Combustion control system for coke ovens embedded with auto positioning systems

摘要

A good grade coke produces highest thermal energy and it is highly efficient in hot metal reduction. In order to concentrate the carbon in coke, the coke making process involves carbonisation of coal to high temperature (1100 degrees C) in an oxygen-free atmosphere. There is always a need to efficiently automate the coke oven operations as much as possible. In order to improve the level of control and management of coke oven, the research on intelligent control system is carried out. In modern advanced control system of coke oven, the control scheme of combination of feedback and feed-forward merged with management is widely utilised. The integrated management and control system of coke oven is introduced systematically, including the production plan and scheduling management (dynamic scheduling) and heating control system (mathematical modelling) i.e. evaluating battery temperature, intelligent combustion control system and the pressure control of gas collector of coke oven battery.
