What are the maintenance methods of oil and gas boiler?

Maintenance of oil fired and gas-fired boiler I attention shall be paid to oil fired and gas-fired boiler during operation: 1 It is not allowed to spray smoke into the furnace for positive pressure combustion, which is very easy to burn out the burner 2 If the burner vibrates violently, it shall be stopped for inspection 3 The bottom of the boiler shall be free of water so as to prevent wet corrosion of the base II The oil fired and gas-fired boiler shall be inspected once in operation for 2-3 weeks Leakage at the contact of water level gauge, valve and pipeline flange shall be repaired 3 The boiler shall be shut down for comprehensive maintenance every 36 months after operation, and the following work shall be done: 1 Remove the scale and sludge in the boiler interior and water wall, and wash them with clean water 2 Remove the smoke and dust on the fire surface 3 Check whether there is corrosion inside and outside the welded steel plate of the boiler, and repair immediately in case of serious defects If any suspicious place is found, but it does not affect the safety of production, a record shall be made in time for future reference 4 After inspection, apply boiler paint on the fire surface to prevent corrosion IV oil and gas boiler insulation shell and boiler base shall be painted at least once a year V when the boiler is not in use for a long time, shut down the boiler for more than one month First, drain the boiler water, thoroughly remove the internal dirt, wash it, dry it in the furnace with low fire, and then install the stone ash with the diameter of 10-30mm in separate plates and place it in the furnace barrel instead of contacting the quicklime with the metal Check every three months When the boiler water is fully filled, heat it to 100 ℃, let the gas in the water out of the boiler, and then close all valves In the cold place, do not use the moisture preservation method, so as to avoid the boiler water freezing damage Advantages of oil fired and gas-fired boiler: 1) boiler rate 2) simple structure 3) use simple auxiliary equipment 4) fully intelligent automatic control and equipped with multi-level protection system 5) equipped with burner (blower) and flue silencing system to reduce the noise of boiler operation 6) it shall be equipped with automatic dosing device and water treatment device 7) other monitoring and limiting devices shall be equipped to ensure the safe operation of the boiler without supervision for at least 24 hours Oil fired and gas-fired boiler is different from coal-fired boiler, it needs to use burners to spray fuel into boiler furnace, use fire chamber to burn without using grate facilities Since fuel ash is not produced after combustion of oil fired and gas-fired boilers, there is no need for slag removal facilities for oil fired and gas-fired boilers If the oil and gas injected into the furnace are mixed with air in a certain range or extinguished, it is easy to explode Therefore, the automatic combustion and control system should be used in oil fired and gas-fired boilers The oil fired and gas fired boiler has a compact structure The small boiler body and its ventilation, water supply, control and auxiliary equipment are all set on a chassis Large and medium-sized boilers can also be assembled and delivered The main pressure components and connection methods of the oil and gas boiler are described as follows: 1 The main pressure components of the fire tube boiler: shell, tube plate, furnace tank and smoke pipe; 2 The main pressure components of the water tube boiler: drum (drum), water wall, boiler tube bundle, serpentine tube and header 3 Connection mode of main pressure parts of oil fired and gas-fired boiler: mainly welding, and some parts can also be expanded.
