When gas boiler ignition, need to pay attention to what matters is the primary determinant of the ignition gas boiler started to master boiler ignition precautions to ensure the safe and stable operation of the boiler. 1, for gas-fired boilers, the ignition time if not successful, the need to purge the furnace flue, before a second firing. 2, in order to prevent a gas explosion, gas boilers not only to purge the boiler furnace and flue gas channel before the start, the need for a purge gas supply pipes. The gas supply duct media typically purged with an inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace flue with a certain flow rate is the flow rate of air. Case 3, in the rear of the boiler did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case. 4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, it is necessary to detect smoke components, to avoid too high excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.5 , real-time attention should fireman switch case of a gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valves, only put into operation is determined normal. 6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion. 7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close air release valve. 8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, should contact the gas company. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter. 9, should comply boiler unit boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. When there are unusual circumstances and can not solve the problem, depending on the nature of the problem promptly contact boiler plant or gas company, to conduct maintenance by a professional maintenance staff. 10, shall comply with the provisions of the relevant gas. Not free to fire the boiler room, prohibited welding, gas welding and other operations in the gas pipe roadside.

Former steam plant boiler equipment, Enterprise is also important to bring quality inspection departments and pressure steam boiler plant equipment to detect Branch signed "boiler installation started application form" to everyone territories have agreed to the "quality of the installation agreement responsibility", by the Division of the detection means complete steam boiler plant quality monitoring.
For new people to take over, we should note the following: First, check whether the diameter required pressure wns series hot water boiler diesel fired boiler is a boiler body openings with the same atmosphere, in any condition, boiler water level in the table are zero pressure boiler. Therefore, before use, the user should check for new boilers, in particular, check whether the diameter to meet the requirements. Further, the communication tube should be prohibited in any valve provided to ensure smooth takeover. Generally, professional supply of pressure hot water boiler will spray "pressure boilers may not use pressure and hot water outlet temperature should not exceed 90 ℃" warning labels in the apparent position of the furnace. Second, installed by professionals, debugging initial purchase use, pressure hot water boiler manufacturer will recommend the installation and commissioning of the boiler by professionals to be responsible. Once operational, non-professionals are not allowed to change the structure of the boiler, free installation system piping, valves. At the same time, attention should be converted must not use pressure hot water boiler. Third, to ensure the safety of boiler accessory is a sensitive and reliable long-term use pressure hot water boiler you know, regularly fixed on the pressure gauge and thermometer professional check to ensure parity within the validity period.
