To simulate high air preheat furnaces used in the glass and steel industries, a 2MMBtu/hr (.59 MW) rectangular
furnace of dimensions 4ft (1.2m) wide, by 4ft (1.2m) tall, by 8ft (2.4m) long, is combined with high temperature
ceramic heat exchangers, which can achieve up to 1500F (816C) air preheat. The burner mounting is very
flexible, and several different types of burners can be accomodated. This facility has been validated, by favorably
comparing conventional burner performance tests obtained by manufacturers, to those obtained in this facility. In
addition, this facility has been used to develop and test a high air preheat burner, which reduces NOx by 90%, at
costs comparable to conventional burners. This example shows
the value of using this test facility. Fuels capability includes operation on natural gas, liquified
petroleum gas and liquid distillate fuels.
