| With the growth of China’s energy demand was rigid, by the ability of domesticresources and environmental protection capacity constraints, bottlenecks of resourceand environmental constraints facing economic and social development is moreprominent, steel companies and pressure, waste heat utilization is an importantinitiative,"second five" plan launched one. In this paper, iron and steel enterprises inthe sintering waste heat power generation system for the study, for the sinteringcharacteristics were sinter cooling process some experimental studies the impact onexports of flue gas parameters and parameter changes annular cooler outlet flue gasparameters of the steam generated disturbances response process parameters studied,and finally adjusting flue gas recirculation system control design and optimizationstudies, three parts are relatively independent but mutually supporting, mainly relatedissues:.1.Sintered ore sensible heat recovery experiment, study material layer thickness,cooling wind speed and air temperature cooling air initially the most controllablefactors were studied under the influence of the temperature of the flue gas outlet inthe three factors, the smoke carries (Exergy) values, and sinter release (Exergy)values and other parameters The variation..2.To establish a dynamic mathematical model of heat recovery boiler singlerefrigerant heat exchanger based lumped parameter method, the use of simulationalgorithms running on the dynamic characteristics of the pressure superheater pilotstudy; established based on the conservation of energy and heat transfer equationsBoiler static mathematical model to study the static properties of steam parameterschanged conditions.3.Proposed sintering flue gas waste heat power generation cycle regulation andcontrol of the parameters of the program, and the sintering characteristics of thewaste heat recovery process targeted to optimize the process parameters have toensure the safety within a reasonable range. |
