Summary
□ QIYAO-LTG-FGR Series Low NOx Gas Burner can be applied for complicated working conditions;
□ Combined with FGR (flue gas recirculation) technology and within the range of load regulation, it will steadily achieve the NOx emission to be less than 30mg/Nm3;
□ Mainly consists of: Low NOx burner (including ignition lance, flame detection switch etc.), separate blower, fuel gas valve controlled by servo motor, air throttle, FGR throttle, gas safety on/off valve, control cabinet, etc.;
□ Applications: for industrial boilers, heaters and heat conduction oil furnace, etc., which have to meet the demand of low NOx emission and use the civil gas, natural gas as fuel.
□ Single capacity is up to 50MW.
Advantages:
◇ Advanced technologies to be adopted: Gas staged combustion technology, Air staged combustion technology, Flue gas recirculation technology.
◇ Based on the assurance that the gas to be completely burned out, it will steadily achieve the low NOx emission (lower than 30mg/Nm3) within the full range power regulation;
◇ Adopt international advanced gas combustion program control system so as to ensure the burner under safety & reliable operation;
◇ Adopt electronic air/fuel ratio regulation method which is quick & convenient, friendly to man-machine interface, so as to provide a good foundation of maintenance.
