application of scale in boiler water
How should conclude that there is lack of water steam application of scale in boiler water event when the water level has long been inferior to the minimum level prescribed, but still be able to see the water meter in the water level, the contractor for the slight lack of water; when the water meter is less than the visual level, the severe sentence lack of water. The induction phenomenon include the following: (1) level inferior to a predetermined sub-routine drum level; (2) low level alarm, an audible alarm, warning lights; (3) the temperature of the steam superheated vapor is increased; (4) provided water is not a conventional, less steam flow; (5) the temperature of the exhaust gas water vapor increases.
In recent years, the country frequent application of scale in boiler water explosion hurts. In order to boiler explosion hazard within the city limits of strangled in the cradle, Tongxiang City, Zhejiang Province Environmental Protection Bureau began efforts to expand the investigation and remediation action on the bathroom boiler.
To strictly implement the ban on burning district requirements, to further improve the quality of urban environment, improve ecological satisfaction, since mid-February this year, Tongxiang City, four environmental protection will be co-related units Indus streets, to carry out this major investigation large heating boilers campaigns, decided to launch a big investigation on urban use hot water bath, foot bath shops, hotels and other business, the use of high-polluting fuel combustion zone ban on large renovation of heating boilers, continuous efforts to fight the "battle of the sky" .
According to preliminary statistics, the use of hot water units to provide services related to nearly 100 within the city limits, as of now, the investigation related to environmental protection has four units of 65, found that the use of biomass boilers 6 sets, 1 small coal-fired boiler units, diesel 1 small boiler units.
According to the investigation objectives edge side of remediation, environmental protection and the use of four pairs of high-polluting fuel boilers Daihatsu small bathroom has been ordered to stop using it immediately; the use of biomass boilers units of gold Water Cube, has been ordered to make corrections, use clean energy heating or hot water outsourced way.
"After a major renovation a few years ago, the small coal-fired boilers have been basically eliminated banned, but there are still dynamic changes and new heating boilers. Next, we will continue to carry out large investigation heating boilers, within city limits investigation and implementation of full coverage, and we will also carry out rectification 'look back', initially planned to be completed this major investigation big campaigns before the end of April. "Zhu Yaming, director of environmental protection four said Tongxiang three cadres of the Conference" seven action "mobilization meeting sounded the full implementation of" urban quality improvement action "horn, as" beautiful Tongxiang "vanguard construction, environmental protection and ecological environment people will be" two upgrade two down "as the goal, create beautiful ecological upgrade urban quality, Tongxiang boost economic and social development of high quality, is to make people's lives better and make unremitting efforts.
ZG is an autoclave steam sterilizer manufacturers in China with 70 years experience since 1945. But, some people cannot understand autoclave steam sterilizer very well. Usually autoclave can be match with horizontal steam application of scale in boiler waters. Now, we will talking about what is autoclave steam sterilizer.
Gas application of scale in boiler water 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.
