冲天炉预热送风新型换热器的研制

Development of a New Type Heat Exchanger for Preheating Hot Blast Cupola

针对目前铸造行业普遍采用的冲天炉密筋热风炉胆存在的热风温度低，使用寿命短的问题，研究了一种既能提高热风温度又能提高使用寿命的冲天炉两次换热式空气预热热交换器，通过试验，取得较理想的技术经济效果。该项新技术已获得国家实用新型专利（专利号ZL94231634．7）．

Aiming against the disadvantages of low blast temperature and short service life commonly presenting in the conventional air preheating jacket with close ribs for hot blast cupola, a new type heat exchanger of two atages heat exchang has been developed to increase blast temperature and prolong the service life. As proved, excellent technical-economic effects are obtained. This new technology has taken out for a patent of National Practice New Type Patent(Patent No. ZL94231634.7)
