How to determine the dosage of boiler? What is the dosage of a boiler cooker?

The dosing treatment in the pot is used as a supplementary treatment for boiler make-up water, condensate, and generated return water treatment. Its function is to make the scaling substances brought into the boiler with the feed water react with the added agent to generate suspended particles, which are in a dispersed state, and are added to the boiler blowdown and discharged into the pot through the dosing device, or make it exist in the boiler water in a dissolved state, and will not be deposited on the boiler tube wall, so as to achieve the purpose of scale prevention.

The maximum dosage (calculated at 100% concentration) for the purpose of increasing the pH value of the feed water and preventing corrosion of the feed pipe

qm=(1～2)qv g/h

qv – feed water flow, m3 h

The volume of ammonia added to the pipe (water tank):

v=qm*10-6/cρ，m3/h；

c——The concentration of ammonia in the metering box, generally;

The density of ammonia solution at C g cm3

The boiler has very strict requirements for the quality of feed water and steam, so the dosing device needs to continuously monitor the quality of the furnace water. For the boiler feed water dosing measurement and control device, the automation of the dosing system has been realized, but there is no automatic dispensing equipment, and it is still necessary to manually dispense the drug according to the test results of the steam and water laboratory, so that not only the work intensity is high, but also the ammonia and hydrazide added are highly toxic and volatile substances, which will cause serious harm to the operator and lead to environmental pollution. The following parameters are given for reference in practice:

For details, please refer to it.

The dosage of the boiler is mainly to control the alkalinity of the water in the furnace, which is generally controlled at about 9.

It is determined by the test results of alkalinity.

According to the hardness and evaporation of water, the boiler descaling and antiscaling agent produced by Liuzhou Bluestar Energy Saving Technology Co., Ltd. has the effect of removing old scale and inhibiting the formation of new scale, and at the same time has the effect of corrosion inhibition! Works great, you can try it.

1. The equipment is used as a supplementary treatment for boiler make-up water, condensate, and generation return water treatment. Its function is to make the scaling substances brought into the boiler with the feed water react with the added agent to form suspended particles, which are in a dispersed state.

2. The dosing device is added to the boiler sewage discharge and discharged into the pot, or it is dissolved and exists in the pot water, and will not be deposited on the boiler tube wall, so as to achieve the purpose of scale prevention.

3. The amount of alkali required for feed water during boiler operation:

1. For non-alkaline water.

It can be calculated as follows: x2=(yd-jd +jdgp)m.

2. X2 is the amount of NaOH or Na2C03 that needs to be added to each ton of feed water.

3. The blowdown rate of PL a boiler is 10-2.

4. Hydrazine. Calculation of the required amount: N2H4=C*D*V*1000 W (kg).

1. C--the percentage concentration of the solution to be prepared.

2. d--the specific gravity of the prepared solution (dilute hydrazine solution is desirable.)

3. V--volume of dilute hydrazine solution m3.

4. The percentage concentration of w--concentrated hydrazine is generally 40.

5. Filling method: generally continuous addition.

3. Sodium hydroxide.

and calculation of sodium carbonate dosage:

The amount of alkali required to add water when the water is filled with water in an empty pot: x1=(yd-jd +jd+ jdgmv).

1. In the formula: X1-When the water is on the empty pot, you need to add the amount of NaOH or Na2C03 G.

2. YD - total hardness of feed water.

3. JD-total alkalinity of feed water.

4. JDG - the alkalinity of the pot water to be maintained.

5. V-boiler water capacity.

6. Molar mass of m-alkaline agent.

7. 40g mol with NaOH and 53g mol with Na2C03.

As the name suggests, the boiler dosing device is used as a boiler make-up water, condensate, and a make-up treatment for returning to Huai dispersed water, so we must control the dosage when dosing, so that the lead can ensure the qualification of the furnace water and the normal use of the equipment.

The amount of trembling medicine used in the boiler boiler needs to be determined according to the water capacity of the boiler. In general, the ratio of trisodium phosphate and sodium hydroxide is 2-3%. That is, 3kg of trisodium phosphate per ton of water and 3kg of sodium hydroxide per ton of water.

If the water capacity is three tons, then add 3kg of trisodium phosphate and sodium hydroxide.

Summary. Hello, I am very happy to answer your questions, Xiaoda has helped you find the answer, after investigation, the dosage of the boiler boiler needs to be determined according to the water capacity of the boiler. In general, the ratio of trisodium phosphate and sodium hydroxide is 2-3%.

That is, 3kg of trisodium phosphate per ton of water and 3kg of sodium hydroxide per ton of water. If the water capacity is three tons, then add 3kg of trisodium phosphate and 3kg of sodium hydroxide. , travel during the epidemic, please be sure to do a good job of epidemic protection <>

I hope Xiaoda's reply will help you and I wish you a happy life!

Hello, the dosage of the boiler boiler depends on the size and capacity of the boiler, under normal circumstances, 2-3 grams of medicine are needed per cubic meter of boiler capacity.

Related information: The role of a boiler is to remove impurities and grease that are introduced into the boiler during manufacturing, transportation, installation, or maintenance. The presence of these dirts will not only clog the water pipes and worsen the quality of the steam, but also make the heat transfer poor, and the heating surface is easy to overheat and the liquid will burn out and bury the bad, so it must be removed with a cooking furnace.

Summary. Dear, I'm honored to ask you your question, and the information you found is: What is the dosage of the boiler cooker?

The dosage of the boiler boiler is 100% purity. 2 When there is no trisodium phosphate, anhydrous sodium carbonate (Na:CO3) can be used instead, and the dosage is 1 5 times that of trisodium phosphate.

3 When anhydrous sodium carbonate is used alone for cooking, the dosage is 6kg m3 water. 4. The dosage should be calculated according to the maximum water level.
