I-heater yepayipi iwuhlobo lwemishini yokonga amandla eshisa kuqala into. I-heater yepayipi ingahlukaniswa ibe izindlela ezimbili: enye iwukusebenzisa uhlobo lwe-flange lwe-tubular heater element yokushisa kagesi ngaphakathi kwe-heater yepayipi ukushisisa uwoyela we-conduction kubhantshi le-reactor ku-heater yepayipi, futhi udlulisele amandla okushisa ku-heater yepayipi izinto zokusetshenziswa zamakhemikhali ku-reactor ngaphakathi kwe-heater yepayipi Enye indlela iwukufaka izinto zokushisisa zikagesi eziyishubhu ku-heater yamashubhu ngokuqondile kwi-reactor ku-heater tubular noma ukusabalalisa ngokulinganayo amashubhu okushisa kagesi azungeze udonga lwe-heater tubular.
