Improved installation of gas filtration at thermal power plants in the preparation of fuel for urban energy systems

Abstract

In accordance with the concept of development and modernization of energy, improvement of energy supply systems of LLC Gazprom processing enterprises will be aimed at the creation of highly efficient energy complexes and gas saving through the introduction of new combined units based on gas turbine units (GTU), providing a minimum level of costs. Improving the infrastructure of power equipment of gas processing enterprises, including fuel treatment systems, determines the efficiency of its operation. The improved design of the cyclone filter is proposed for the modernization of the gas filtration line of the fuel treatment system in order to improve the reliability of both the infrastructure and the energy systems and complexes. The device can be used for separation of suspensions at the point of gas preparation of the KS and GDS, including for gas turbine and combined cycle power plants TPP. The results of bench tests of the proposed design of the cyclone filter and numerical studies of the aerodynamic parameters of the cyclone based on the methods of Computational Fluid Dynamics (CFD). The distributions of tangential and axial flow velocities in the annular space of the cyclone are obtained in the field experiment. Similar devices can also be used to increase the degree of purification from fine particles of PM10, PM2,5 atmospheric emissions of energy systems, due to the reduction of the size of the captured particles from the average values for
