The steam sampling cooler is suitable for sampling media such as liquids and vapors with high temperatures. The steam sampling cooler adopts a spiral tube (commonly known as a serpentine coil) surface cooling structure. The sampling tubes are all made of high-quality stainless steel tubes that are durable, corrosion-resistant, and non polluting for collecting samples, avoiding contamination by metal corrosion substances in the tubes during the sampling process. The soda sampling cooler has the advantages of compact structure, high heat transfer rate, convenient cleaning, and long use.

The steam water sampler is mainly used in the boiler and its thermal system of thermal power plants, including boiler water sampling cooling, feedwater sampling cooling, steam sampling cooling, deoxygenated water sampling cooling, condensate sampling cooling, and drainage sampling cooling. According to the division and collection of sample collection, East Power Equipment provides two types of sampling coolers: a single sampling cooler and a functional steam and water sampling cooler. The functional steam and water sampling cooler (also known as the combined steam and water sampling cooler) can simultaneously sample steam, boiler water, feedwater, and deoxygenated effluent.

The steam sampling cooler is used for cooling steam and water samples in boiler rooms or power plants. Most water in boilers and thermal systems has a high temperature, which is not convenient for sampling and measurement. Therefore, cooling should be carried out during sampling. Therefore, the sample should be introduced into the sampling cooler for cooling. The steam sampling cooler generally requires a flow rate of 500-700mL/min, and the sample can be cooled to below 30-40 degrees Celsius, meeting the standard of DL/T 457-91 in the power industry of the Republic of China

Types of steam and water sampling coolers

1. Sampling of boiler water - usually taken from the continuous discharge pipe of the steam drum and then led to the cooler. Sampling - should be placed as close as possible to the outlet of the discharge pipe leading out of the steam drum, and as close as possible to one of the discharge valves behind the leading out of the steam drum.

2. Sampling of Water Supply The sampling of water supply is usually set after the water pump, on the high-pressure water supply pipe of the economizer, and should be connected to a small pipe on the vertical pipeline of the water supply pipe, from which the water sample is led to the sampling cooler. The sampling pipe for water supply should be located in a position that is sufficiently uniform after adding medication to the water supply.

3. Sampling of condensate: The sampling of condensate is generally located on the condensate pipeline at the outlet of the condensate pump, not at the inlet of the condensate pump, as the pressure at the inlet of the condensate pump is greater than atmospheric pressure.

4. Sampling of hydrophobic water - usually in the hydrophobic tank - sampling. Sampling - set at a distance of about 300mm from the bottom of the drainage tank.

5. Steam sample - pass through the sampling cooler to condense it into water. The steam sampler - steam flow rate - is generally 20-30kg/h. The requirements for the sample outlet duct and cooler are the same as for water sampling.

Steam sampling cooling device

The steam sampling cooler is used for cooling steam and water testing samples in boiler rooms or power plants, such as steam testing samples, boiler water testing samples, and deaerator effluent testing samples.

The three function sampling cooler can simultaneously sample steam, boiler water, and deoxygenated water. It has compact structure, high heat transfer rate, convenient cleaning, and long usage, and is used for small-scale heating and heat exchange in departments such as petroleum, chemical, light industry, and power. The cooler can also serve as a self sealing cooler for oil pumps.

purpose

The soda sampling cooler is used to cool the high-temperature soda samples for timely analysis, and is used in industries such as power and petrochemicals.

Conclusion---

Water sample collection is an important step in ensuring accurate analysis results. The steam water sampling cooler uses high-quality stainless steel as a serpentine cooling tube, which belongs to the surface heat exchange cooling structure. It has compact structure, high heat transfer rate, high strength, strong anti-corrosion ability, easy cleaning, and long use. It takes samples of power plant steam, boiler water, deaerator water quality, etc., and monitors the quality of boiler steam in a timely manner. The cooling water volume and the opening of the sampling valve should be adjusted in a timely manner during use, so that the flow rate of the water sample is adjusted between 500-700t/min, and the temperature of the water sample is between 30 ℃ and 40 ℃.

The steam sampling cooler is suitable for safe sampling and cooling of steam power plants and heating equipment for water and steam analysis, measurement of water and steam quality processes. Boilers and thermal systems have high water and steam temperatures, making it difficult to sample and measure. Therefore, cooling should be applied during sampling. The sampled sample should be introduced into the steam sampling cooler for cooling. Generally, it is required to maintain a flow rate of 500-700mL/min, and the sample can be taken below 30-40 degrees Celsius, meeting the standard of DL/T 457-91 in the power industry of the People's Republic of China. The sampling tube should be made of stainless steel, and carbon steel or brass pipes should not be used, During the sampling process, the sampling medium is corroded and contaminated by metal objects in the conduit.

Calculation of cooling area of soda sampling cooler:

1: If the sample flow rate, cooling water temperature, and initial conditions of the sample are known, the required cooling area of the steam water sampling cooler can be obtained from equation (A1):

A=f? 1.0029/3600 Δ TM? U (A1)

Equation - A - required cooling area, m2;

F - Sample flow rate, L/h;

Δ Tm - average temperature difference, ℃;

U - Overall heat exchange coefficient (U=200 for double-layer spiral tubes and immersion coolers).

When the sample is superheated steam, for every 100 ℃ superheat, the cooling area calculated by equation (A1) should be increased by 12.6%.

2: The average temperature difference can be obtained from equation (A2):

Δ Tm=[(t1-T2) - (t2-T1)]/[L (t1-T2)/(t2-T1)] (A2)

Equation- Δ Tm - average temperature difference, ℃;

T1- cooler sample temperature, ℃;

T2- cooler sample temperature, ℃;

T1- cooler - cooling water temperature, ℃;

T2- Cooling water temperature at the outlet of the cooler, ℃.

3: The spiral tube of the cooler can be composed of a group of continuous coils with the required cooling area, or it can be arranged continuously by two or more groups of spiral tubes.

The steam sampling cooler is used for cooling the steam and water laboratory samples in boiler rooms or power plants. Most of the water in boilers and thermal systems has a high temperature, which is not convenient for sampling and measurement. Therefore, cooling should be carried out during sampling. Therefore, the sampled sample should be introduced into the steam sampling cooler for cooling. Generally, it is required to maintain a flow rate of 500-700mL/min, and the sample can be cooled to below 30-40 degrees Celsius, Meet the standard of DL/T 457-91 for the power industry in the Republic of China.
