Rapid heat absorption pipe for boiler and heat absorption boiler using heat absorption pipe

The invention relates to a rapid heat absorption pipe for a boiler and a heat absorption boiler using the heat absorption pipe. The heat absorption pipe is a straight pipe, a plurality of heat absorption fire-resisting walls are arranged in the straight pipe in the length direction at intervals in a staggered mode, and the height of each heat absorption fire-resisting wall is less than the diameter of the straight pipe and larger than the radius of the straight pipe. The heat absorption boiler comprises a boiler outer container, wherein a combustion chamber is arranged on the inner bottom surface of the boiler outer container through a base, the top of the combustion chamber is connected with a plurality of rapid heat absorption pipes communicating with the combustion chamber, the top ends of the rapid heat absorption pipes are jointly connected with a chimney through a sealing head, and the upper end of the chimney extends out of the boiler outer container. The heat absorption pipe can be suitable for variou
