Abstract
The ongoing research provides for the development of general technical solutions for the creation of a methane-hydrogen water-heating boiler unit. The advantages of this source of thermal energy over similar units is the reduction in specific carbon dioxide emissions per unit of thermal energy produced, which is relevant for the decarbonization of the Russian heat and power industry. As part of the work, a mathematical model was created for the mixed thermal calculation of a hot water boiler unit (calibration for the furnace and constructive for the convective part) in the Python programming language. The calculation in the model is carried out on the basis of the normative method. Implemented the ability to calculate the conversion of the most popular standard sizes of hot water boilers to another gas composition: KVGM-10, KVGM-20, KVGM-30, KVGM-50, KVGM-100, KVGM-180, PTVM-30, PTVM-50, PTVM-100 and PTVM-180. The result of the calculation of the reconstruction of the convective part is the required area of the heat-receiving surface, which makes it possible to estimate the volume of reconstruction. The paper analyzes the volume of reconstruction of burners RGMG-10, RGMG-20 and RGMG-30 when switching to a methane-hydrogen mixture.
