2019-7-9 · Q (H).What do you meant by tangential firing with respect to pulverized coal fired boiler? The method of firing used for coal firing in pulverized fuel fired boiler is the tangential firing. In this type of firing four burners are used at the corner to corner to create a fire ball at the center of the furnace.
