What is the difference between catalytic converters and secondary combustion?
A catalytic converter is a device through which wood smoke is channeled. It lowers the combustion temperature of the gases, allowing them to be consumed at lower firing. Secondary combustion mixes air with the exhaust gases, causing them to re-ignite and burn before going up the chimney. 4. Which is better? Catalytic converters burn more cleanly, but they need to be replaced after a certain number of hours of operation, and they can cost in excess of $150. Regency uses secondary combustion to achieve almost the same low levels of emissions, and our system is guaranteed for as long as you own the appliance. Secondary combustion systems require less maintenance and are more heavy-duty than catalytic converters.
