【摘要】 <正> 一、系统及其组成 在炼油厂中采用燃气轮机-加热炉联合系统,可实现热电联供以有效地节能。这种联合系统有多种,按加热炉的型式可分为两类。一类是纯对流型,它将燃气轮机排气引至加热炉中加热介质,当排气热量不足时,可在排气管道上加装烟道补燃器,提高进入加热炉的烟气温度,使热量足以加热介质。该系统方案见图1。另一类是辐更多还原

【Abstract】 The mathematical model for the optimal design of systems integrated gas turbine with heater in refineries is provided in this paper. The model takes the net present value of the system as its optimization object in the whole calculating term, it can maximize the total economic benefit for the system. The results of examples calculated with the applied software are reasonable.更多还原
