2ton boiler manufactured
1, the calculated blowdown rate: an index showing a blowdown blowdown rate, i.e., blowdown water blowdown rate (Q sewage) percentage of the amount of evaporation 2ton boiler manufactured (Q vapor) is. Expressed as follows: K = Q sewage / Q vapor × 100%. When the amount of the boiler water stable, balanced relationship according to the amount found that a substance with the water supply into the furnace equivalent amount drained waste water with an amount of saturated steam and entrained. The (Q dirt + Q vapor) × S a = Q vapor × S vapor + Q sewage × S sewage where S a, S vapor, S sewage represent the feed water, saturated steam, the content of a substance in the sewage water, in the formula S the value by the salt content, can also be a component of the content (e.g., alkalinity, chloride ion) is calculated. Sewage is K = Q / Q vapor = (S a -S vapor) / (S -S sewage to) × 100%.
2, blowdown rate is calculated to be noted that the following three points: (1) can be calculated blowdown rate alkalinity or chloride ions (chlorine ions and salinity have relatively fixed proportional relationship, usually replaced by chloride ion salinity) were calculated blowdown rate, whichever is greater final values as blowdown rate, general heating boiler blowdown rate should be controlled below 10%. (2) for a large capacity boiler, because of its good effect of water separation apparatus, the humidity vapor is minimal. Such salt content is much lower than the saturated steam to water salinity, so in this boiler blowdown rate is calculated in both the salt content of the steam can be ignored, i.e., to K = S / (S sewage -S a) × 100% (3) for most industrial boilers, especially small volume of the drum, water separation device is simple, a large amount of water with saturated steam in industrial boilers, steam wetness often around 3% (control blowdown rate comparing the range of 5% to 10%, is already not too low) salt content can not be ignored when the steam boiler blowdown rate is calculated under this condition. Since K = (S a -S vapor) / (S -S sewage to) = CL- to / (CL- -CL- to sewage) -CL- vapor / (CL- -CL- to sewage)
The well-known and high-quality gas and hot water 2ton boiler manufactured enterprises of the old users usually have good reputation. Users who have used the equipment of the manufacturer share their own experience, and users can learn from the side how the boiler quality of the manufacturer is. Whether the boiler automation degree is high, whether the manufacturer service is sweet, and so on.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water 2ton boiler manufactured to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
First, a user should choose a suitable antifreeze as the case of the gas hot water 2ton boiler manufactured plumbing system. Many gas hot water boilers and plumbing systems used aluminum alloy material may be selected silicate antifreeze; however, the system for cast iron, it is necessary to add corrosion inhibitors, PH value is adjusted to between 8-9.
