Abstract
The method of calculating the cost of implementing the system of drying of fuel by gases for reduction of expenses of fuel for the TPP-210A boiler unit is proposed. This method allows to determine changes in the technical parameters of the four options for the use of fuel for the unit: normal fuel, without drying, with drying in a closed system, and with drying in an open system (the last 3 options involve degraded fuel). Processed fuel requirement will decrease by 14 %. Project economic efficiency is 0.3 US dollars/US dollars. The project payback period is 3.33 years. Program (Project) Evaluation and Review Technique (PERT) was used as the data collection methodology. The network schedule of the planning process and determination of its design parameters of the energy-saving project development are built. As an additional method for the collection of primary data to calculate the cost, the primary data collection tool '1C Enterprise' software product was used. • To determine the cost of the project, the methodology for estimating the implementation of the project of the gas fuel drying system based on the determination of capital costs and technological capabilities of technical equipment is improved; • It is proposed to use the method of network planning and management in the system of development of energy-saving projects as it allows to determine the design parameters to increase the efficiency of research activities; • This methodology for estimating the technical and economic calculation of the implementation of the project of the gas fuel drying system for cost reduction may be of interest to industrial enterprises and thermal power plants that use steam boilers.
