摘要（英）：

The invention discloses a barrel-shaped heat exchanger for a gas-fired boiler. The barrel-shaped heat exchanger for the gas-fired boiler comprises a barrel body, a top cover and a serpentine pipe. The top of the barrel body is open. The top cover is connected with the top opening of the barrel body through a flange plate and bolts. The serpentine pipe is installed inside the barrel body, and a liquid inlet and a liquid outlet of the serpentine pipe are located on the lower portion and the upper portion of the lateral wall of the barrel body respectively. The bottom of the barrel body is provided with an air inlet, and the top cover is provided with an air outlet. Through the barrel-shaped heat exchanger for the gas-fired boiler, heat carried by fuel gas can be effectively replaced to be further used, and waste of the heat and fuel gas resources is avoided.
