The gas tube boiler drum was SZS "D" type arrangement, compact structure, drum and other major components are not directly affected by the high temperature flame radiation and erosion, higher safety standard. FGR by the same flue gas recirculation techniques so that NOx is less than 30mg / m³, is an excellent choice for large industrial enterprises.
Why gas household hot water boilers in copper tube rupture it: ① water quality does not meet the formal standards, initiative without treatment, leading to the formation of scale pipe wall, affect the heat transfer effect, produce overheating tubes, strength weakens; ② boiler structure is not ideal, no circulation good, leading to local temperature is too high or because of improper manipulation start, so that the outer tube is formed coke; ③ at regular wear, thinning of the pipe wall; ④ tube mainly the mass, coarse material, or if the quality of the weld; ⑤ mentioned effect of temperature or cool down too fast down the drain, so that uneven heating pipes, resulting in breakage of the weld; ⑥ heat feed water is too low, so that the line is generated due to uneven heat changed appearance, resulting in seepage of the expansion port. Suddenly no electricity when the gas hot water boiler operation how to do gas-fired boiler | fuel boilers | steam boiler Environmental Equipment Co., Ltd.
In mid-April, Hohhot, Inner Mongolia issued a notice (hereinafter referred to as the "Program"), "Hohhot tackling air pollution control plan" (2018-2020), the "plan" to win tough fight pollution prevention, to promote air pollution control, as the city to create a pleasant living environment for the development of the measures.
For air pollution control, "plan" set goals. As of 2020, Hohhot air quality more than two days ratio reached 83.8%, fine particles (of PM2.5) concentration of 35 micrograms / cubic meter. Wherein, 2018 Hohhot air quality objectives: good percentage of days to reach 79.5%, fine particles (of PM2.5) concentration of 39.2 micrograms / cubic meter.
Since 2017 to enter the heating season, Hohhot is the air quality continues to improve, has introduced the autumn and winter air pollution in Hohhot comprehensive reform program "," Hohhot 2017--2018 autumn and winter special inspection of comprehensive air pollution control program of work of law enforcement. " "Hohhot 2017--2018 autumn and winter air pollution in the comprehensive management of supervision and inspection plan", "Hohhot environmental Protection Agency checks on the issuance of the work program of the winter heating enterprises notification", "Hohhot City people's government on the issuance of residential heating clean alternative , "and other series of notifications. Key measures to coal-fired boilers for heating and bulk coal governance.
Second, the city's coal-fired boiler coal yard, residue field to achieve full closure transformation; more than 20 tons of steam / h coal-fired boilers have been installed pollution-line monitoring equipment, and networking with the Municipal Environmental Protection Bureau, established a 24-hour monitoring system.
Through the above measures, Hohhot air quality improved significantly compared to the same period. January 1, 2018 --3 17, good days Hohhot total 66 days, an increase of 4 days last year. Sulfur dioxide concentrations decreased 40.7% over last year, PM2.5 concentration decreased by 20% over the same period last year.
According to (2018-2020) spiritual requirements "Hohhot tackling air pollution control plan", 2018, the Board will eliminate 35 tons of steam utility / h coal-fired boiler room 11 - 15, involves heating an area of 3.872 million square meters. Currently the demolition and integration of clean energy and the transformation is complete, out of the task have been put in place, we have been completed out of eight coal-fired boilers and boiler room of the grid work, removal of nine coal-fired boilers (grid yet dismantled three, to electricity yet dismantled three), and has been able to "break two three clear", the remaining boilers will be completed by the end eliminated.
Gas boiler gas burner configuration and alarm means if necessary a gas burner in the gas boiler 1, which is what constitutes the? Gas boiler gas burner, in which the configuration, there are mainly the following, are as follows: air supply system: its role is fed certain amount of air into the combustion chamber in order to smooth combustion. The main components thereof, is a housing, a fan motor, an impeller, a controller damper, the damper flap, and the cam adjustment mechanism like the diffuser plate. Ignition system: mainly used to ignite the mixture of air and fuel, the main components thereof, for the ignition transformer and the ignition electrodes. Monitoring system: the main burner is to ensure safe and stable operation of the components included in the main is a flame detector, the pressure detector and the temperature detector and the like. Fuel system: its main role is to ensure the combustion of the burner can be smoothly provide sufficient fuel. Its main components, is a filter, pressure regulator, a solenoid valve, and a fuel such butterfly. Electronic control system: this is mainly to a programmer, and for different burners, there is a programmable matched filter. 2. Gas boiler, it is necessary to install an alarm device? This kind of boiler gas boiler, it is necessary to install an alarm system, because, in GB50041 "boiler room design specifications" in this standard, there is a clearly defined and requirements. So, on this issue, the answer is yes. Further, in the alarm device, for the concentration of combustible gas alarm device. 3.0.5 tonnes of gas-fired boiler, its gas consumption is 40 cubic meters / second it? 0.5 tons of gas boiler, which gas consumption in the calculation, specifically, it is as follows: 0.5 tons gas boiler, its power is about 350KW, converted into heat is 350 kJ / sec. So, every hour that the required heat for 1.26 million kilojoules. If the gas calorific value is 37800 kJ / cubic meter, so that gas consumption is 1.26 million / 37800 = 33.33 cubic meters. Taking into account the boiler efficiency, then, so it should be about 40 cubic meters.
