Title
(EN) SYSTEM FOR HEATING HEAT-TRANSFER OIL USING BOILER FLUE GAS WASTE HEAT
(FR) SYSTÈME POUR CHAUFFER DE L'HUILE DE TRANSFERT DE CHALEUR UTILISANT LA CHALEUR PERDUE DU GAZ DE COMBUSTION D'UNE CHAUDIÈRE

Abstract
(EN) A system for heating heat-transfer oil using boiler flue gas waste heat, comprising an economizer (3) and an air pre-heater (4) disposed in the flue (1) according to the direction of the smoke flow; and further comprises a heat-transfer oil heater (2) disposed in front of the economizer (3) in the flue (1), the heat-transfer oil heater (2) is connected to a heat-using device (19) through a circulation pipe, and a circulation pump (12) is disposed on the circulation pipe. The system for heating heat-transfer oil using boiler flue gas waste heat of the present invention, exploits flue gas waste heat, reduces the exhaust gas temperature of the boiler, utilizes recycled heat to heat a heat carrier, and can be used in numerous industries.
(FR) L'invention porte sur un système destiné à chauffer de l'huile de transfert de chaleur en utilisant la chaleur perdue du gaz de combustion d'une chaudière, ce système comprenant : un économiseur et un préchauffeur d'air disposés dans le conduit de fumée, dans le sens de l'écoulement de la fumée; et comprenant en outre un réchauffeur d'huile de transfert de chaleur disposé en avant de l'économiseur dans le conduit de fumée, le réchauffeur d'huile de transfert de chaleur est relié à un dispositif consommateur de chaleur par un tube de circulation, et une pompe de circulation est disposée sur le tube de circulation. Dans le système destiné à chauffer de l'huile de transfert de chaleur qui utilise la chaleur perdue du gaz de combustion d'une chaudière selon la présente invention, la chaleur perdue du gaz de combustion est entièrement utilisée et, grâce au changement de l'ordre de l'arrangement des surfaces chauffées de la partie arrière de la chaudière, la température des gaz usés de la chaudière est abaissée tandis que le rendement et la puissance de la chaudière sont assurés, une partie de la chaleur perdue des gaz de combustion de la chaudière est recyclée et la chaleur recyclée est utilisée pour chauffer un caloporteur, l'huile de transfert de chaleur. Le système est applicable aux domaines du pétrole, de l'ingénierie chimique, du textile, de l'impression et de la teinture, du caoutchouc, du tannage, de l'industrie alimentaire, du traitement du bois et analogues.
(ZH) 一种用锅炉烟气余热加热导热油的系统,包括按烟气流经方向设在烟道(1)内的省煤器(3)和空预器(4),还包括导热油加热器(2),设在烟道(1)内省煤器(3)的前方,导热油加热器(2)通过循环管与用热设备(19)相连,循环管上设有循环泵(12)。用锅炉烟气余热加热导热油的系统充分利用了烟气余热,降低锅炉排烟温度的同时,将其回收的热量加热热载体,可应用于许多行业。
