CT9351 KILNS, FURNACES AND PYROMETRY L T P C3 0 0 3AIMThe course is aimed to enable the students to have a thorough knowledge on theequipments involved in firing of a ceramic article and the temperature measurementmethods.OBJECTIVESOn completion of the course the students are expected to Have a thorough knowledge on the different burners used based on the fuel typeand the types of flame produced from burners. Have studied the different types of furnaces and their operation. Have an understanding on the different factors involved in designing a furnace. Have a better knowledge on different types of kilns, their construction andworking. Have a clear understanding on the temperature and heat measurementtechniques in kilns and furnaces.UNIT I BURNERS AND FLAMES 9Burner – classification, atomization, low pressure burner for gaseous fuel, high pressureburner for liquid fuels, advantage & disadvantage of different burners.
