摘要
Abstract
The effects of insulation thickness,pipe diameter and control mode on energy consumption and economy of saturated steam power generation system were analyzed by using HydroNet software.The results show that the outlet temperature,outlet pressure and the condensate loss of the outer working medium increase with the decrease of the operating load,while the steam parameters at the inlet end of the outer steam pipe network are kept fixed and the insulation method,outer pipe diameter and routing are unchanged.The reduction ratio of the outer heat loss is smaller than that of the load reduction ratio.Proper thickening of pipe network insulation materials can obtain better economic benefits;In the pipe diameter design,it is better to increase the steam pipe diameter appropriately and design at a lower flow rate in the economic flow rate range.In the unit operation control and optimization,the temperature parameter of the outside inlet end is increased when the load is reduced.Different pipe networks have different temperature drop indicators,and the temperature drop range is 0.050～0.122 ℃/m.关键词
