6 ton capacity used steam boiler for sale
A method of cleaning a boiler, a chemical cleaning process: descaling water rinsing → pickling → water rinsing → passivation; 2, independent of the other system is disconnected the boiler, the cleaning tank, the washing pump is coupled into the boiler with a closed cleaning 4, the end of the rinse water; loop; 3, in a simulated cleaning state washing system leak check, while the boiler remove loose dirt, at the outlet of the flushing water when no visual presence of large foreign particles, the end of the flushing water in circulation cleaning tank Add "Yunqing boiler cleaning powder", the main controlling the cleaning in 3-6% concentration, temperature in the range of 50-60 deg.] C, decontamination wash cycle within the system, cleaning time 2- about 3 hours. PH measured by pH paper Timing acid value of (1/20 minutes), it was maintained at 1 or less, when the pH value is stabilized within half an hour, and purge the system without gas evolution, the pickling process ends; 5, after passing rinse water, circulating add "Yunqing passivation pre-film" passivation to improve the corrosion resistance of boilers. After concentration of the whole system is stopped mixed solution was warmed to about 60 degrees cycle, soak for 2-3 hours, the passivating liquid discharge system, the cleaning process is ended. Note: 1, this product can not be eaten; 2, process handling, operation, wear protective clothing. Packing: plastic bags: 1 kg / bag 25 kg / bag.
What should be seen to distinguish the quality of gas-fired condensing boilers?
Gas-fired condensing boiler is a new type of energy-saving and environmental protection equipment nowadays. Its working principle is to utilize the exhaust temperature of gas to make full use of its heat, which greatly improves the thermal efficiency of gas. At the same time, in the process of gas exhaust, some harmful substances can be removed to purify the exhaust gas. As more and more gas-fired condensing boilers are available on the market, how can we identify a reliable, high-performance gas-fired condensing boiler from a wide range of products?
Waste heat recovery boilers may be horizontal or vertical shell boilers or water tube boilers. They would be designed to suit individual applications ranging through gases from furnaces, incinerators, gas turbines and diesel exhausts.
After use throughout the winter, the Central Conservatory of Music give us feedback, six V6-99 fully meet the heating needs of the school. And boiler fuel and water requirements are not high, urban water and low-pressure natural gas combustion can operate. The most important point is that nitrogen oxide emissions are very low and very happy to recommend it to others to do the brother of boiler units. --customer feedback
