氧气/燃气技术
- The oxo-gas technology in Distributor and Forehearth reduces the natural gas energy consumption of 60% compared with air-gas technology, as well greenhouse CO2 gas emission.
- 该技术可将NOx排放降低80%。
- Technology uses separated oxy-gas fluid burners with nozzle mix and eliminates the risk of backfire. The burners, with a special design, are distributed along the distributor and forehearth length ant they have low power for a good thermal homogeneity.
- Oxy-gas technology approaches the combustion in distributor and Forehearth by long experience in combustion technology and solves all the issues. The table resumes the main topics.

烧枪
Glass Service Oxy-Gas burners are specially designed for distributor and forehearth. The main features of those are:
- 每个烧枪功率低
- 功率范围 1.5~5Kw
- 喷嘴积碳少
- 维保和高精度安装支架易于拆卸
- NOx排放低
烧枪可以从工作位置轻松拆卸，并通过校准孔重新安装
推荐正确对齐的烧枪砖和烧枪喷嘴，以确保正确的功能
烧枪软件
建模设计
Burners are designed with large use of CDF software mathematic modelling.
通过数学建模，可以模拟火焰长度和形状以及所有功能参数。
The special burners nozzle design include the oxy cleaning technology.
Low value oxy flow surrounds the burner nozzle and does no allow the contact between the combustion residual and the nozzle steel.
This technology removes the carbon deposit on the nozzle.
烧枪砖设计
烧枪砖是技术的重要组成部分。Glass Service设计的烧枪砖具有特殊尺寸，与火焰形状正确匹配。
氧气-氢气燃烧
氧气-燃气阀组可以轻松应用于通过用氢气替代天然气，来减少排放。Glass Service已经成功地为分配料道和供料道应用测试了低功率的氢气-氧气烧枪。
The natural gas skid technology, with thermal mass flow transmitters and flow control valves, is also suitable for hydrogen use.
Glass Service has already designed hydrogen combustion technology skids and solved related the leakage issues finding materials, fittings, and equipment, making them ready for hydrogen use.
Not only hydrogen alone, but in the Green Transition, a blend of natural gas and hydrogen can also be applied.
分配料道和供料道应用中的氧气-燃气燃烧技术，将是实现二氧化碳零排放的绿色氢气-氧气燃烧的第一步。
供料道和耐火材料
在分配料道和供料道应用中使用氧气-燃气燃烧技术的耐火材料设计需要特别注意 上部结构的材料和形状
Glass Service的经验和设计得到了上部结构和烧枪砖的CFD数学建模的支持
详细的工程和CFD数学建模被应用于 分析火焰与烧枪砖之间的相互作用，以及火焰与上部结构耐火材料之间的相互作用。
设计考虑到：
- 耐火材料的温度限制要求
- 烧枪产生的废物循环
- 玻璃的热均匀性
- 消除玻璃表面的热点
- 中央玻璃流冷却，应用于分配料道和供料道高的出料量
