Tail heat absorption device of saturated steam boiler

Abstract

The invention discloses a tail heat absorption device of a saturated steam boiler. The tail heat absorption device comprises a steam box, a heat exchange chamber, a flow stabilization tube, a heat collecting chamber and a heat control tube. A steam tube is installed inside the steam box, a heat conduction tube is installed above the steam tube, an insulating layer is installed inside the steam box, the heat exchange chamber is installed below the steam box, and a heat exchanger is installed inside the heat exchange chamber; a gas injection tube is installed on the left side of the heat exchanger chamber, the flow stabilization tube is installed below the heat exchange chamber, the heat collecting chamber is installed below the flow stabilization tube, and the heat control tube is installed inside the heat collecting chamber; and a fixing plate is installed inside the heat collecting chamber, a control knob is installed on the surface of the steam box, an indication lamp is installed on the surface of the flow stabilization tube, and a display screen is installed on the surface of the heat collecting chamber. According to the tail heat absorption device, the stem tube is of a concentric-square-shaped rotation structure, it is allowed that water flow in the steam tube boils, steam locking is avoided, and tube explosion is also avoided.

Description

technical field [0001] The invention relates to the technical field of heat absorbing devices, in particular to a tail heat absorbing device of a saturated steam boiler. Background technique [0002] In a saturated steam boiler, the heat absorption of the boiler furnace usually accounts for about 60% of the total heat absorption, and the heat absorption at the tail of the boiler accounts for about 40% of the total heat absorption. For the heat device, for the economizer made of cast iron, it will cause the economizer to explode. For the economizer made of steel, the boiling degree of water should not exceed 25%. If it exceeds 25%, under the action of steam resistance, It will also burst the tube. The disadvantages of the end heat absorbing device of the saturated steam boiler with the above structure are: the use of the upper steam drum and the lower steam drum at the same time makes the manufacturing cost high, the floor area is large, and the structure is not compact, resu...

[0002] In a saturated steam boiler, the heat absorption of the boiler furnace usually accounts for about 60% of the total heat absorption, and the heat absorption at the tail of the boiler accounts for about 40% of the total heat absorption. For the heat device, for the economizer made of cast iron, it will cause the economizer to explode. For the economizer made of steel, the boiling degree of water should not exceed 25%. If it exceeds 25%, under the action of steam resistance, It will also burst the tube. The disadvantages of the end heat absorbing device of the saturated steam boiler with the above structure are: the use of the upper steam drum and the lower steam drum at the same time makes the manufacturing cost high, the floor area is large, and the structure is not compact, resulting in the heat absorption effect. bad
