    Presently used modern techniques to control instead of the
    traditional control techniques for many industrial applications virtually or
    theoretically. In this paper, a Fuzzy logic has been applied to control the
    important variable of steam generator i.e., drum level. It was used simulation
    of Fuzzy system in MATLAB program. The results showed that the adoption
    of control technique that based on Fuzzy logic have a high response to
    indicate the control signals and thus can be depended as an active control
    system for selecting a right decisions compared with traditional systems. A
    very common control problem, and one used in many examples elsewhere, is
    that of controlling the level in a boiler drum. Many industrial plants have
    boilers for generating process steam, and of course boilers are central to
    thermal power generation. The boiler drum is where water and steam are
    separated. Controlling its level is critical – if the level becomes too low, the
    boiler can run dry resulting in mechanical damage of the drum and boiler
    piping. If the level becomes too high, water can be carried over into the steam
    pipe work, possibly damaging downstream equipment. Steam boiler provides
    appropriate quality and quantity of steam to the turbine for power
    generation. In drum type boiler, water and steam flow in the drum is
    controlled in such a way that the water level in the drum is maintained fairly
    at a preset value. While very low water level in the drum may lead to
    starvation and explosion of boiler, too high level may cause carryover of
    water particle and damages the superheaters.
