hot sale WNS boiler for heating

3, pressure transmitters

The steam pressure in the boiler into a continuous pressure signal, direct touch-screen displays the current pressure, automatically adjust the steam pressure, and stable operation of the boiler, and to save energy (from Danfoss).

Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new hot sale wns boiler for heating equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).

Working principle of steam-steam separation unit on steam hot sale wns boiler for heating

In the overall design of steam boiler, the steam separation device is essential, it is an important link to quickly separate the moisture contained in saturated steam, which can be used to improve steam dryness and ensure the normal operation of the boiler. Convenient and meet the needs of users. Then, I will lead you to understand the steam boiler steam separation unit working principle.

In hot sale wns boiler for heating feed water or boiler water, why should we increase phosphate? What should pay attention to? In order to prevent calcium scale and corrosion in boilers alkaline, addition of phosphate in boiler feed water, boiler feed water into the furnace with the making of Ca2 + will not the formation of scale, but generated slag, and to be excluded by the boiler blowdown. This approach to the boiler feed water dosing phosphate phosphate treatment called boiler feed water. In boiler water phosphate solution was added, good control of a certain amount of phosphate (PO43-), produced under basic conditions as follows: dibasic calcium phosphate generated is referred to, the slag is a soft, easily with boiler blowdown away. Therefore, as long as control of boiler water volume PO43-, you can make the Ca2 + content in boiler water is very small. In actual production, is usually formulated with trisodium phosphate () or sodium phosphate () to 5% to 8% of the liquid, through the filtered residue, and then a 3% solution of water supply dubbed, boiler water it added directly or added boiler feed water, boiler and how much to increase the amount of water Ca2 + amounts, generally have to be determined by the debugger. Phosphate treatment boiler water is not volatile substances to add salt to the water boiler, the boiler will increase the salinity of the water, in order to ensure that the effect of boiler water treatment, without affecting the quality of steam and hot water, must pay attention to the following questions: (1) to the boiler feed water residual hardness smaller, should be more removed during feedwater softening Ca2 +, Mg2 +, in order to avoid too much slag generated in the water in the boiler, increasing the blowdown boiler even affect the steam quality. (2) the internal boiler water should maintain a predetermined excess amount of phosphate root. Further, dosing should be uniform, the speed is not too fast, so the water in the boiler sudden increase in salinity, affect the quality of the steam. (3) should be generated to drain away the water residue, so the boiler water gathering a lot of slag, affect the quality of steam. (4) for the boiler fouling, phosphate dosing during treatment, the scale must be removed first. Because the roots can act with phosphate limescale originally generated, so that the scale becoming detached slag, so that a large amount of water in the boiler water to generate steam to affect the quality of the slag, scale shedding severe clogging of the tubes will be even, resulting in circulation malfunction. (5) adding the drugs should be relatively pure, so as not to cause contamination of the pot and steam boiler corrosion and deterioration of quality. Pharmaceutical quality is generally should meet the following criteria: content of not less than 92%, the insoluble residue is not more than 0.5%. When dosing, the drug should be combined with the sewage, so as to avoid adding new agents are leaving the boiler. Regular or continuous dosing accordance with the provisions regular and continuous blowdown. Regular testing boiler water, to determine the dosage according to test results.
