Vertical oil and gas fired shell boiler adopting novel heat exchange mode

The invention provides a vertical oil and gas fired shell boiler adopting a novel heat exchange mode. The vertical oil and gas fired shell boiler comprises a vertical boiler body filled with boiler water, a boiler furnace used for generating flue gas with heat, a smoke chamber and multiple heat exchange pipes; the gas inlet end of the smoke chamber is communicated with the boiler furnace, the gas outlet end of the smoke chamber is connected with a chimney arranged at the top of the smoke chamber, and smoke is exhausted; the multiple heat exchange pipes are arranged in the smoke chamber at intervals, the two ends of each heat exchange pipe are connected with the smoke chamber and communicate with the exterior of the smoke chamber, and boiler water circulates in the heat exchange pipes; and the heat exchange pipes are finned tubes with fins for increasing the heat exchange area at the outer sides. According to the vertical oil and gas fired shell boiler, the smoke chamber and the heat exchange pipes with the fi
