However, the heat absorbing plate is suspended on both sides and is relatively thin, and the temperature of the flue gas is relatively high. The heat absorbing plate is easily deformed due to the high heat, which affects the rise of the flue gas and also affects the connection between the mounting hole and the heat absorbing tube.
