The operation of heat supply deaerators manufactured by Intechservice LLC, installed at Barnaul CHPP-2, in terms of oxygen content in the water after the deaerator, when operating at the design temperature of the supplied water to the deaerator, meets the requirement of clause 4.8.39 of the rules of technical operation of electric power plants and networks of the Russian Federation.

According to the agreement with your organization, in 2013, the deaeration plant in our sulfuric acid workshop was reconstructed using the centrifugal vortex principle of deaeration. During the tests of the deaeration plant equipment, we managed to achieve a flow rate of 260 m3/hour of deaerated water with a residual oxygen content of no more than 0.007 mg/dm3. The actual achieved oxygen concentration at a capacity of 160-170 m3/hour is 0.005 mg/dm3.
The reconstructed deaeration plant has been successfully operated in the sulfuric acid workshop for more than 3 years, and therefore it was decided to carry out its further reconstruction with an increase in productivity to 370 m3/h based on the design and equipment of Intechservice LLC. This project is currently underway.

In 2011, in boiler house No. 39 (KC-12) in Ufa, your company introduced the UDAV-100/18 vacuum deaeration unit with a capacity of 100 tons/hour. During 4 years of operation, the deaerator unit has been operating stably in the load range from 10 to 85 tons/hour. The oxygen content in all operating modes does not exceed the norm and ranges from 10 to 20 micrograms/dm³. No wear or damage was found during routine inspections of the deaerator. It should be noted that to optimize the deaeration process, a BOA deaeration plant control system was implemented at launch, along with a BOA control panel.
To reduce energy costs, pumping groups of heating supply pumps and water supply pumps for the HVO installation are equipped with complete control devices with frequency drives.
During the operation of the BOA-100 deaeration unit, a decrease in oxygen content was achieved from 15,000 micrograms/dm³ in the source (artesian) water to 5 micrograms/dm³in the make-up water with a stable hydraulic mode available range loads of 10-85 m³/hour at the actual temperature of the deaerated water at the entrance to the DCV equal to 59 ° C and the operating pressure in the deaerator is 0.85-0.92 ata. Overload modes were not observed.
The achieved recharge range of 10-85 m³/hour allowed us to create an optimal operating mode map of the boiler house in summer and winter conditions.

In October-November 2013, an atmospheric deaeration plant of Zimin B.A. design, protected by RF patent No. 2494308, was installed and put into operation. The deaeration plant contains: 1. Centrifugal vortex deaerator (DCV) of the first stage of deaeration, 2. Drip deaerator (CD) of the second stage of deaeration, which is a storage tank with two water dispersants located in the steam space of the storage tank, 3. Contact vapor cooler (HVAC), acting as a condenser of water vapor of the vapor and a preliminary stage of deaeration, 4. Intermediate tank (PB) for draining water from HVAC, 5.Pumps for pumping water from PB to DCV. A variant of the scheme of the deaeration plant was used with the supply of 100% deaerated water sequentially through HVAC, through PB, through DCV, through CD and further through feed pumps and consumers of deaerated water.
The deaeration plant is designed to prepare feed water for imported heat recovery boilers for the production of sulfuric acid, which require, according to the regulations, a residual oxygen content in deaerated water of no more than 7 micrograms/liter.
The deaerated water is demineralized water from the Central heating Plant, which has been treated with cation exchange filters, decarbonizers, anion exchange filters and mixed-action filters.
The operation of the deaeration plant in the period from December 2013 to March 29, 2014 was carried out at loads of 155 - 160 t/h with a residual oxygen content in deaerated water of less than 3 micrograms/l. At the same time, the temperature of the demineralized water entering the deaeration was 78 - 82 ° C. In the contact evaporation cooler, the temperature of the water drained from HVAC and PB is barely noticeable, which indicates the practical absence of heat loss with evaporation.
A one-time test of the installation for maximum productivity showed a value of 280 t/h. At the same time, the temperature of the water entering the deaeration was at 60 °C. There was no visible evaporation from HVAC and PB, and the residual oxygen content in the deaerated water did not exceed the required 7 micrograms/liter.
The residual oxygen content is analyzed by a stationary electronic oxygen meter.

Conclusion:

The deaeration plant, developed and installed by Intechservice LLC on the basis of the Zimin B.A. patent, reliably, sustainably and economically meets the needs of the sulfuric acid workshop in deaerated water of appropriate quality over the entire range of production loads.

The deadlines for completing the stages of work under the contract have been met in full.
The installation stage of the above-mentioned equipment is currently being completed. After completion of the commissioning stages and the corresponding tests, JSC TANECO will provide final feedback on the operation of the deaeration plant.

The HCV 1-06.2 vortex gas dynamic separator was installed in March 2011 in the compressor section after the screw oil-filled compressor (standard equipment without integrated air-cooled dryer) with operating parameters: outlet pressure 7.2 bar, capacity 26.1 nm3/min to the air collectors.

To check the efficiency of the HCV 1-06.2 vortex gas dynamic separator, the following devices were installed on the separator outlet pipeline:
1. Flow meter with functions: accounting for instantaneous flow, pressure and temperature
2. Dew point temperature sensor

Readings of the measurements made:
1. The pressure at the outlet of the separator is 7.2 bar (at the outlet pressure of the compressor is 7.2 bar)
2. Flow rate - 26.1 nm3/min
3. Temperature +34 °C (at compressor outlet temperature +35 °C)
4. Dew point temperature +8 °C

Manufacturer's compressed air quality tests according to GOST 9.010-80 (directional compressed air jet 0.25 nm3/min through a 9 mm diameter nozzle from a distance of 50 mm onto clean filtered paper for 10 minutes - no moisture and oil stains and directional compressed air jet 0.25 nm3/min through a 9 mm diameter nozzle from a distance of 50 mm mm on the surface of the mirror for 3 minutes - a matte coating and spots from drops of moisture and oil were absent).

Based on the results of measurements and tests, it was decided to use vortex gas-dynamic separators of this type on the compressor equipment of Samara Stroyfarfor LLC.

To purify low-pressure compressed air from moisture, a vortex gas dynamic separator VGS 1-06.1 was put into trial operation at Intechservice LLC.
The separator was installed on the compressed air supply line to consumers after 2 VK-50E compressors with a capacity of 5.5 m3/min each. Prior to the installation of the separator, the compressed air in the sandblasting and painting areas contained a large amount of moisture (measured at 3 g/m3).
After installing the HCV 1-06.1 vortex gas dynamic separator, the compressed air meets the requirements of GOST 9.010-80 in terms of moisture content, according to the results of measurements - 0.7 g/m3.
Trial operation revealed that the purification of compressed air after the installation of the separator is quite effective, which allowed us to conclude that the HCV 1-06.1 vortex gas-dynamic separator has been purchased for permanent use.

During the trial operation of the VGS 1-06 vortex gas dynamic separators complete with screw oil-filled compressors U-55 and U-57 manufactured by Uralkompressormash, no discrepancies were found with the technical data sheets, and the purification from oils, moisture and impurities was satisfactory. They are easy to install, operate and maintain.

Conclusion on the operation of the HCV moisture and oil separator 1-06.1.

The separator was purchased and installed in May 2009 in the compressed air supply system for the technological needs of the enterprise.
As a result of operation, it was found that the separator ensures the quality of compressed air purification in accordance with GOST 17433-80.
