steam boiler

Henan knowledge base of questions and answers a gas boiler, which requires special Henan gas boiler overpressure test there? (1) test pressure is 1.25 times the pressure of the bubble. (2) is generally carried out once every six years, according to the case by the chief engineer approved the extension of reduced reported to the competent department. (3) water temperature was 30-70 ℃ (4) Experimental procedure: ① Sheung advance, prolong the duration of the low pressure. ② hydrostatic pressure test to check the work. Overpressure experiments at ③1.25 times the working pressure, continued after 5min, and then down to the working pressure, in order to start checking. Second, Henan gas boiler combustion regulation purposes? (1) stabilized to maintain normal steam pressure, steam temperature of steam amount. (2) stable ignition, combustion central appropriate, uniform distribution of the flame, the burner does not burn, superheaters and other equipment, to avoid coking. (3) the operation of the unit to maintain the highest economy. Third, Henan gas boiler why should dosing? (1) with calcium and magnesium salts remaining in the pot water mixture, the precipitate was a loose state, then discharged through the discharge, the salts preventing formation of scale within the heating surface. (2) reacting the pot water hardness, PH value appropriate increase, helps prevent drum, Wall acid corrosion occurs, silicic acid to reduce the vapor carrying the selectivity. Keep the boiler normal dosing, to maintain an appropriate amount of excess phosphate ions, Henan is an important measure to prevent the gas boiler fouling.

There are many reasons to upgrade a hot water or steam boiler, such as quieter operation, less greenhouse gas emissions, and increased reliability. Cutting fuel costs with a high-efficiency boiler can save a business a lot of money as well.
