摘要
引言油页岩是一种富含有机质、具有微细层理、可燃烧的细粒沉积岩,油页岩作为能源资源,既可以干馏炼油也可以燃烧发电。油页岩储量丰富,截至2005年底。
In this paper,a model of technological process is to be constructed for Huadian-type oil shale retorting system using Aspen Plus software,and the physical parameters in the model came from oil shale samples of Gonglangtou mine in Jilin province.The overall thermal efficiency and power consumption of the main auxiliary device of this system were analyzed by calculating the mass balance and thermal balance of the simulated oil shale retorting system and by simulating different heating temperature conditions of two-stage heater.The results show increase of heating temperature for semi-coke combustion furnace can reduce consumption of fuel gas in gas combustion furnace.Furthermore,rise of heating temperature for gas combustion furnace can cut down flow of hot circulating gas and reduce loss of condensation heat for retorting gas and oil vapor.So,the overall thermal efficiency of whole retorting system can be improved by simultaneous increase of heating temperature in the two-stage combustion furnace,and its economic benefit can be enhanced by increase of foreign supply amount of gas and semicoke.
