燃料气的流动速度燃料气的流动速度与火焰的长短有密切关系，在外混式燃烧器中，燃料气流速过大，会引起脱火；在半预混燃烧器中，燃料气流速过小会引起回火。Thereisacloserelatihipbetweentheflowvelocityandflowvelocityofflamefuelgasfuelgasinthelengthoftheoutermixingburner,fuelgasflowrateistoolarge,willcausetheremovaloffire;inthesemipremixedburner,fuelgasflowrateistoo***allwillcausetempering.蓄热式加热炉是通过炉内热交换过程进行的，蓄热式加热炉的炉内热交换过程有三种基本方式，即：对流传热、传导传热、辐射传热。Theregenerativereheatingfurnaceiscarriedoutthroughtheprocessofheatexchangeinthefurnace.Therearethreebasicwaysintheheatexchangeprocessoftheregenerativeheatingfurnace,namely,convectionheattransfer,conductionandheattransfer,andradiationheattransfer.台车式加热炉的组成包括加热炉本体和余热回收系统。余热回收系统中有一个空气预热器,空气预热器是又由非冷凝式空气预热器和冷凝式空气预热器两段组成。Thetrolleyheatingfurnacecistsofaheaterbodyandawasteheatrecoverysystem.Thereisanairpreheaterinthewasteheatrecoverysystem.Theairpreheaterisofanon-condensingairpreheaterandacondensingairpreheater.)
