THERMAL OXIDIZER
The thermal oxidizer is a downwards-fired furnace suitable for studying combustion efficiency of gases including gasification synthesis gas, simulated tail gas, or other industrial waste gas streams. Two natural gas-fired, horizontal opposing burners at the top of the oxidizer provide up to 400,000 Btu/hr (120 kW) of heat input. The gas to be burned is fed into the top of the oxidizing chamber and combustion air is either co-fed with the gas (burner mode) or is fed by providing excess air through the natural gas burners (mixed combustion mode). Oxidizing efficiency is evaluated by measuring the temperature profile along the length of the oxidizer and measuring the product gas for NOx, SOx, CO, hydrocarbons, etc.
