8 to 12 mm BTU per short ton of melted glass using air/fuel. 每短吨玻璃使用空气/燃料提供的热量为8 to 12 mm BTU per 5 to 7 mm BTU per short ton of melted glass using oxy/fuel. 每短吨玻璃使用氧气/燃料提供的热量为5 to 7 mm BTU per
Will save about 35% of energy requirement with oxygen because less heat leaves the furnace exhaust.
将会减少大概35%的能量需求,原因在于在使用氧气后窑炉排烟量降低,能量损失减少。
One gallon of liquid oxygen (LOx) = 115 scf 1加仑液氧=115 scf(标准立方英尺) One gallon of LOx weighs = 9.524 pounds 1加仑液氧重量=9.524磅
One short ton of liquid oxygen (LOx) = 210 gallons 1短吨液氧=210加仑
One short ton of LOx = 24,150 scf 1短吨液氧=24,150 scf
One pound of L Ox = 12.075 scf 1磅液氧=12.075 scf
One kg of LOx = 26.62 scf 1千克液氧=26.62 scf
One kg of LOx = 0.716 m3 1千克液氧=0.713 m3 One ton of LOx = 716 m3 1吨液氧=716 m3 1 scf = 0.0269 nm3
1 标准立方英尺 = 0.0269 标方 1 nm3 = 37.2 scf
1标方=37.2标准立方英尺
1 volume of natural gas (NG) =2.05 times volume of pure oxygen required. 1体积的天然气(NG)=2.05体积的纯氧
1000 scf of natural gas requires 2050 scf of oxygen to completely burn. 1000标准立方英尺天然气需要2050标准立方英尺氧气才能完全燃烧。 When oxygen is supplied from VPSA use ratio of 2.15 times NG for calculating amount.
使用VPSA供氧时使用NG的用量是计算的2.15倍
One kg of oil requires 3.1 kg of LOx for combustion. (Use 3.2 kg O2 / kg Oil). 1千克重油需要3.1千克液氧助燃3.2 kg O2 / kg Oil
One kg of oil requires 2.2196 Nm3 of oxygen gas for combustion. (Use 2.3 Nm3 O2 gas per kg Oil per Combustion Tec). 1千克重油需要2.2196 Nm3氧气助燃

The unit of sales in the USA is in 100 scf units for oxygen. 在美国销售氧气的单位是100 scf
Amount of electric power required to produce 100 scf of O2 is between 1.0 and 1.2 kWh.
生产100 scf的氧气的能耗介于1.0 and 1.2 kWh.
50% to 60% reduction in LPG used on front end burners if changed to oxy/fuel.
如果在前炉将燃烧器更换为纯氧燃烧器,则会减少50% to 60%LPG用量 All forehearths and channels must be wider when using oxy/fuel burners. 所有作业通路和主通路在使用氧气/燃料燃烧器时其宽度需要加长。 No Standard Zircon should be used in oxy/fuel fired furnaces. 在氧气/燃料燃烧的窑炉内不能使用标准锆
Fused alumina, fused grain mullite and AZS are used in the superstructure and crowns of oxy/fuel fired melters. Do not use silica refractory for crowns (however many container furnaces still do use silica crowns).
在氧气/燃料燃烧的熔化部中电熔氧化铝、电熔再烧结莫来石和AZS使用在上部结构和大碹上。不要使用硅砖作为大碹的材料(可是仍有器皿玻璃窑炉的大碹仍然使用硅砖)
VPSA system supply pressure fluctuation is about ± 0.5% while the process prefers about ± 0.25%. The VPSA swings every 20 seconds and pressure and purity will vary.
VPSA系统供气压力波动大约为± 0.5%实际上波动范围为± 0.25%。大约每20秒VPSA切换一次,这时压力和纯度会有变化。
