Operating Parameters Setting Method of Sintering Waste Heat Recovery Process Based on Heat Production Optimization

Abstract

Abstract: In order to improve the efficiency of waste heat recovery system within sintering process, this paper introduced the index of boiler’s effective heat production to evaluate the overall efficiency of waste heat power generation system, and proposed an operating parameters optimization method based on this index. First, the BP neural network is applied to predict the index, so that the optimization model for boiler’s effective heat production is constructed. Based on this model, an improved particle swarm optimization is developed, in order to obtain the optimal values of middlepressure steam’s temperature and coolmachine speed, which result in the maximal boiler’s effective heat production. The simulation results show that the above method is able to improve averagely the boiler’s effective heat production of waste heat recovery system about 5%, and increase the efficiency of waste heat power generation.

Key words: sintering process, waste heat recovery, middlepressure steam, heat production, parameter setting
