Abstract
The use of biogas is one of the most promising directions for the development of the Ukrainian energy sector, but the replacement of natural gas with biogas causes a number of problems in the operation of heat generating equipment. The main problem is the fluctuations in the composition of the gas going to combustion. Because of the different composition of the gas, there are significant fluctuations in airflow and, as a consequence, the properties of the gas-air path and heat-exchange processes change. The influence of the change in the composition of the fuel supplied to the combustion device on the power of the boiler is considered. To achieve this goal, the mathematical model of burning gaseous fuels has been improved by taking into account the nonlinear dependence of the amount of heat supplied to the furnace and taking into account changes in heat transfer conditions with significant flue gas flow fluctuations. Based on the developed simulation model of 3 boilers KVGM-50, dynamic characteristics in the form of acceleration curves obtained when fuel calorific value is excited are analyzed.
