摘要
Abstract
An engineering case study of a heating sys-tem integrating deep geothermal energy with gas boiler room was conducted,in which nine heating capacity scenarios were developed through adjustment of boiler output,with operational strategies being evaluated for maximizing geothermal well utilization while minimiz-ing reinjection temperature.Compared with the opera-tion strategy of constant flow of geothermal water with a designed mass flow rate and less strict requirements on reinjection temperature,the utilization rate of geother-mal wells with variable flow rate of geothermal water with a reinjection temperature not exceeding the suit-able reinjection temperature during heating period has decreased,but the reinjection temperature is more rea-sonable.Therefore,it is appropriate to adopt the vari-able flow operation strategy of geothermal water with a reinjection temperature not exceeding the appropriate reinjection temperature during heating period.The utili-zation rate of geothermal wells reaches 98.45％at 0.5 boiler capacity ratio and achieves 100％at ≥1.00 ratio.关键词
