combined hot water and heating systems boiler
In combined hot water and heating systems boiler 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.
How condensing gas furnace functions: gas condensation in the furnace during operation, as with a conventional combined hot water and heating systems boiler, water is heated by the heat of combustion. Combustion flue gas is typically discharged through the flue. Thus, the heat in the flue gas will be exhausted to the outside. However, the flue gas condensation technique may be utilized. Since the flue gas is composed by a large number of high-temperature steam, condensation techniques may utilize flue gas heat, and then the heat acquired input heating circuit.
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam combined hot water and heating systems boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
