Nan nasyon yo devlope, la tèmik ki pi efikas selon yon vè jeneral au se de 30% pou 40%. Nan la chin, nonm sa a apeprè pi ba pase 10%. Nan mitan tout chalè pèt nan pwosesis la, ki ap fè vit, nan gaz yo kite kont regenerator yo pou anpil moun nan li. Tanperati gaz sa a se nòmalman nan 500℃ ou dèyè 600 kontab ℃ pou 20% ou dèyè 25% la an antye vè au enèji D'. Gerizon nan kalite sa a tounen yon dezè chalè relativ tanperati ki te al okipe nan tan pase, ki se pa sèlman yon dezè enèji men tou pa bon pou anviwònman an.

In developed nations, the thermal efficiency of a general glass kiln is from 30% to 40%. In China, this number is approximately lower by 10%. Among all heat losses within the process of glass-making, gas leaving the regenerator accounts for the majority of it. Temperature of this gas is normally from 500℃~600 ℃ accounting for 20% ~25% of the entire glass kiln energy input. The recovery of this type of relatively low temperature waste heat has been neglected in the past, which is not only a waste of energy but also harmful to the environment.
