hot water boiler central heating for hotel

No matter what the quality of the gas-fired boiler purchased, even if any problems arise during installation, it is impossible to make good use of the gas-fired boiler. There are a lot of things we need to consider when installing, so let's take a look at what needs to be noticed: first of all, the installation location, because gas-fired boilers are used to provide thermal energy. Therefore, the surface temperature is very high, so the installation of gas-fired boilers should be as much as possible to avoid contact with the human body. The installation location should be chosen as far as possible around the corner or edge do not interfere with the passage of people, this is The first thing to consider when installing.

In 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.

Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of ‚Äč‚Äčtourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast boiler steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .

Real quality steam boiler to provide more high-quality steam at a safe and convenient for our premise, to make our lives work more convenient. For steam boiler we should use the time to pay attention to his maintenance work, so as to make it even more long-term help for us.
