煙道式余熱鍋爐
Flue type waste heat boiler
產品特點
Products characteristics
余熱鍋爐具有其回收“余熱的特殊性"，所以在設計余熱鍋爐時， 必須對余熱的特殊性給予考慮。當工業爐排煙溫度大于500°C時， 裝設余熱鍋爐產生蒸汽其效果是十分顯著的，在一般的情況下，如大， 中，小型鋼管廠在每一只退火爐窯上，都可以安裝一臺余熱鍋爐。 余熱鍋爐的結構形式采用臥式煙管傳熱的原則，鍋爐安裝在爐窯上 面，把鍋筒、筒體的三分之一放在爐窯內進行直接受熱，再通過直 排煙管進行三個回程，使大量的煙氣在煙管內傳熱，爐窯的煙氣流 量大致在4500?6000m3/h時，都可以安裝一臺一噸的余熱鍋爐來 提供生產用汽。
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.
