Claims

[Claims for Utility Model Registration] (1) Both the upper header 1 and the lower header 2 are formed in an annular shape, and the upper and lower headers 1 and 2 are connected by a number of vertical water pipes, and these water pipes are arranged at intervals in the radial direction. are arranged as two concentric annular water tube rows 3 and 4, and each water tube in the outer annular water tube row 4 is connected by a spacer 5, so that the inner annular water tube row 3 and the outer annular water tube row 3 are connected to each other by a spacer 5. A combustion gas passage 6 is formed between the water tube row 4, and an opening 7 extending over the entire length of the tube is provided in the inner annular water tube row 3 to form a combustion gas passage 6 between the combustion chamber 8 and the combustion gas passage 6.
The outer annular water tube row 4 is provided with an opening 9 spanning the entire length of the tubes to connect the combustion gas passage 6 and the flue 1.
In a multi-tube once-through boiler that communicates with
A temperature sensing member 12 provided with a bottomed hole 11 is provided on the outer surface of the outer water pipe on the combustion gas passage 6 side through the spacer 5, and a temperature sensor 13 is inserted into the hole 11 of the temperature sensing member. A temperature sensor for water tubes in multi-tube once-through boilers. (2) The bottom part 14 of the hole 11 of the temperature-sensitive member is connected to the center line A connecting the center _O1 of the boiler and the center _O2 of the outer water tube, and from the center _O2 of the outer water tube toward the upstream side of the combustion gas passage 6. A utility model registration claim characterized in that a temperature sensing member 12 is provided on the outer surface of the outer water pipe so that the temperature sensing member 12 is located on the outer surface of the outer water pipe within a range where the angle θ with respect to the extending radial direction radiation B is 60 degrees or less. A water tube temperature sensor in a multi-tubular once-through boiler according to scope 1.
