Air intake and exhaust piping system for gas-fired regenerative bogie furnace

Abstract

This utility model relates to an air inlet and exhaust piping system for a gas-fired regenerative trolley-type heater. The system includes a furnace body with several regenerative burners mounted on its wall. Each regenerative burner is connected to a reversing valve. Two regenerative burners facing each other on the furnace body form a group. The same-side interfaces of the two reversing valves connected to the two burners in this group are connected to the same connecting pipe; that is, the air side is simultaneously connected to the air inlet pipe, and the exhaust side is simultaneously connected to the exhaust outlet pipe. The air inlet pipes of each group of regenerative burners are connected to the main air inlet pipe via a branch pipe, and the main air inlet pipe is then connected to the main air inlet pipe. Similarly, the exhaust outlet pipes of each group of regenerative burners are connected to the main exhaust pipe via a branch pipe, and the main exhaust pipe is then connected to the main exhaust pipe. This utility model ensures that the air inlet and exhaust pressures at each regenerative burner are relatively equal, resulting in comparable performance for each burner and improving the overall performance of the heater.
