Application description of vortex steam flowmeter in energy saving and consumption reduction control

Steam flow meter is applied to energy saving and consumption reduction control
Give two simple examples: power generation, heating.
Therefore, steam is always in our hands, both in the industrial field and in the civilian life. The steam comes from a steam boiler. Boilers are inseparable from coal, fuel, gas, natural and energy sources. With the strengthening of the national energy conservation and consumption reduction management, and the continuous improvement of the awareness of energy saving and consumption reduction by various units, enterprises have paid more and more attention to internal cost accounting, saving energy and reducing consumption, and have become the focus.
Among the users we contact, in addition to the application of steam flow meters by production companies, steam metering has been mentioned on the agenda of hotels, schools, business districts, office buildings and other facilities. Of course, the energy saving and consumption reduction of steam boilers is the key point. The environmental monitoring of flue gas in coal-fired boilers and the gas metering of gas boilers cannot be ignored. The focus here is on the flow measurement of steam.
The metering of the main pipeline steam assesses the efficiency of the boiler. The steam consumption of each steam unit is recorded, and the work cost of each unit is recorded. The measurement data of each steam flow meter provides accurate data for the operation control of the boiler.
The gas flow meter guarantees the measurement of the user's steam flow in terms of performance and quality.
Structural features of the steam flow meter:
1. Simple structure and low price. The sensor is actually a 90 degree standard elbow, and there is no flow sensor that is simpler than its structure. With the development of the machining industry and the continuous improvement of industry standardization and standardized management, the standard mechanism used as a sensor elbow is getting better and better, and the price is getting lower and lower;
2, without any additional throttle or insert, can greatly reduce the power consumption of fluid transport in the pipeline, saving energy, especially for those large system, large diameter, low pressure head measurement object is more obvious.
3, the sensor is resistant to wear and is not sensitive to trace wear, so long-term operation can also ensure accuracy.
4, the direct welding method can be used for installation, so that the trouble of running on the spot is completely solved;
5, strong adaptability, high temperature resistance, high pressure resistance, impact resistance, vibration resistance, moisture resistance, dust resistance, wide measuring range, range ratio up to 1:10, for steam, its applicable range is 0-70m / s, It can better meet the requirements of steam flow measurement. The requirements for straight pipe sections are not strict, generally only the first 5D and the last 2D are required, which is far lower than the requirements of other flow measuring devices;
6, high precision, good reproducibility, measurement accuracy of up to 1.0%, reproducibility accuracy of up to 0.02%, after a single installation, no longer need to disassemble, so the installation accuracy can be best guaranteed.
Steam flow meter instrument performance characteristics:
(1), can display instantaneous flow, cumulative flow, temperature, pressure and other parameters;
(2) The compensation model is rich, and the saturation steam and superheated steam density can be compensated in real time.
(3), small flow to fill the volume measurement function. Combined with real-time monitoring and recording function, it effectively prevents tampering.
(4) High-precision bar graph display, real-time trend curve display, historical curve recall;
(5) Provide cumulative daily report, monthly report and annual report.
(6), providing instantaneous flow 4~20mA output function, with RS-485 or RS-232 communication interface.
     Through the use of the site, the majority of users really realized, the effect of steam flow metering on energy saving, small investment, improved management, long-term return, so that users get benefits.
The significance of using a steam flow meter:
1. Know your own unit energy operation situation, and know what you know.
2. According to the amount of steam used, adjust the operating conditions of the boiler to achieve the purpose of energy saving.
3. Provide accurate numerical basis for internal cost accounting.
4. Improve steam utilization rate, master reasonable data, and discover and eliminate waste.
5. Master boiler operating efficiency and make reasonable adjustments to achieve energy saving, cost reduction and profit improvement.
