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 machine price (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)
A maintenance requires the operator to work in peacetime, of boiler machine prices and auxiliary equipment inspection records, mainly for combustion equipment, water gauge, safety valves, fans and other equipment, the equipment must state record for later inquiry.
Many users find that boiler machine price technology consultant at the time of introduction gas hot water boiler with heating, usually recommend more than two or two with the use of boilers; some users really do not understand this, I think manufacturers to gain profit, deliberately users select more than one boiler, it is not true, behind doing so is of great significance. 1, when the weather is not too cold, the user can choose to start one or two boilers operate at optimum operating load. 2, when the boiler requires servicing and maintenance, a table may be stopped, either high-load operation other boiler, so as not to delay the normal heating demand.
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler machine price paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
