The main stages in choosing the optimal technology for thermal treatment of MSW (municipal solid wastes) at the stage of feasibility study are discussed. The analysis of the influence of the fuel component on the structure of the WTE plant is carried out. Recommendations have been developed for choosing the optimal energy structure of a WTE plant, ash and slag management schemes, and thermal utilization technologies that are most suitable for the location of the facility. A study was conducted on the influence of the selected structure of the energy complex on the decision to choose a gas treatment system. A comparison of criteria for choosing the structure of the energy complex at the MSW in comparison with the energy thermal power plant (TPP) is made. Due to the economic and environmental problems that appear during the construction of WTE plants, when it comes to waste scheme for cities and regions, it is recommended to use a scheme with the maximum use of secondary raw materials from waste and thermal treatment only of residues that are not subject to recycling, from which the fractions containing the largest amount of pollutants (RDF fuel) are extracted. The technology using deep recovery of secondary raw materials will simplify the structure of WTE plant, reduce capital and operating costs, and most importantly reduce emissions of harmful substances into the atmosphere with flue gases, ash and slag.
Abstract. In the absence of an effective technological possibility for the storage of electricity in industrial volumes, consumption and production of electrical energy are carried out simultaneously. The ability to generate cover the unevenness of the daily schedule of consumption provides a balance of power system parts, leads to the minimization of network infrastructure costs. This article represents the analysis of the results for balancing certain parts of the UPS Russia, based on the methodological approach described below. Volume of "basic" electrical energy consumption specifies requirements for the structure of generating capacity. Reducing the share of "basic" consumers, including by the construction of its own "base" generation, leads either to an increase in the depth of discharge of generating capacities in the power system, or to the necessary shutdowns of generating equipment at night. Performed calculations showed non-optimal placement of the "base" generation in the Russian Federation. The proposed method allows you to determine the presence and absence of the adjustment range in the power system as a whole or in its individual parts, avoid errors in the placement of generating capacity in the Russian Federation, including nuclear power plants, heat supply units, "green" generation, optimize the cost for the construction of the network infrastructure.
Given the climatic and geographical conditions of the Russian Federation, the development of cogeneration should become the main line of measures aimed at increasing the energy efficiency and reducing greenhouse gas emissions in the country. However, the implementation of programs for development of renewable energy sources (RES) and nuclear power plants (NPP) entails risks of decreasing the amount of combined generation of electricity and heat by combined heat and power plants (CHPP) in the daily load curve base part. The current state of the wholesale market of electric power is characterized by critical conditions for the existing CHPPs in the first price zone of the wholesale market. The electric power cost formed from competitive power bid (CPB) results is such that the incomes earned by heat generating facilities are insufficient for fully covering the costs of their overhauls and modernization of their equipment. The “old” heat generation facilities, including CHPPs, subsidize the development of combined cycle power plants (CCPPs), RES, hydroelectric power plants (HPPs), and NPPs. The Russian Federation energy system development projects must be elaborated taking into account the results from a multivariate analysis of operational, technical, technological, economic, environmental, and social aspects. The heat supply schemes for cities and municipalities are developed subject to ensuring the preset level of reliability with minimizing its cost for the end customer. The minimum cost of heat supply can only be achieved for the optimal structure of heat and electricity generation capacities. This structure must incorporate equipment able to operate in the base, semi-peak, and peak parts of the daily electric load curve, and provide a power margin for passing seasonal maximums in the consumption of electricity and heat. The main milestones of the establishment and evolution of the energy system of Russia are considered. The main trends are shown along with the problems that have arisen in the operation of cogeneration power facilities in connection with the influence of new energy sources. The experience gained in leading foreign countries that have introduced RES is analyzed, and the influence of these sources on the power system balance is studied. The prospects of using combined electricity and heat generating facilities represented by highly maneuverable small- and medium-capacity gas turbine-based CHPPs in the semi-peak and peak parts of the daily electric load curve are analyzed.
