Claims (1)

[Scope of utility model registration request] A snow melting tank 5 is provided on the upper surface of this working chamber 3, which is arranged on the upper surface of the underframe 2, which has a rectangular planar structure, through a first flue 4. It is composed of a chamber 6 and a water chamber 7 arranged around the outer periphery of the combustion chamber 6 so as to surround the combustion chamber 6, and a top plate 7A of the water chamber 7 has an appropriate number of truncated conical protrusions 7B. A steam pipe 7C is installed on the top surface of the protrusion 7B, the bottom of the first flue 4 is the top plate 7A of the water chamber 7, and the ceiling is the snow melting tank. The first
The bottom rear part of the flue 4 and the rear upper part of the combustion chamber 6 are communicated with each other by a smoke outlet pipe 6A, and inside this first flue there is a smoke guiding plate 4B stretched in the front-rear direction.
The structure is such that the heat-containing smoke from the smoke outlet pipe 6A is guided to a second flue, which will be described later, while meandering as shown by an arrow. are front wall 5B, rear wall 5C
, a left wall 5D, and a right wall 5E are arranged in series, and the front wall 5B, left wall 5D, and right wall 5E are configured as a hollow second flue 5F, and have a chimney-shaped exhaust port 5B1. are connected to the central upper surface of the front wall 5B, and the first flue 4 and the second flue 5F are connected to the left wall 5D and the right side through a smoke outlet 4C provided in the surrounding wall 4A. A groove-shaped snow melting water outlet 9 is provided below the rear wall 5C of the snow melting tank 5 and communicates with the rear part of the wall 5E, and the steam pipe 7C from the water chamber 7 is connected to the first flue. 4, its tip protrudes outward from the bottom plate 5A of the snow melting tank, and a steam outlet is provided in the side wall.
The snow melting water retainer 10 connected to the rear of the first flue 4 is composed of a bottom plate 10A and a side wall 10B, and is configured so that the snow melting water from the snow melting water outlet 9 flows into the snow melting water retainer 10. This snow melting device is characterized by being provided with a circulation pipe 10C for circulating a part of the snow melting water back into the water chamber 7, and a snow melting water discharge pipe 10D.
