1. A steam heating boiler that is a sealed boiler (10) capable of being filled with water therein and discharge steam, said boiler (10) including a hollow upper groove (1) thereabove and a hollow bottom groove (2) therebelow; the volume of an upper part of said upper groove (1) being larger than the one of an lower part of said upper groove (1), and a top opening of the upper groove (1) being sealed, the volume of the hollow bottom groove (2) protruded downwardly from said lower part of the upper groove (1), an upper part of said bottom groove (2) communicated with said lower part of the upper groove (1) and an lower part of said bottom groove (2) being sealed, so that water can flow freely inside the upper groove (1) and bottom groove (2); moreover, a concave heating space (3) for fire heating formed at an external bottom of said bottom groove (2), which is characterized in that:
said bottom groove (2) formed a rectangle-shaped water storage tank while looking upward, and the heating space (3) is surrounded by the bottom groove (2) into a concave enclosed space; said heating space (3) is provided with a hollow convex groove (4) protruded downwardly from a bottom part of the upper groove (1), said convex groove (4) arranged longitudinally and connected with the upper groove (1), and both ends of said convex groove (4) communicated with the upper and lower sides of the bottom groove (2), the heating space (3) further including a heated tube (5) perpendicularly crossed with the convex groove (4) and communicated with each other, and both ends of the heated tube (5) communicated with the left and right sides of the bottom groove (2), so that water can flow freely inside convex groove (4) and heated tube (5). |
