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 boiler (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)
Industrial gas condensing boiler works and the core technology of industrial gas condensing boiler, by definition, it is a condensing gas boiler. Currently, condensing gas boiler can be divided into commercial gas condensing boiler and condensing gas boiler industry. Products are also different from the horizontal condensing boiler and condensing boiler vertical. The most important is to realize the nature of condensing boilers condensing technology. The key industrial condensing gas boiler condensing boiler key point is to use the condensing technology, which is a relatively new type of energy-saving and environmental protection technology. In fact, the principle is not complicated, the simple conclusion is that to recover the heat energy of the flue gas through the flue gas condensation. In general, the traditional boiler thermal efficiency of only 85% or 91%. The exhaust gas boiler condenser temperature was lowered to 35-60 ℃, full recovery of latent heat and sensible heat in the flue gas water vapor. Maximum thermal efficiency of up to 108.9%. Industrial works condensing gas boiler works condensation gas boiler is the hot flue gas discharged from the combustion boiler (typically from about 140 deg.] C) recovering the energy, the temperature of the exhaust gas after recovering only about 60 ℃. Thus, the thermal efficiency is improved about 10%, about 10% gas savings. Meanwhile, in the process of energy recovery, it is also possible to reduce harmful emissions, reduce environmental pollution.
