Claims

[Claims for Utility Model Registration] A furnace body forming a space sealed by mutually opposing side walls extending in the lateral direction and end walls connected between the lateral walls at both lateral ends of the side walls; It consists of a plurality of vertically extending tubes arranged at intervals in the lateral direction, and in the lower part of the space, they are separated from each other in the width direction perpendicular to the lateral direction to form a combustion chamber. a pair of mutually opposing tube groups that are close to each other in the width direction above the chamber; an upper and lower header to which the upper and lower ends of each tube group are connected, respectively; and one end wall of the furnace body. a burner provided facing the combustion chamber; a slow-closing plate for causing combustion exhaust gas from the combustion chamber to flow alternately between both tube groups, between both tube groups and the inner surface of the side wall of the furnace body, and guiding it upward; A once-through boiler characterized in that it also includes a combustion exhaust gas discharge pipe provided at the upper center of the furnace body.
