The Method of Selecting Boiler Houses under Technical Re-Equipment in a Mini-CHP

The development of the energy sector is aimed at improving the energy efficiency of heat and electricity. One way is to use cogeneration technologies. A large number of boiler houses created the preconditions for the creation of a mini-CHPP through their technical re-equipment. The purpose of the work is to develop a methodology for selecting and ranking boiler houses for transformation into a mini-CHPP. To achieve the goal, the following tasks were solved: the ef-fects of the formation of a mini-CHP in the energy district were revealed; a system of criteria has been developed that determines the feasibility of transforming a boiler house; a ranking co-efficient was proposed that reflects the potential for improving efficiency; the methodology was tested. The difference of the work is the complexity of the methodology, which takes into ac-count both the advantages of cogeneration technologies and energy balances, as well as individ-ual features of each boiler house. Multi-criteria selection of boiler houses is based on the pur-pose, fuel used, heat output and functions in heat supply systems. The technical condition, pro-spective balances of production and consumption of electricity in the energy district of a mini-CHPP are taken into account. The significance of the results lies in the fact that the proposed methodology makes it possible to increase the validity of decisions when transforming a boiler house into a mini-CHPP. The use of the selection results will lead to an increase in the economic efficiency of the heat supply system
