Abstract: Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.

Abstract: Abatement systems are used to remove harmful pollutants resulting from manufacturing processes. Prior art abatement systems can dangerously back-flash due to, for example, changes in gas velocity and if the inlets become constricted due to clogs. To prevent back-flash a sprayer is introduced to an inlet of the abatement system. The sprayer sprays a volume of a cooling liquid, such as water, into the inlet. In the event of a back-flash, the liquid can extinguish the flame, preventing further damage to the abatement system. The sprayed liquid can provide further benefits, such as cooling the incoming, mitigating effects of reactions within the cooling gases, and flushing away solid particles that would otherwise clog the inlet. These further benefits can allow the abatement system to safely handle additional gases and larger volumes of incoming gas.

Abstract: A stream of exhaust gases from the combustion of hydrocarbon-containing fuels with a variable temperature can be produced by dividing the exhaust gases into two separate part-streams, cooling one part-stream and then combining the two part-streams again. The temperature of the exhaust-gas stream which has been combined again can be set to between the temperature of the combustion of the hydrocarbon-containing fuels and the temperature of the cooled exhaust-gas part-stream by corresponding throttling of the two part-streams before they are brought together again. The exhaust-gas stream produced in this way is preferably used for the defined ageing of automotive exhaust catalysts. In this context, it is particularly advantageous that the change in the temperature of the exhaust-gas stream has no influence on its air/fuel ratio.
