Shkulova N. V., Ivanova E. S., Guseinov Y. S.Method of improving the efficiency of the heat exchange equipment of the hot water boiler ТВГ-8М on terms of the long life service
The processes of incrustation are caused by huge amounts of dissolved salts in the heat medium. When being exploited the evaporation of the heat medium leads to the ion concentration in it and reaches its satiation. Further increase of the ion concentration leads to scaling. Heated shielding pipes are subjected to scaling more than any other elements of the heat generator.
Scaling makes the exploitation of the heat boiler more difficult and leads to some negative effects: valve exchange piping is reduced, heating area is overheated, fuel consumption is increased, fan efficiency is reduced, service life of the system is decreased, extra restorations grow in number, and consequently restoration and service
costs are increased.
There are two main methods of descaling: chemical and non-chemical. When the chemical method is applied acid solvents are used for descaling. The nonchemical method is introduced in RD 153-34.1-37.410-00 and it is composed of magnetic, mechanical, hydromechanical, electrohydropulsed and ultrasonic methods.
The non-chemical ultrasonic method of descaling is the most preferable in ecological and economic aspects as it makes it possible to carry out descaling when the heat generating equipment is being exploited without switching it off. This method is widely used in power systems, but it can’t be applied in heat generators with the complicated geometry of shielding pipes.
The ultrasonic method based on acoustic cavitation is the most effective one, because without having close contact with the descaled surface the intensity of ultrasonic field in the liquid is distributed evenly thus making it possible to descale the surfaces with the complicated geometry.
The use of ultrasonic cavitation method in the boilers TVG-8M is considered in this abstract. The acoustic converters (D) connected with the external piping of the heat generator are offered to use. The ultrasonic cavitation method and the scheme of connection of acoustic converters to the external piping of the boiler TVG-8M allow to distribute the cavitation field of descaling in the calorific surface of shielding pipes to its limit and the special design of the node of connection makes it possible to eliminate negative effects of ultrasonic alternating fluctuations to the walls of the pipes of the heat exchanger.
The technological process of descaling of the heat exchanging surfaces of TVG-8M can be carried out in the exploitation as well as in the off-preventive modes.
Applying the acoustic cavitation method of descaling in the internal surface of the heat exchange in the boilers TVG-8M makes it possible to keep the design sizes of the heat generator at the adjusted hydraulic parameters during the whole life service and to make fuel consumption effective due to the lack of scaling on the surfaces of the heat exchange thus providing trouble-free operation of the heat generator.
Zakharov D. Y., Utkina Yu. I.Historical overview of the development of labor law in Russia in the aspect of accounting and investigation of accidents on production
History of labour safety development in Russia is closely related to labour rights in general. In the article history is considered from the imperial period of time and before, the existence of serfage-almost the labour of slaves, did not give a possibility for the development of such notion as labour safety. It is proposed to divide the development of labour right on 6 stages. The modern period can be divided on enumeration and investigation of accidents in 90s and nowadays, as these two stages have definitive differences.
Statistical data about accident rate during oil and gas production reveals the fact that drilling equipment defects and low discipline in workplace are main reasons for accidents in the process of well construction.
