在使燃料能完全燃燒的情況下希望空氣過剩系數(shù)越低越好。但過低可能造成燃燒不完全，而過高將增加了爐內(nèi)空氣量，降低爐子的熱效率，對于強(qiáng)制通風(fēng)或引風(fēng)，還將增加動(dòng)力消耗，煙氣中的氧含量過多也將增加對爐管和其他部件的損失。

It is hoped that the higher the air surplus coefficient, the better the fuel can be completely burned. But too low may cause incomplete combustion, and too high will increase the volume of air in the furnace and reduce the thermal efficiency of the furnace. For forced ventilation or induced draught, it will also increase power cumption and excessive oxygen content in the flue gas will also increase the loss of furnace tubes and other components.

靠爐底或水冷金屬梁的上升、前進(jìn)、下降、后退的動(dòng)作把料坯一步一步地移送前進(jìn)的連續(xù)加熱爐。爐子有固定爐底和步進(jìn)爐底，或者有固定梁和步進(jìn)梁。

Depending on the action of rising, advancing, falling and backing of the furnace bottom or the water-cooled metal beam, the material is transferred to the continuous reheating furnace step by step. The furnace has fixed furnace bottom and walking furnace bottom, or there are fixed beam and walking beam.

蓄熱式加熱爐的傳導(dǎo)傳熱：傳導(dǎo)傳熱是溫度不同的物體直接接觸（或物體存在溫差）由于自由電子的運(yùn)動(dòng)（對于鋼材）或分子的運(yùn)動(dòng)（對于爐氣）而發(fā)生的熱交換現(xiàn)象，此種傳熱發(fā)生在鋼材表面及內(nèi)部和鋼材及爐底之間。

Conduction of conduction in a regenerative heating furnace: conduction heat transfer is the direct contact of a different temperature (or the existence of a temperature difference between a body) due to the movement of free electr (for steel) or the movement of molecules (for furnace gas), which occurs between the surface and inside of the steel and between the steel and the bottom of the furnace.
