Smalll box type ammonia cracker for heat treatment application with 30 Nm3/hr fully automatic
Working Principal of Ammonia Cracker Unit
Cracker Unit is a vertical rectangular cross section furnace. It
has ceramic blanket insulation lining on the walls and on the top.
Floor of furnace is refractory bricks lined. In this furnace retort
is suspended form the top. The retort is made of 20% - 25% Chrome /
Nickel seamless tubes. This material is suitable up to 1100° C
temp. and safe for operating temperature for around 850 deg. C.(
maximum). The retort is centrifugal casted having thickness of
around 10 mm. On the side wall of the furnace coil type Ni-chrome
heating elements are provided refractory supports. Temperature of
the furnace box is controlled at 850° C. which in turn gives
catalyst bed temperature inside the tubes of around 800°C.
Temperature controllers are twin point type. Lower temperature set
point shall be at 800° C. to give alarm in case furnace temperature
falls during normal operation. Upper set point would switch on and
switch off heaters automatically to maintain furnace temperature at
850° C. Heating elements are equally distributed through out the
furnace height and all catalyst tubes are uniformly heated on all
sides. Furnaces has ceramic fibers lining and outside furnace wall
temperature shall be maximum 60° C.
