Abstract

The relevance of the transfer of boiler houses from coal to fuel pellets in the territory of the Republic of Mari El, as well as scientific and practical significance with a brief review of the literature on this issue, is substantiated. A comparative analysis of the parameters of coal and fuel pellets is given and the advantages and disadvantages of boilers using these types of fuels are considered. Options for the construction of a new boiler house, the conversion of the boiler house to another type of fuel, as well as the installation of universal boilers are being considered. A comparison of the principles of operation of a boiler house on different types of fuel, as well as the selection of boiler units for them, is given. The results of the evaluation of the efficiency of the boiler house on coal, fuel pellets and combined fuels are presented. During the comparison of economic indicators, it was found that in order to obtain the lowest cost of 1 Gcal of production and transfer of thermal energy, the conversion of the boiler house to fuel pellets is effective. The technical and technological solutions developed during the study can be used in the operation of coal-fired boilers in the Kilemarsky district of the Republic of Mari El
