What problems should be paid attention to in maintenance Electric normal pressure Boiler
Nowadays, advanced electric atmospheric pressure boilers need to be used in industrial production as well as in daily life. However, the electric atmospheric pressure boiler is a highly operational mechatronics equipment, such as customer inspection, maintenance is not timely will result in equipment line aging, equipment oil circuit and oil pump wear and so on. Therefore, users need to pay attention to the maintenance of equipment when running boilers, then, what problems should users pay attention to in the maintenance of electric pressure boilers with good performance?
1, pay attention to stop furnace detection electric atmospheric pressure boiler in the maintenance, users should let the equipment according to the normal shutdown procedure operation to achieve slow cooling, at the same time, Users should use pot water circulation and furnace ventilation to gradually reduce the temperature in the pot and furnace. It is worth noting that when opening the door hole of the equipment, users need to pay attention to preventing the burning of steam, hot water and flue gas in the boiler.
2, note that when users maintain the insulation, the combustor and flue of the detected atmospheric pressure boiler should be separated from the total flue or the other running boiler flue. The test results are as follows: (1) the combustor and flue of the tested atmospheric pressure boiler should be separated from the main flue or other running boiler. And the flue gate should be closed tightly, and in the partition after ventilation. In addition, the blind plate used in equipment partition should have sufficient strength and hardness to avoid being bulged by high pressure medium in the operation of electric normal pressure boiler, and the partition position should be clearly indicated to avoid confusion.
3, note that the user must completely cut off the connection pipe between the vessel and the gas equipment, especially to the combustible and toxic medium equipment before the inspection of the atmospheric pressure vessel is carried out by the user of the equipment container. In addition, the equipment container not only needs to close the equipment valve, but also needs to use the blind plate of the equipment to close the valve so as to prevent the gas leakage into the container and cause the fire explosion or poisoning accident of the valve so as to cause the combustible or toxic gas to leak into the container.
How to select the pressure hot water boiler? Cold days, as long as the use of pressure hot water boiler in places where you can feel like spring-like warmth, enjoy the convenience brought by the hot water. Value of pressure hot water boiler so that greatly enhance the user's quality of life. Pressure hot water boiler easy to use, but at the time of purchase the user must also confused how to buy, then we look at how the selection pressure hot water boiler? 1, determining the purpose of buying boiler pressure hot water boiler needs to be considered due to the differences in the use of the environment will vary, if the user only needs heating, you should select a dedicated pressure hot water boiler heating by hot water circulation pump the hot water circulation pipes, re-use radiator is a radiator to heat to every corner; just select the hot water supply dedicated by hot water circulation pump hot water tank insulation so that the cycle can be supply of hot water; it is also necessary Some users have a choice of two, it may choose to increase the heat exchanger in the pipe system use either of pressure hot water boiler. 2, the heating area is determined, an optional pressure hot water boiler water to determine the heating area or the amount of hot water needed to use the place, and then through the circulation amount of the boiler design calculation, precise scientific calculation and design can meet both do not waste resources. 3, to determine the fuel pressure hot water boiler in the style electric hot water boilers, coal-fired or gas hot water boiler which three of the more common, electric water boiler dzp 151 15d for energy is electricity, so coal-fired hot water boiler is to use coal gas or gas as an energy source.
Four advantages pressure hot water boiler pressure hot water boiler as a commonly used heating equipment, widely used in various occasions to people's daily lives has brought great convenience, not only saves a lot of resources and created high economic efficiency at the same time on the market has also been warmly welcomed by many users, and has been in demand ever-increasing trend, while customers adhere to the selection pressure hot water boiler is mainly because of this four technological advances of this type of boiler. A cheap price pressure hot water boiler itself is not high, coupled with the use of natural gas and other fuel prices in recent years also declined, pressure hot water boiler efficiency, so that the selection pressure hot water boiler the lower cost. In addition durability of high pressure hot water boiler and maintenance and it is very simple and convenient, so use better economy. Second, the high pressure hot water boiler efficiency using three layout design process, which is wet-like structure so that the heated area of great pressure hot water boiler, while the flue gas condensation recovery tail can be well controlled high temperatures generated when the exhaust pressure hot water boiler so that the use efficiency of the boiler is improved. Third, the security and stability of good pressure hot water boiler brand manufacturers at the factory is equipped with an alarm system for the boiler temperature, overpressure alarm systems, alarm systems, and leaking water and flame protection systems and other safety accessories, so that pressure hot water boiler safety when stronger, more stable. Fourth, the small size pressure hot water boiler generally uses quick structure, the bottom of the package boiler have adopted extremely rigid material, more compact size more convenient transportation and installation space requirement for the use together with not high in suitable for use in a variety of different environments. These are the four main advantage of pressure hot water boiler, these advantages are also a lot of customers are willing to choose and stick with the main electric hot water boiler heating under pressure. But pressure hot water boiler in actual use requires the operator to be checked regularly timed debugging, for safety near to promptly check its integrity in order to ensure a more secure boiler operation.
Recently, Hebei Province issued the Notice on governance oxides of nitrogen gas boiler.
It reads as follows:
Municipalities (including Dingzhou, Xinji) people's government, security male New Area Administrative Committee:
In order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, win the Battle of the sky, it now follows nitrogen oxide gas boiler notice governance:
First, we attach great importance to understand the situation, do a solid job governance
Nitrogen oxide gas boiler control, is to win the Battle of the sky, to promote an important measure to further improve the quality of atmospheric environment, is to deepen the air pollution control efforts around one main direction, is an important part of governance to deepen the boiler, the province's existing gas 10,790 tons of steam boiler units 37318, 23838 9,932 tons of steam wherein steam 10 tons / hr or less and a gas boiler, substantially free of nitrogen oxides into the process, the nitrogen oxide emissions of about 38,500 tons, the average concentration of about 150mg / m³.
Meanwhile, the province average concentration of nitrogen oxides is high, annual average concentration of nitrogen oxides is much lower than the rate of decrease of sulfur dioxide, haze is generated, among the major causes of the high ozone concentration.
Beijing and Tianjin to the surrounding gas on boiler control arrangements, and achieved initial success, Beijing completed the transformation of low - NOx combustion gas, nitrogen oxide emissions concentrations within 30mg / m³, the total emission reduction of 80%; Tianjin local emission standards promulgated boiler air pollutants, nitrogen oxide emissions concentrations within 80mg / m³.
Localities must deepen understanding, with a strong sense of political responsibility and the courage to act in the spirit of reinforcing initiatives, compaction responsibility to carefully organize governance, and make new contributions for winning the Battle of the blue sky.
Second, focused, clear goals, and win the battle governance
All localities should strengthen awareness of time, reasonable arrangements to ensure on schedule to complete the task, to the end of June 2020, the existing non-electric gas steam boilers, hot water boilers, Stoker stoker furnace and completed the transformation of low-nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³, 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler to install air pollution automatic monitoring facilities and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to install the nitrogen oxide gas boiler exhaust gas analyzer, a field inspection data should be able to provide emission monitoring at least one year.
