Optimization of Thermal Calculation Topology Model for Garbage Incinerator
A multi region thermal calculation topology model is proposed to address the complex heat transfer phenomenon in garbage incinerators,and thermal calculation verification is carried out in an 850 t/h garbage power plant.The results show that the smoke temperature error calculated by the topology model is less than 5℃,which is smaller than the ones obtained by the traditional Gurvich zero dimensional model and three zone model;an increase in calorific value and heat load will increase the flue gas temperature,but the flue gas temperature at the inlet of the high-temperature superheater remains below 580℃,within the design range of flue gas temperature;the establishment of partition model can further optimize the accuracy error of temperature field inside the boiler,and provide a theoretical basis for the design and parameter optimization of garbage incinerators.
