Upper Steam Flare Tip The BTZ-US (upper steam) flare tip incorporates a high-stability pilot and a flame retention system. With a high efficiency, low noise steam injection ring, the flare tip provides smokeless burning with lower noise than traditional steam injection systems. The upper steam injection is mechanically superior in design while providing greater flow at lower steam pressures. Special multiple orifice steam drilling ensures the lowest possible unshielded noise level. Flares larger than 30" may include internal refractory lining. Internal steam injection is also available. Key Features: • Low noise steam ring • Plug welded brackets • Extremely stable pilots • Superior manifold connection • Smokeless burner with lower noise • Mechanically superior design • High stability flame retention ring • Lower pressure drop or higher flow at a given pressure
