Embodiment Construction

[0012] figure 1 ,figure 2, image 3 , Figure 4 It is a way of concrete implementation. Describe its construction according to the manufacturing process.

[0013] 1. Process the inner water jacket 7. The inner water jacket 7 is welded by steel plates such as image 3 The double-layer closed cylinder shown in the figure has holes for furnace doors 18, 21, 23, holes for exhaust pipe 4, holes for blasting branch pipe 12 in the air-making chamber, and steam outlet pipe 27, The hole of water outlet pipe 6 and exhaust pipe.

[0014] Second, processing the outer hot air jacket 11. Outer hot air cover 11 is welded into such as by steel plate Figure 4 As shown in the double-layer closed cylinder, its inner diameter is greater than the outer diameter of the inner water jacket, and the two cylinders can form a flame burning space after they are put together; all holes corresponding to the inner water jacket 7 must be processed on the cylinder; except In addition, an exhaust pipe...

Abstract

The invention includes a fire door, a fire hole, a grate, a hearth bottom and an insulation casing. It also comprises a double-layer internal water jacket having a water inlet and a steam (water) outlet and a double-layer external hot-air jacket. A flame-forming chamber is disposed between the grate and the hearth bottom. An enclosed fire door is set on the ash-removing hole. The ventilating branches are set on both the coal-storage gasification chamber and the flame-forming chamber. The lower port of the flame combustion room in the internal water jacket is in communication with the flame-forming chamber, and the outlet is in communication with the open air. A blast inlet is disposed at one side bottom of the double-layer hot-air jacket, and the hot-air outlet is disposed on the other side top. The top ventilation pipe of the coal-storage gasification chamber with an air-vent is connected with the exhaust pipe. The temperature controllers are set on the outer wall of the double-layer external hot-air jacket and at the steam (water) outlet, and connected to the controller.

Description

technical field [0001] The application belongs to boilers, in particular to heating boilers. Background technique [0002] At present, all kinds of heating boilers, regardless of steam heating or water heating, burn hot water or steam, and realize heating through the circulation of radiators. , water (steam) outlet and water pipe grate and other components. The water pipe grate is set in the combustion chamber, and the combustion chamber leads directly to the high chimney through the flue. A double-layer furnace tube is arranged around the combustion chamber, or a tube-and-tube exchanger is arranged in the flue to increase the heat exchange effect and make full use of heat energy. In the above-mentioned boiler, the coal is directly burned in the combustion chamber, and the uncombusted gas is exhausted from the flue and discharged into the atmosphere. The heat utilization rate is less than 30%, and the exhaust gas pollutes the atmosphere. In addition, the above-mentioned h...
