Thermal Reactor
The major part of an SRU is the reactor where the reduction of the sulfur takes place. The lining of the SRU must withstand very reducing conditions. This requires refractory materials that have low iron and silica contents. VESUVIUS offers several materials that work well in these conditions:

Combustion Chamber Back up	HR™ insulating bricks VES- 28 & 30 insulating firebrick LITE WATE® medium weight insulating castables
Combustion Chamber	SPARTAN™extra high alumina bricks ANDALU high alumina bricks BHA high alumina high quality mullite bricks CERGUN™ extra high alumina, low iron, low silica gunning materials
Checker Wall
Burner Throat	SPARTAN™ extra high alumina bricks ANDALU high alumina bricks BHA high alumina high quality mullite bricks CERGUN™ extra high alumina, low iron, low silica gunning materials CERCAST™ extra high alumina castables RAM® phosphate bonded extra high alumina refractory plastics
