negative pressure large office building vacuum boilers

Recently, Jinan City issued a "supplementary notice on accelerating the city's negative pressure large office building vacuum boilers-depth treatment of work-related" and formulated the following objectives.

I, on the in-depth treatment of boiler completion time. Low Nitrogen transformation and the transformation of the city's ultra-low emission gas-fired boiler biomass boiler to complete the appropriate time to relax, and strive to be completed in the end of June 2019, due to the commitment of heating (cooling) or involving people's livelihood and other support complex transformation process of the boiler furnace, indeed practical difficulties, completion time may be extended to the end of October 2019.

Second, on the in-depth treatment boiler standards. According to the "program tackling autumn and winter", the low nitrogen gas boiler after transformation, in principle, is not higher than the concentration of nitrogen oxides emissions of 50mg / m³, according to encourage the transformation of 30mg / m³. Encourage the transformation of biomass boiler with ultra low emissions coal-fired power plants.

Third, on the time-depth treatment of boiler arrangement. 2018 10 completed before the end inventory information verification, planning work; organize the implementation of the completion of the work before the end of May 2019; the end of June 2019 to complete the inspection work (due to heating and other disabled do not have to bear the acceptance conditions, available at the end of November 2019 before the completion of acceptance).

Fourth, on the information submitted to the work. Please ring the economy Zi [2018] No. 175 document complements the "Jinan City gas boiler investigation Summary Sheet" on or before October 12, "Jinan biomass boiler investigation Summary Table" to the Municipal Environmental Protection Bureau. On or before October 26, the "Jinan City Boiler depth management plan summary table", "Jinan hole sampling and sampling platform standardization construction unit summary table" and has completed the in-depth treatment of the boiler reconstruction proved supervisory monitoring report submitted to the Municipal Environmental Protection Bureau . Since the beginning of November, every Friday morning before 10:00 (for the first time submitted November 2) the progress of reform in-depth treatment of each unit case to the Municipal Environmental Protection Bureau.

Sources of air and air vapor hazards of what? Air and non-condensable source gas: after a negative pressure large office building vacuum boilers shut down, a vacuum generating suction air; feed water into the boiler; feed water and condensate in the intake air is exposed to the atmosphere. Air hazards: there is an air steam heating system, not only can cause corrosion of pipes and equipment, but also reduce the heat transfer performance of heating equipment, the impact of condensate recovery, resulting in waste of energy.

Such vacuum phase transition negative pressure large office building vacuum boilers mostly imported burner, combustion efficiency, low noise and exhaust emissions. Internal exchanger made of stainless steel, in this regard to ensure high heat transfer efficiency, on the other hand can ensure a clean water quality. At the same time, its smoke tube interior spiral spoiler, in order to improve heat transfer efficiency, and lower operating costs. Further, it is the overall use of square configuration, the boiler and the heat exchanger is a one-piece design, so that a small volume of its structure compact shape the United States.

Changsha vacuum hot water negative pressure large office building vacuum boilers which company is good on the current domestic vacuum hot water boiler manufacturer, refer to contribute different, each with their own advantages vacuum boiler water sample. I do not know whether to explore the vacuum hot water boiler in question covers what professional standards. Generally speaking, you want the right to choose suitable vacuum hot water boiler units, following are some specifications must know: First, the efficiency indicators vacuum hot water boiler Second, the thermal vacuum hot water boiler speed Third, identify the vacuum hot water boiler output Fourth, the style vacuum hot water boiler of some of the above specifications, procurement vacuum hot water boiler should be a general failure, and most certainly the fault of scruples, some of this specification, it should be understood that a group of vacuum hot water boiler if there are problems benefit of course, the selection of vacuum hot water boiler of the day, you select the most appropriate to a unit price of vacuum hot water boiler is the most first.
