Description: Fuel shut-off valves for burner systems are used in: power plants, steel mills, oil refineries, chemical plants and other industrial plants. In thermal power plants, which base their 100% capacity on coal, there is an oil burning system for ignition of the pulverised coal furnace. Generally burners are scanned by ultra-violet or infrared light, which senses presence of flame. If the flame goes out, scanner breaks contact of solenoid valve and activate fuel shut-off valve. These find applications in thermal power plants and in pulverised coal furnaces with main shut-off damper on the burner inlet or coal mill outlet. Brief specifications: medium-pulverised coal; temperature - up to 200°C/390°F; pressure - up to 10 bar/145 psi; valve - Kuhme KSK; actuator - pneumatic or electric; and size - DN 150 to DN 800/6″ to 32″.
