中文摘要	An industrial furnace with multiple parallel passes and multiple burners is commonly used in petroleum refineries to heat the preprocessed oil to a specific temperature (the heated oil is piped to the distillation column for fractionation). In order to maintain the furnace running in a safe, stable, and high-efficiency state it is necessary to control the outlet temperatures of the multiple passes to be the same, which is also significant for improving the product quality of the distillation column. Traditional control methods usually have trouble in controlling these temperatures, and some advanced control methods are too complex for convenient use. In this paper, a control technique, called multiple differences control technique (DsCT), is proposed to distribute the oil inlet flowrates such that the outlet temperatures are as identical as possible. The principle of the proposed DsCT is first explained and demonstrated, the system analysis, controller design, and simulation experiments are then presented, and finally the application results to a real-life petroleum refinery furnace are reported. The DsCT technique has the following advantages: it does not need complicated design procedures, the controller structure is simple, it is easy to apply, and it can be canonically applied to furnaces with different number of passes, etc. (c) 2006 Elsevier Ltd.
