly The light oil filter shall be cleaned once a month with proper solvent and compressed air Rotate the handle of heavy oil filter left or right if necessary, rotate it at a certain angle, use hands when rotating, and do not use any tools The container and filter column of heavy oil filter shall be cleaned regularly according to the quality of oil The filter column should be immersed in the whole solution instead of being disassembled The fuel heater shall be disassembled regularly, and the carbon deposit or oil scale on the inner wall of the container and the heating pipe shall be removed by the agent or tools Always pay attention to the steam outlet or steam drain pipe of the heating pipe If there is any oil stain, it is proved that the heating pipe in the heater has penetrated and leaked, it shall be handled immediately 4 Burner: generally, the following parts of the burner shall be cleaned once a month Ignition rod: use a clean soft cloth to wipe off the dust Indicator light: use a soft and clean cloth to wipe off the dust on the light receiving part of the photocell Nozzle: disassemble the nozzle and clean the oil dirt on the filter screen with kerosene Flame stabilizer: use a clean soft cloth to wipe off the dust Oil pump filter: take out the filter and clean it with kerosene Note: ① when disassembling the nozzle, use two wrenches, one to fix the nozzle, and the other to remove the nozzle by turning it left Use force to balance to prevent excessive damage to the burner ② When the ignition rod has carbon deposition, the insulation becomes poor, which makes ignition difficult At this time, the ignition rod shall be removed for cleaning When assembling the ignition rod, the pressing screw shall be applied with proper force to avoid damaging the insulating porcelain sleeve, and attention shall be paid to the original assembly position and size, otherwise the ignition cannot be started.
