发明名称 WASTE HEAT RECOVERY SYSTEM OF COKE OVEN ASCENSION PIPE
摘要 <p>PURPOSE: A waste heat recovery system of coke oven ascension pipe is provided to directly convert heat energy retained by dry distilled gas into electrical energy so that it is recovered by attaching a thermoelectric semiconductor device onto the outer wall surface of the ascension pipe and air cooling the outer part thereof. CONSTITUTION: The waste heat recovery system of coke oven ascension pipe is characterized in that heat energy retained by dry distilled gas(3) is directly converted into electrical energy by attaching a thermoelectric semiconductor device(18) for forming electrical load(13) and closed circuit onto the outer wall surface of ascension pipe of coke oven and air cooling the outer part of the thermoelectric semiconductor device(18) attached onto the outer wall surface of the ascension pipe of the coke oven so that the dry distilled gas of high temperature passing through the ascension pipe for the thermoelectric semiconductor device(18) functions as a heat source, wherein the thermoelectric semiconductor device(18) is characterized in that P type semiconductor(9) and N type semiconductor(10) are alternately arranged, electrodes(11) are alternately connected to upper and lower surfaces of the P type semiconductor(9) and N type semiconductor(10), and insulation plates(12) are installed on the outer surface of each of the electrodes(11) so that an upper insulation plate(12) is contacted with a heat source(14) of the high temperature side, and a lower insulation plate(12) is contacted with a heat source(15) of the lower temperature side.</p>
