Numerous oil wells within Rumaila field contain Electrical Submersible Pumps (ESPs). ESPs are utilised to maximise the oil production from existing wells by providing artificial lift where pressure is low, which helps maintain oil production levels. The number of ESPs installed throughout the Rumaila. Field is growing consistently to sustain oil field production. Due to the remote locations for each of the ESPs the current strategy is to supply power to ESPs using individual diesel engine generators located at each remote ESP well site. This is an inefficient design, as individual diesel engines are resource intensive due to maintenance and frequent diesel filling. The generators are also a source of significant unreliability causing ESP shutdowns/trips resulting in extended downtime. Given the above a Pre-FEED has been carried out considering supplying ESPs using OHTL’s supplying electrical power from EPP to ESPs in Area C. by uses parallel operation of diesel Generators , we could to constrict 124 from 184 and use 60 only ,by this we get high economic gain and technique, in additional that environmental protection by decreasing pollution.

The paper deals with the issues related to the effect of slagging within the steam boilers furnaces and shows the determination results on peat ash fusibility of Kirov region deposits. Fusibility properties of peat ash (temperatures of deformation, sphere, hemisphere and flow) from the four industrial areas (Dymny, Pishchalsky, Karinsky, Gorokhovsky) depending on its chemical composition are presented. Melting temperature of the mineral part of the peat, determined by GOST, is averaged and does not reflect the actual melting temperature of the individual particles in fly ash. The existence of such separate particles having a melting temperature below the average melting temperature of the ash makes it difficult to find the operating temperature of the torch to reach the minimum of the furnace slagging during peat combustion. The comparison of melting characteristics of peat ash with the reference literature data is performed. The initial slagging temperature is calculated depending on the ratio of the acidic and basic oxides in peat ash.

The effect of paper thermal destruction on its luminescence spectra and luminescence excitation spectra in the spectral ranges of 400-550 nm and 250-450 nm, respectively, was studied. It is proposed to use the characteristic changes in the intensity and shape of the luminescence spectra as a criterion for the state of paper insulation of power transformers. On the basis of the analysis performed, it was concluded that when luminescence is excited at a wavelength of 360 nm, none of the main components of the paper can contribute to the recorded luminescence spectra. It is assumed that the resulting luminescence spectra are due to the emission of various impurities that enter the paper during its production.

Determination of thermal regimes of composite cylindrical bodies by analytical methods leads to the appearance of complex characteristic equations, the solution of which is the determination of eigenvalues. The article considers a relatively simple approximate analytical method for determining the eigenvalues of characteristic equations for a two-layer cylindrical body under boundary conditions of the third kind. This method can also be easily used in more complex formulations of heat conduction problems.
