In order to ensure the normal operation and operation safety of gas-fired boiler, we must correctly use fuel oil, heater, filter, fuel nozzle and other relevant accessories to avoid flameout of gas-fired boiler.

燃料添加到燃氣鍋爐中需要定期脫水。脫水和回收的燃料油應先淨化後再送入油缸。同時，必須明確油位和油溫的上限和下限，以確保能夠達到正常的燃油供應效果。此外，應定期清潔鋼底底部的沉澱物，以免堵塞。

The fuel added to the gas-fired boiler requires regular dehydration. The dehydrated and recovered fuel oil shall be purified before being sent to the oil cylinder. At the same time, the upper and lower limits of oil level and oil temperature must be clear to ensure normal fuel supply. In addition, the sediment at the bottom of the steel bottom shall be cleaned regularly to avoid blockage.

加強燃氣鍋爐燃料油的使用管理，掌握燃油加注油種類。如果油品有差異，則需要進行混對測試。如果發生沉澱應將其分缸儲存，以避免由於混合存儲結塊而導致燃氣鍋爐堵塞。

Strengthen the use and management of fuel oil for gas-fired boilers and master the types of fuel oil. If the oil products are different, the mixing test is required. If precipitation occurs, it shall be stored in cylinders to avoid blocking of gas-fired boiler due to mixing and storage agglomeration.

燃氣鍋爐中配置的加熱器也應定期檢查，如果發生泄漏，應及時進行維護。使用蒸汽和空氣霧化油噴嘴時，應在調壓工作中防止油壓低於蒸汽和空氣壓力，從而可以有效地防止燃油無法進入噴油嘴的情況。

The heater equipped in the gas-fired boiler shall also be inspected regularly. In case of leakage, it shall be maintained in time. When using steam and air atomizing oil nozzle, prevent the oil pressure from being lower than the steam and air pressure during pressure regulation, so as to effectively prevent the fuel from entering the fuel injection nozzle.

在以前的工作經驗中發現，某些燃氣鍋爐的燃料供應係統僅在油泵的入口和出口配備了回油管，因此一旦油中帶水，將導致爐膛熄火。

In previous work experience, it is found that the fuel supply system of some gas-fired boilers is only equipped with oil return pipes at the inlet and outlet of the oil pump. Therefore, once there is water in the oil, the furnace flameout will be caused.

燃氣鍋爐各個係統的保養內容：

Maintenance contents of each system of gas-fired boiler:

1.爐體維護：為了使鍋爐經濟運行，有必要加強鍋爐的日常使用維護。這也是防止熱效率降低，避免使用條件惡化和鍋爐事故的重要措施。

1. Boiler body maintenance: in order to make the boiler operate economically, it is necessary to strengthen the daily use and maintenance of the boiler. This is also an important measure to prevent the reduction of thermal efficiency and avoid the deterioration of service conditions and boiler accidents.

2.燃燒器維護：清潔燃燒器杯盤，點火裝置，過濾器，油泵，電機和葉輪係統，對風門連杆裝置加潤滑劑，重新測試燃燒情況。

2. Burner maintenance: clean the burner cup and plate, ignition device, filter, oil pump, motor and impeller system, add lubricant to the damper connecting rod device, and retest the combustion condition.

3.控製器維護：檢查和維修電器部件，控製電路，清理控製箱中的集塵，並檢查每個控製點。進行密封處理，防止控製器部件受潮。

3. Controller maintenance: check and repair electrical components and control circuits, clean the dust collection in the control box, and check each control point. Seal to prevent moisture on controller components.

4.給水係統維護：檢修水處理裝置，檢查水質是否達標，清洗水處理係統，檢查給水泵的運行情況和揚程，檢查管道閥門是否靈活使用，斷水斷電，各係統充滿水後關閉閥門。

4. Water supply system maintenance: overhaul the water treatment device, check whether the water quality meets the standard, clean the water treatment system, check the operation and head of the feed pump, check whether the pipeline valves are used flexibly, cut off water and power, and close the valves after each system is filled with water.
