1) Internal Heating
Method :
Jobs such as Horton Sphere, Mounded Bullet, Thin Wall Tank, LPG Bullet,
Columns,
Pressure Vessel, Penstock can be heated by internal heating method using Gas,
Oil fired burner system. Other jobs, which required Refractory Dry
out and Coating
Curing, can also be performed using internal heating method.
