A staged gas injection system for a flare tip that can discharge waste gas into a combustion zone is provided. The staged gas injection system includes, for example, a first gas injection assembly and a second stage gas injection assembly. The first gas injection assembly is configured to inject a gas (for example steam or a gas other than steam) at a high flow rate and a high pressure into the flare tip or the combustion zone. The second gas injection assembly is configured to inject a gas (for example, steam and/or a gas other than steam) at a low flow rate and a high pressure into the flare tip or the combustion zone. A flare tip including the staged gas injection system is also provided.

本申请公开了一种炉排式垃圾焚烧炉的料层厚度的确定方法及相关装置，涉及焚烧处理技术领域，包括：通过垃圾层压差预测模型，将测量的当前一次风空预器出口压力和当前燃烧1段风门开度这两个准确参数转化为预测燃烧1段垃圾层压差。基于当前燃烧1段垃圾层压差、预测燃烧1段垃圾层压差和预设比例，计算得到炉排式垃圾焚烧炉的燃烧1段料层厚度，基于炉排式垃圾焚烧炉的炉排实时运行速度和炉排总长度，以及炉排式垃圾焚烧炉的预测燃烧1段料层厚度，采用基于欧拉‑拉格朗日混合方法的物料传输算法动态模拟并推算出炉排全程的料层厚度分布，避免在高温、腐蚀环境下料层厚度难以精确测量，准确地确定了炉排式垃圾焚烧炉的料层厚度。

本实用新型公开了废气高温处理装置，涉及催化燃烧炉领域。本实用新型包括换热部、加热部和催化部，所述催化部包括安装框，所述安装框的内侧滑动安装有若干承载网板，所述承载网板上放置有若干催化剂块，所述安装框的两侧且与每层催化剂块位置相对处开设有开槽，本实用新型通过催化部，将挡板全部置于第二滑轨内侧时，废气可畅通进入各层催化剂块，确保高浓度一氧化碳与催化剂充分接触，提高反应效率；同时当废气浓度较低时，挡板切换至第三滑轨可阻隔部分催化剂层，减少无效催化位点损耗和系统气流阻力，使催化剂使用量与处理需求实时匹配，避免冗余反应造成的能耗浪费，显著降低运行成本。

An abatement apparatus and method are disclosed. The abatement apparatus is for treating an effluent stream from a semiconductor processing tool and comprises: a first abatement device configured to receive the effluent stream and operable to run in an active mode to treat the effluent stream; a second abatement device operable to run in an idle mode; and control logic operable, on receipt of an indication of an alarm condition associated with the first abatement device, to run the second abatement device in the active mode. In this way, a first or primary abatement device is provided which treats the effluent stream and a second or back-up abatement device is provided, should the first abatement device malfunction. However, by only causing the second abatement device to operate in the active mode when the first abatement device malfunctions, significant energy savings can be made.

Assemblies, methods, and arrangements include a burner wall configured to support a burner shaft directing a flare to exit the burner shaft and to form a flare tip. The burner wall extends upwards from a base defining a containment area. A protective barrier system includes cylindrical barriers mounted in front of the flare tip in a configuration including rows and columns. The cylindrical barriers form a wind barrier for the flare tip. The wind barrier redirects wind that blows towards the flare tip to prevent the flare tip from being extinguished.

本实用新型适用于危险废物处理设备技术领域，尤其涉及一种配重式危废焚烧系统紧急泄压装置，包括泄压壳体，所述泄压壳体的表面连接有支撑立座，且支撑立座的表面设置有轴套，所述轴套的内部安装有旋转轴杆，且旋转轴杆的外侧套接有翻转块。本实用新型通过翻转块与配重式封板的配合，实现了在系统超压时依靠内部压力推动配重自动开启泄压的功能，结构简洁，无需外部动力驱动。旋转轴杆与轴套的配合提升了启闭稳定性，旋转套筒的设置进一步减小摩擦阻力，使动作更加灵敏可靠。
