Industrial cashew boiler machine price in china water quality standard industrial boiler water quality standard industrial boiler water quality standards for a range of industrial boiler water quality standards of this new standard specifies the quality requirements during operation in industrial boilers. This standard applies to the outlet steam pressure less than the rated 2.5MPa. Water as a medium and fixed in steam boiler steam boiler water as a medium is also applicable to a given water as a medium pressure hot water boiler and pressure hot water boiler. Second, the industrial boiler feed water quality standards 1. Steam boilers and steam boilers are generally required to use chemical water treatment outside of the pot, and the water quality must meet the requirements in Table 1. Tends to 1) hardness Lc basic unit (1 / 2ca2 + 1/2 Mg (2+), the same below .2) alkalinity MMO1 / L basic unit is C (OH-, 1 / 2CO2-3, HC03 -). On the alkalinity index value is not high boiler after reporting to the local boiler and pressure vessel safety supervision mechanism no overheating, which can be appropriate to relax the limits on the alkalinity index. 3) When the amount of evaporation than or equal to the nominal 6t / h boiler should be oxygen, localized corrosion was found, measures to be taken deaerator feed water, the oxygen content of the boiler feed water or steam turbine should be less than when less than 6t / h boiler rated capacity equal to 0.05 mg / L. 4) If the dissolved solids is difficult to determine, by measuring the conductivity or chloride ions (C1 -) indirect control, but the relationship between conductivity and dissolved solids or dissolved solids and chloride ions (of Cl-) ratio should be determined EXP . food. This ratio relationship should periodically re-tested and corrected. 5) only fuel, gas boiler 2, equal to or less than the rated capacity 2t / h, and less than or equal to 1.0MPa rated steam pressure, steam boilers and soft drinks dual boilers (steam, no special requirements such as quality) and the metering process can be application. But we must strengthen the boiler scaling, corrosion, monitoring water quality, good feeding, sewage and cleaning. Boiler water quality should meet the requirements of Table 2.
Ukraine industrial construction quality, customer Ukraine's current visit to our company is very interested in industrial steam cashew boiler machine price in chinas. Our technical staff will fast one side condensing gas steam boilers, steam pipes condensing gas boilers and other star products, from performance to the advantage of his right to the customer. Natural gas is clean, easy to use and other advantages, is to use one of Ukraine accounted for a large amount of the type of energy. Fast boiler since its inception in 1998, with great concentration R & D and manufacturing of gas clean fuel boiler, has a very extensive industry experience, and to respond positively to the pace of global environmental development for the market launch of the gas boiler is not only the thermal efficiency is very high (up to more than 108%), emissions of harmful substances is very low (less than 18 nitroxides mg / m3).
Whether it is a steam boiler or a hot water boiler, after the boiler is installed, a hydrostatic test (ie, water pressure) must be performed. Because of long-distance handling, loading and unloading, installation, it is inevitable that collision and damage, through the water pressure test can find the boiler defects and take appropriate measures in time to ensure the boiler operation safety. The following is an example of a fuel gas boiler water pressure test:
Process cycle gas steam cashew boiler machine price in china and hot water circulation pump gas steam boiler with a heat exchanger can be achieved bathing and heating dual function. Natural circulation gas steam boiler, inlet and outlet are taken over from the top of the drum, the water from the water distribution pipe guide and drop into the front side lower header pipe, through the waterwall tubes heating rise. The front drum, rear end plate is provided with impermeable boundary falling rising flow, only the lower half of the drum cross-impermeable partition plate. For the forced circulation, the water access to the front end of the lower header, the front drum increases to upper waterwall tubes (waterwall downcomer Cancellation time), and then transferred to the waterwall tubes downcomer side to side lower header, then into the side of the cloth water wall tube rose to the drum, and from the front row convection bank down to the next drum, and finally between the upper and lower drum and several circuitous flow of water from the rear end of the drum. Hot gas steam boiler by circulating hot water tank insulation circulation pump, the hot water heating cycle tank, may be achieved bath object; circulation pump for circulating water through the hot water heating conduit, through the heat sink (radiator) can reach the people heating requirements.
