Description
Technical Field
The invention relates to the technical field of glass processing, in particular to a combustion enhancing system of a glass kiln.
Background
Energy conservation and environmental protection of glass kilns are always very concerned subjects, and with the great promotion of national energy conservation and emission reduction and coal-to-gas work, domestic glass factories often utilize centrifugal fans to send air in a normal temperature state into air-conditioners of branch flues of various small furnaces to participate in combustion in the furnaces.
However, since the oxygen content in the air is only 21% and the rest is mostly nitrogen, in order to make the fuel burn sufficiently, enough air needs to be introduced to prevent the waste gas from generating more nitrogen oxide pollutants, and since nitrogen does not participate in combustion in the furnace, a large amount of heat is taken away when nitrogen is discharged as waste gas along with each system reversal in the production process, so that the energy utilization rate of the fuel is low, and the consumption of the fuel is increased.
At present, hydrogen and nitrogen are used as protective gases in a float glass factory to protect the internal gas environment of a tin bath and effectively reduce tin consumption, and the float glass factory can generate waste gas with partial oxygen in the processes of hydrogen production and nitrogen production, and the waste gas is often directly discharged without utilization.
