Abstract: FIELD: composition determining technologies. 
     SUBSTANCE: invention relates to technologies for determining the composition and concentration of products formed during thermostating of lubricants. In the proposed method, a sample of a lubricant of constant volume is tested in the presence of air with stirring at a temperature selected depending on the base of the lubricant and the group of performance properties for a period of time. According to the invention, the thermostating of the lubricant is carried out at least at three temperatures, a sample of the oxidized lubricant is taken at regular intervals, the optical density is determined by photometry, and the graphical dependences of the optical density on the thermostating time are plotted for each temperature. The rate of formation of primary oxidation products is determined from the section of dependence up to the inflection point, and the rate of formation of secondary oxidation products is determined from the section of dependence after the inflection point. Along the inflection point ordinate of the dependence of the optical density on the thermostating time, for each temperature, a horizontal line is drawn characterizing the concentration of primary oxidation products required for the formation of secondary oxidation products, on which several time intervals are arbitrarily selected, from which perpendiculars are drawn until intersection with the linear dependence of the concentration change primary oxidation products. They are extended by this value, and according to these values, a graphical dependence of the optical density is plotted, which characterizes the concentration of converted primary products into secondary ones from the time of thermostating, and the conversion rate is determined. And the effect of the temperature and the basic base of the lubricant on the concentration of products formed during thermostating is determined by the difference in the rates of formation of secondary products and converted primary oxidation products into secondary ones. 
     EFFECT: disclosing the mechanism of formation of thermostating products and determining the effect of temperature and the basic base of the lubricant on the rate of formation of oxidation products and the concentration of primary products required for the onset of formation of secondary oxidation products.

Date Mar. 31, 1983.In a method for reducing the start-up and stabilization period losses, for increasing the usable power and to improve the controllability of a thermal power plant, there are integrated into the power plant's steam cycle pressurized heat storage reservoirs which are charged by feeding them with excess heat produced in the said power plant as, for example, during the start-up and load stabilizing periods or during periods of reduced electrical power production and, when there is an increased demand for heat, the said heat storage reservoirs are discharged by the release of stored heat into the water-steam cycle. Control deviations in the electrical power while the power plant is in full operation are counterbalanced by changes in the charging and discharging streams of the pressurized heat storage reservoirs. In the apparatus for carrying out this method, pressurized heat storage reservoirs are connected, on the water-side, to the condensate system and, on the steam side, to the medium pressure of intermediate superheater network of the steam cycle or also to the power plant's medium pressure or low pressure turbine extraction points.
