Third, the sheet type table

By professionals who understand condensing boiler they use steel production, but added amount of each component in steel also significantly different, we should focus on to distinguish the types of steel procurement condensing boilers, regardless of the intensity of the work are recommended to choose high-quality steel material of condensing boilers, such a service life of the boiler to be generally higher than ordinary products, in addition to considerations beyond its material but also the focus of discretion table inside the component materials.

Gas - fired central heating boilers internal corrosion Wet how to care for internal corrosion. Although the gas central heating boiler heating surface deactivated during the boiler's internal and external corrosion at the same time, but the interior is more serious than external corrosion, so the emphasis on oral anti-corrosion were discussed. Gas central heating boiler internal corrosion maintenance wet method This method is not to pan the gas central heating boiler water off when the shutdown, but the gas central heating boiler filled with water to prevent air from entering the pot, filled with water and heating Add other oxygen scavenger, inhibitor or deactivator agents in the boiler, the metal surface to form a carbon protective film to prevent heating surface is not oxidized, so as to achieve a preservative. 1, the internal gas central heating boilers alkali corrosion wet method filled gas concentration within a concentration of lye heating boiler, and keeping the pH at 10 or more. Specific practices are as follows: to remove scale and sediment, to ensure the valves close, operation of the system connected to the piping installation blind plate. The highest position of the gas central heating boiler can be installed - a small box lye to ensure complementary loss when lye lye. The alkali agent used is sodium carbonate, sodium hydroxide, trisodium phosphate, or a mixture. Preparation of soft water should be used, not use raw water. Agent in an amount of: water was added sodium carbonate per tonne pot 20kg; NaOH per tonne pot of water was added 5-6kg; Na3PO4 pot by adding water per ton of 10-12kg. Through a dedicated pump lye into the pot, until the water coming out from the air valve, and to ensure that the pot pressure greater than atmospheric pressure. Initial protection should be strengthened Tightness checks should be monitored once a month after the normal concentration of NaOH. When the alkali concentration is less than 5% of implant concentration, should fill base. 2, the internal gas central heating boiler corrosion wet method This method is hydrazine hydrazine H2N2 full concentration and ammonia NH3 in the gas mixture within the heating boiler. Corrosion is the use of hydrazine, with a strong further removal of the water of oxygen, i.e. N2H4O2 → N22H2O, the cathode polarization. While alkaline with ammonia in an aqueous solution, increase the pH of the metal surface passivation, resulting in anodic polarization, in order to achieve a preservative. Due to toxic hydrazine, use is restricted. 3, the internal gas central heating boilers resist corrosion inhibition method of wet organic organic corrosion inhibitor is water treatment agent multi-functional anti-corrosion, scaling, cleaning and the like. The main components of polyphosphates, organic phosphates, and inorganic bases BTA copper corrosion inhibitor composition. Red brown liquid medicament agent, pH≥13, corrosion mechanism is: water-soluble drug can be hydrolyzed after the polyphosphate anions and positively charged cations with negatively charged polyphosphate anions root metal corrosion in the battery loses electrons and the anode region the Fe2 combined to produce highly insoluble ferric polyphosphate water, and is formed to cover the metal surface of the anode in the anodic polarization regions, hydrolyzed cationic agent captured electrons in the cathode region of the metal, the metal becomes strong affinity and the atoms adsorbed on the metal surface of the cathode region; forming a cathodic polarization. Since these factors are of metal corrosion choke, it plays a role in corrosion. Organic corrosion inhibitors pH≥13, 4-5 tons of water treatment agent according to 1L, the aqueous solution can ensure pH≥10, can effectively prevent acid corrosion caused by CO2 gas, also played a role in corrosion. As organic corrosion inhibitors disable maintenance agent, an agent for the organic phosphorus component also certain ingredients scale and soda boiler system, dissolved iron from dissolution of the scale becomes hard porous loose structure thereof. While enabling the agent to penetrate the protective membrane in scale formation, and destruction of the binding of the metal surface of the scale, so that the scale off.

Ukraine industrial construction quality, customer Ukraine's current visit to our company is very interested in industrial szl series high pressure boiler specification steam boilers. 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).

Why is the pH of the hot water boiler important? In addition, is there a decisive factor in the heating area of ​​the hot water boiler?
