Industrial refineries or boilers in Isfahan
Before the fluid enters the boiler pipes and tanks, boiler water is purified. By purifying water, the performance of boilers and their efficiency improves. The steam that is produced from boiler water causes heat transfer in all the facilities of this system. In this article, the leading steam industry, (starting industrial purification and steam boilers in Isfahan) with how to purify boiler or steam boiler water and also You will get acquainted with buying chlorine.
Boiler water
In boilers, water is heated by pipes and tanks and produces high quality steam. The source of heat production can be fossil fuels, electricity or nuclear energy. Heat is transferred by the generated steam in all installations. To this important task, water purification in steam boilers is of great importance. But before water or any other fluid enters the boiler, it is purified. It is important to control the three important factors of PH, water hardness and TDS in the incoming water. With purification, steam boilers will be safe from damage.
If the water treatment of the boiler or steam boiler is not done, the internal parts of the boiler, safety equipment and auxiliary pipes will be scaled. So the thermal power decreases, the efficiency of the boiler decreases and the boiler fails. As a result, in addition to shortening the life of the equipment, the steam production process is damaged.
How to refine the boiler water or boiler boiler
According to factors such as water quality and chemistry, as well as boiler requirements, the types of boiler water purification processes are different. But it generally includes the following steps.
Substitute water: The water that is first received from the source and replaces evaporated water or water that drips from the boiler is called substitute water. This water can be city water, unfiltered water, etc.
Formation of chemical sediment and coagulation: by adding different chemicals to the water tank after large foreign particles from Dissolved, suspended matter and other pollutants are removed. This is done using one or two reactors where the added chemicals combine with fine particles to form heavy particles for settling. Alum and polyaluminum are among the most common coagulating materials.
Filtration and ultrafiltration: This process is done in order to remove suspended particles such as sediments, turbidity and different organic substances from water. Particles with a size of less than one micron are removed with this method. Hardening resin: Hardening resin can remove the hardness caused by compounds such as bicarbonates, sulfates. remove chlorides and nitrates. By using a strong acid cation, it binds to a weak ion such as sodium. The sodium released by the hardening resin combines with hardening ions such as calcium, magnesium and iron.
Alkalization: Alkali removal resins such as sodium chloride reduce the pH of water. Chloride in this strong anionic resin replaces bicarbonate, sulfate and nitrate.
Reverse osmosis and nanofiltration: Most of the harmful impurities that contaminate RO/NF membranes, It is removed by reverse osmosis and nanofiltration. Pollutants are trapped by passing through semi-permeable membranes under water pressure. Bacteria, salts, organic matter, silica and hardness are among the substances that are removed by this process.
Gas removal: the mixture of condensed gas returned to the system is made with purified replacement water and enters the aeration process. Because the presence of oxygen and carbon dioxide in any amount causes corrosion of pipes and boiler equipment. The price of buying chlorine in the market is different according to the type of producing countries.
