Abstract
OdElINg Of WATEr BOIlErS IN fuEl CONTAMINATEd fluId fuElS The use of biogas is one of the most promising directions for the development of Ukraine’s energy sector, but the replacement of natural gas with biogas causes a number of problems with the operation of heat generating equipment. The main problem is the fluctuations in the composition of the combustion gas. Due to the different composition of gas, there are significant fluctuations in air flow and, as a consequence, varying properties of the gas path and heat transfer processes. The influence of changes in fuel composition, which is fed to the furnace unit on the power of a water heating boiler, is considered. To achieve this goal, a mathematical model for combustion of gaseous fuels has been improved by taking into account the nonlinear dependence of the amount of heat supplied to the furnace device and taking into account the change in the heat transfer conditions at significant fluctuation fluctuation fluctuations. Based on the developed simulation model of 3 boilers KVGM-50, dynamic characteristics are analyzed in the form of acceleration curves obtained when disturbed by the calorific value of fuel.
