Claims

[Claims for Utility Model Registration] 1. A furnace comprising a girder that supports a bottom tube of a peripheral wall of a boiler, a support beam fixed to the peripheral wall of the boiler, and a roller that supports the girder so that it can be displaced with respect to the support beam. In the bottom wall support structure, the contact surfaces of the roller with the girder and the support beam are each formed into an arc shape, and the arc length of the side that contacts the support beam is longer than the arc length of the side that contacts the girder. The support structure of the furnace bottom wall is characterized by its length. 2. A furnace bottom wall support structure consisting of a girder that supports a peripheral wall bottom tube of a boiler, a support beam fixed to the peripheral wall of the boiler, and a roller that supports the girder in a movable manner with respect to the support beam. 1. A support structure for a furnace bottom wall, characterized in that contact surfaces of the roller with the girder and the support beam are each formed in an arc shape, and a roller fall prevention spring is attached between the roller and the support beam.
