Abstract: A scroll heating device includes a base, a reaction region, and a first and a second channel. The reaction region is at the center of the base. The two channels are located on the base and extend spirally from the reaction region toward the periphery of the base. The width of each channel is gradually reduced as the channel extends from adjacent to the center of the base toward the periphery of the base. The first channel allows a gas that flows into the first channel through the periphery of the base toward the center of the base to flow toward the reaction region at a progressively slower rate, enter the reaction region slowly through the gradually widening first channel, and therefore stay in the reaction region for longer. The combusted exhaust enters the second channel from adjacent to the center of the base and exits through the periphery of the base.
