烟道式余热锅炉
Flue type waste heat boiler
产品特点
Products characteristics
余热锅炉具有其回收“余热的特殊性"，所以在设计余热锅炉时， 必须对余热的特殊性给予考虑。当工业炉排烟温度大于500°C时， 装设余热锅炉产生蒸汽其效果是十分显著的，在一般的情况下，如大， 中，小型钢管厂在每一只退火炉窑上，都可以安装一台余热锅炉。 余热锅炉的结构形式采用卧式烟管传热的原则，锅炉安装在炉窑上 面，把锅筒、筒体的三分之一放在炉窑内进行直接受热，再通过直 排烟管进行三个回程，使大量的烟气在烟管内传热，炉窑的烟气流 量大致在4500〜6000m3/h时，都可以安装一台一吨的余热锅炉来 提供生产用汽。
The waste heat boiler has the particularity of recovering the waste heat, so it is necessary to consider the particularity of the waste heat when designing the waste heat boiler. When the exhaust gas of industrial furnace temperature greater than 500 DEG C when installing waste heat boiler to generate steam and its effect is very significant, in general, such as large, small steel plant on each furnace kiln, can install a waste heat boiler. The structure form of the waste heat boiler adopts horizontal pipe heat transfer principle, boiler installed in the furnace above, the drum, the cylinder 1/3 is placed in direct heating furnaces, and then a three return straight through the exhaust pipe, so that a large number of flue gas in the smoke pipe heat transfer, flue gas flow is generally in 4500~6000m3/h furnace can be installed, one ton of waste heat boiler to provide steam production.
