What should I do with the tap water for the boiler?You don t need to add anything

The boiler can produce qualified steam and hot water, but for the safe production of the boiler, the boiler water must also be treated in time.

I. Purpose of Processing.

There are impurities in the boiler water, which will make the boiler scale and corrode, which will cause harm to the boiler. Ensure good steam and save energy.

Two: the steps of processing.

The treatment of boiler water generally has four parts: make-up water, condensate, deoxygenation and ammonia addition of feedwater, and dosing treatment in the boiler.

Three: recharge water treatment.

According to the different uses and the degree of condensate, the amount of recharge changes accordingly, generally according to the steps of pretreatment, softening and desalination.

Four: condensate treatment.

In order to prevent contamination, the condensate also needs to be treated, in combination with the amount of water and the boiler parameters and furnace type, as well as the contamination situation.

5. Deoxygenation measures for boiler water.

Dissolved oxygen in boiler water.

will allow the metal to corrode, in addition to the make-up water and condensate.

Deoxygenation is required, which is divided into hot gas, vacuum, and chemical deoxygenation.

Six: boiler water ammonia measures.

In order to increase the pH value of the water and prevent the metal parts from being corroded by acids, ammonia and organic amines need to be added to the deoxygenated water.

Seven: add medicine to the pot.

Finally, to prevent the formation of limescale, trisodium phosphate needs to be added to the pot.

and other chemicals that turn magazines into sludge that can be discharged.

The first is purification. Second, it is best to do ion exchange softening, and if it doesn't work, antiscalants are generally added.

To improve the quality of hard water, alum is generally added and then filtered.

In this way, the treated water becomes softer and less prone to limescale.

What should I do with the tap water for the boiler?You don't need to add anything

The boiler make-up water needs to be filtered and re-entered into the boiler, and the water quality and steam quality of the boiler and the safe and economical operation of the boiler are extremely important. 1. Boiler water filtration pretreatmentWhen the raw water is surface water, the purpose of pretreatment is to remove suspended solids, colloidal matter and organic matter in the water. Pretreatment filtration equipment is installed, and the raw water is filtered into clean water through water treatment filter materials such as quartz sand and activated carbon.

When the state is sent to the tap water as the boiler make-up water, the pretreatment of the raw water can be omitted, and only the subsequent filtration can be carried out. 2. The resin of the boiler softened water treatment softened water equipment will reduce the calcium and magnesium ions in the hard water to prevent the scale of the inner wall of the boiler tube. For some industrial boilers, this treatment is usually sufficient, although the salt content of the feed water is not necessarily significantly reduced.

3. With the continuous improvement of boiler parameters and the emergence of direct flow boilers, it is required to remove all the salt in the boiler feed water, and the method of boiler water desalination is required. Reverse osmosis equipment is a pure water treatment technology, through the reverse osmosis element to improve the purity of water quality, remove impurities and salts contained in the water, the pure water we drink daily is envied by the reverse osmosis equipment, the water quality is clear. After the filtration of reverse osmosis equipment, the higher concentration of water will become low concentration of water, and the reverse osmosis membrane can isolate all the impurities mixed into the water such as industrial pollutants, heavy metals, bacteria, viruses, etc., so as to meet the physical and chemical indicators and health standards stipulated in drinking water.

Tap water for household heating boilers, you don't need to add anything, and there will be a peculiar smell if you add any antiscaling agent or scale inhibitor.

Whether it is a natural gas boiler or a hot water boiler, in the operation of the boiler, the water needs to be treated, and when the water quality is treated, professional personnel are needed to deal with it. Water treatment is mainly to remove impurities, metal substances and oxygen content in the water, and the potential safety hazards of pipe bursting due to the structure of the boiler during operation. Hope it helps.

Summary. Hello, gas boilers need water treatment.

Hello, gas boilers need water treatment.

The purpose of gas boiler water treatment is to remove calcium and magnesium that are easy to scale in the gas boiler, reduce the degree of fouling resistance of the gas boiler, ensure the heat exchange effect of the gas boiler, and improve the thermal efficiency.

As a pressure-bearing special thermal energy equipment, if the scale reaches a certain scale, it will bury a lot of hidden dangers for the safety of the boiler, so the gas boiler must treat the water quality for the boiler in order to ensure the normal and efficient operation, and meet the requirements of the industry to use the liquid carefully, and at the same time, it is necessary to regularly do a good job in water quality testing to prevent calcium and magnesium ions from exceeding the standard. Filial piety jujube.

The ultimate goal of boiler water treatment is to obtain qualified demineralized water. There are two ways of desalination, namely ion exchanger desalination and reverse osmosis.

Steam boiler softened water index: hardness less than or equal to, alkalinity 6-24; Hot water boiler softened water index: hardness less than or equal to, alkalinity 6-24.

Your index has high hardness and low alkalinity, you should check the resin tank, whether the resin is effective, and then have a correction of the water output. Add alkali to the softened water tank to improve the alkalinity index.

Now the boiler water treatment is easier to do, and the products are: boiler anti-scale descaler, water softener, safety descaler, operation descaler, corrosion inhibitor and so on. The results are very good.

The treatment of make-up water in industrial boilers is generally based on sodium ion exchange softening, because the use of this water treatment method is simple and easy, and the ultimate goal of boiler water treatment is to obtain qualified demineralized water. There are two ways of desalination, namely ion exchanger desalination and reverse osmosis.

Water treatment in the boiler is an important part of ensuring the safety of boiler operation and improving the efficiency of thermal energy utilization. The following are the steps and methods of general boiler furnace water treatment:

Water quality test: First of all, the water quality in the boiler furnace needs to be tested, including pH value, dissolved oxygen, hardness, alkalinity, total alkalinity, chloride ion content and other indicators. These test results will provide the basis for subsequent water treatment programs.

Water Replenishment System: Ensure that the water quality of the water replenishment system meets the requirements and avoid introducing harmful ions or substances into the boiler. Equipment such as reverse osmosis membranes and ion exchangers can be used to pre-treat the make-up water to remove suspended solids, dissolved solids, and dissolved gases.

Oxygen removal: Remove dissolved oxygen in the water in the boiler by deaeration equipment or chemical deoxidizer to prevent oxygen corrosion. Commonly used deoxidation methods include mechanical deaeration and chemical deoxygenation.

Corrosion inhibitor addition: Corrosion inhibitors are added to the boiler to reduce corrosion on metal surfaces. Corrosion inhibitors can form a protective film that reduces the chemical reaction between metal and water.

Cleaning and blowdown: Regularly clean and drain the boiler to remove sediment and dirt from the boiler. This can be done by methods such as chemical cleaners, mechanical brushing, or rinsing.

pH Regulation: According to the water quality test results, the pH value of the water in the boiler furnace is appropriately adjusted, usually within the appropriate range, to prevent the occurrence of acid or alkali corrosion.

Control water level and concentration: According to the boiler design requirements and operating status, control the water level and concentration in the boiler to ensure the safe operation of the boiler and the efficiency of thermal energy utilization.

Regular inspection and maintenance: Regularly inspect and maintain the water in the boiler furnace, including checking the water quality, cleaning the equipment, replacing the chemical agent, etc. Detect and deal with problems in time to prevent boiler failure and damage.

The above steps and methods are for reference only, and the actual boiler water treatment scheme needs to be specifically designed and adjusted according to the boiler type, working conditions and water quality characteristics. It is recommended to consult a professional boiler engineer or water treatment expert when carrying out boiler furnace water treatment to ensure the treatment effect and the safe operation of the boiler.

Boiler requirements for feed water:

1. The boiler feed water must be chemically treated demineralized water.

2. The pressure and temperature of the boiler feed water must reach the specified value.

3. Boiler feed water quality standard requirements: hardness, dissolved oxygen, pH value, oil content, carbon dioxide content, salt content, hydrazine content, copper content, iron content must be qualified, and the water quality must be clear.

The boiler system of the power plant has a special boiler feed water system, which is generally gathered in the centralized control center. Oxygen is the main corrosive substance of the feed water system and boiler, the oxygen in the feed water should be quickly removed, otherwise it will corrode the components of the boiler feed water system, and the corrosive substance - iron oxide will enter the boiler, deposit or attach to the boiler tube wall and heating surface, forming iron scale with poor heat transfer that is difficult to melt, and the corrosion will cause pits on the inner wall of the pipeline, and the force coefficient of resistance will increase.

The feed water of the boiler must be softened water, in line with the safety standards of boiler operation, and try to avoid the direct use of tap water without treatment, because the tap water is not treated, which is easy to cause scaling, which will cause the following effects on the boiler in the process of operation

The accumulation of scale will reduce heat absorption, reduce boiler thermal efficiency, waste fuel, and thus increase boiler operating costs.

The scale has poor thermal conductivity, and the scale adheres to the pot plate or steel pipe, resulting in the heat cannot be transmitted, resulting in local overheating, and in serious cases, there is a swelling phenomenon, and even the boiler is in.
