How much of a natural gas boiler?
Boiler prices, the problem is each user in the purchase of equipment first consideration, which would allow the cost of inputs is more clear. For gas-fired widely used in recent years to start, too, and now the price of natural gas boilers on the market vary, many users purchase will be feeling confused. This is mainly due to the price factor in the region, equipment, materials, production processes, etc. caused mixed.
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
4, the shutdown operation
Turn off the main gas supply valve to stop gas supply, then circulating pumps and pump continues running water, when the boiler water temperature dropped to 70 or less, or about 4-6h stop after stop circulating pump and supply pump operation.
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.
