This burner has a load capacity of 5xlOS Btu/hr. The burner is inserted into the front end of the barrel and can be moved in and out to give the desired flame configuration over the bed. Natural gas is the primary fuel. The secondary burner or afterburner is located in the upper region of the elbow section and is used to ensure the destruction of all organic materials that may be present in the exhaust gases. This burner is also fired on natural gas and has a load capability of 1.5xlOS Btulhr. -9- |
