3, high total condensation heat transfer technology

Condensing gas condensing boiler technology is efficient in many condensing type of equipment is technically a big advantage, but also one highlight of condensing gas boiler, after all-condensing heat exchanger technology, higher heat exchange rate in the course of their work, replacement of heat more, while improving overall productivity but also enhance the efficiency of other processes.

Hot water boiler should be cleaned regularly with hot water boiler overhaul to the timing of its finishing and maintenance, eliminating potential threat, but also the timing of its identification and testing. Check electric boiler inside there is no scaling or corrosion, while viewing their welding there is no gap or crack, do not underestimate that little slit, attack the source of some dangerous trouble is precisely that. Take a look inside the tube there is no wear and corrosion, especially at the interface wall. View pipes have not presented twists and turns, drum kits, depression, overheating and so on. Metal temperature on the electric boiler equipment also want to see, once overheated cooling is necessary to adopt appropriate treatment. Check whether the automatic control systems and related instrumentation also robust and flexible to use.

Condensing heat recovery boiler comprises a latent heat of vaporization and sensible heat of the water vapor portion of the high temperature flue gas. Recovering sensible heat change with decreasing flue gas temperature is not great; recovered latent heat of vaporization of water vapor as the temperature decrease vary greatly, when the higher exhaust gas temperature, very little recovery of latent heat, with significantly lower exhaust gas temperature, the recovery of latent heat increases rapidly, and subsequently stabilized, condensed from the point of view, the difficulty of flue gas condensation of the flue gas with decreasing temperature and increasing.

For the 2018-2019 autumn-winter air pollution prevention and control work, Jinhua City, Zhejiang Province issued a public draft, mainly in the autumn and winter to reduce heavy pollution weather Development frequency.

Take measures to reduce coal comprehensive, non-electric focused on reducing the total coal consumption, in 2018 the city's total coal consumption reduction of 1% compared with 2015. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption of the same amount of capacity reduction or substitution, elimination of energy consumption, water consumption, environmental protection and safety is not up to 300,000 kilowatts coal-fired units. Development of industrial parks "One District One heat source" action plan, and more than 300,000 kilowatts coal-fired units were heating transformation, promote backward and shutting down small coal-fired thermoelectric integration of coal-fired boilers in the range of 15 km radius of the heat. Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, to the new "coal to gas" projects, should adhere to increase coal gas reduction synchronized to gas will change, the premise of the gas supply contract signed and orderly implementation.

Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation to ensure that no dead ends, no blind spot. Investigation and the coal-fired boilers to register one by one.

According to the law to increase the city's efforts to phase out coal-fired boilers in accordance with regulations. Before the end of December 2018, the city basically out of 10 tons of steam per hour of coal-fired boiler, built-up areas out of 35 tons of steam per hour coal-fired boilers. Complete 1 set (Yiwu) per hour, 40 tons of steam coal-fired boilers transformation of ultra-low emissions, coal-fired plants to achieve ultra-low emission levels.

In principle, the boiler NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. New installation and reconstruction of gas-fired simultaneously supporting the low NOx combustion device.

Biomass boilers to carry out a comprehensive investigation, complete control of boiler scale, distribution, fuel, furnace, pollution control facilities and pollutant emissions, and establish a list of management accounting. Yan Gesheng biomass boiler registration, strictly control the new urban area of ​​biomass boilers. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of ​​biomass boilers ultra-low emissions transformation. For existing biomass boilers, environmental inspection carried out one by one, there are multiple distributed biomass boilers, the implementation of the demolition of small and large industrial agglomeration area.
