The lower components are primarily the combustion equipment. The two main parts can be instantly installed and manufactured. Only the boiler wall and back arc of the upper and low main parts need to be constructed. Connect the smoke wind tunnel with the pipeline, meter, valve and the coal saver before pouring the front arc.Structure: 1) Upper and lower cylinder diameter:
