Electric steam how to maintain boiler in long shut down heated by resistance heating resistance heating, electric heating means is a steam boiler using resistive heating element for heating the tubular. Electric heating steam boiler is structurally easier superimposed combination, and the control flexibility, easy maintenance and replacement. Currently electric boiler basically using resistive heating element for heating the tubular electric boiler. Electromagnetic induction heating means, by the magnetic energy into electrical energy, and then the steel member is heated to a magnetic induction, a heating generates heat. Electric heating source is steam boiler electric boiler heating system, the heat medium is water, the use of electricity valley difference, at low power, electric heating timely open the steam boiler, the water in the tank is heated, heat, storage, backup power to peak time then. When the power supply peak power of peace, the need for timely close the electrically heated steam boilers, hot water heating continued storage tank, so as to save energy.
Boilers are widely used, and there are some unique problems in China. Although imported how to maintain boiler in long shut downs are used in some plants, the pipeline is still carbon steel, oxygen corrosion and CO2 corrosion are serious, resulting in the problem of iron ions in condensate water exceeding the standard is very common. High content of iron ion water is an unsafe factor in boiler, which causes pit erosion and pitting corrosion of boiler wall, and causes boiler perforation to be scrapped.
Coal-fired how to maintain boiler in long shut down not only seriously polluted air, which produces a large amount of waste water sludge can also cause serious water pollution and soil contamination. To protect the city of Tongren green water blue sky, since 2014, led by the city of Tongren City, Guizhou Bureau of Quality Supervision, of 10 steam tons / hour within built-up areas and Tongren City High-tech Zone, Economic Development Zone, Tai Lung range and below, in Guizhou tobacco industry limited liability company Tongren cigarette factory, Tongren City, drug rehabilitation centers, Tongren Wantong construction and development Co., Ltd. and other 36 enterprises of coal-fired boilers to carry out an intensive diagnostic investigation. One by one on the ground to verify the registration, and the companies signed an undertaking to ban coal-fired boilers eliminated; to effectively reduce the burden on enterprises, according to the spirit of the document, to take the initiative within the time limit or eliminate the use of coal-fired boiler unit to switch to clean energy, the after review and acceptance Municipal Environmental Protection Bureau, according to the amount of coal-fired boilers hour evaporation reward, award criteria tons of steam per 30,000 yuan subsidy.
Up to now, the city of Tongren out of 36 coal-fired boiler units, a total of 43.051 tons of steam, an award subsidies 1,291,530 yuan, so far, the city of Tongren jurisdictions total phase-out of all coal-fired boilers, and lay a good foundation for the creation of ecological civilization demonstration area.
Maybe people will think condensing gas how to maintain boiler in long shut down maintenance will be very complicated, it is not. Fast square each boiler at the factory, we will configure the product maintenance manuals, to make a series of operational requirements for the maintenance time and method.Free Chat
