Embodiment 1

[0023] Embodiment 1: as figure 1 , Figure 4 , Figure 5 As shown in the figure, a new furnace for recovering waste heat to generate electricity includes a furnace chamber, which is divided into upper and lower layers. It is composed of an upper furnace chamber 1, a middle furnace chamber 2 and a lower furnace chamber 3. The middle furnace chamber 2 of the middle layer is the slag storage area, and the lower furnace chamber 3 of the lower layer can be the installation area of ​​the semiconductor thermoelectric power generation device. The stability of the furnace body also increases with the decrease of the temperature of the three layers, and the increased heat transfer area is used to enhance heat transfer and improve power generation performance. An upper orifice plate 19 is provided between the upper furnace chamber 1 and the middle furnace chamber 2 , and a layered partition 11 is provided between the middle furnace chamber 2 and the lower furnace chamber 3 .

Description

Technical field: [0001] The invention relates to a novel furnace for generating power by recovering waste heat, in particular to a novel furnace capable of recovering waste heat from slag, furnace wall and smoke exhaust to generate power by temperature difference, and belongs to the technical field of energy recovery and utilization. Background technique: [0002] The small coal-fired stove is a tool for cooking throughout the year or heating in winter in the vast rural areas of our country. When the coal-fired stove burns, the temperature of the outer furnace wall is very high, and the combustion generates slag with a lot of heat, and the slag contains a lot of heat. The flue gas also contains a large amount of waste heat, which has not been effectively utilized at present, resulting in the problem of waste heat waste. These high-temperature waste heat is a good high-level heat source and should be utilized. However, when using coal-fired stoves in rural areas, CO poisonin...
