Abstract
A heat regenerative type afterheat steam boiler integrates an in-tube siphon circulation counterflow heating climbing-film evaporator, a heat regenerator and a steam jet ejector. The heat regenerative type afterheat steam boiler has the advantages that climbing-film evaporation on the inner side of a circularly-distributed perpendicular heating tube bundle and a central cylinder descending passage form siphon circulation to enhance heat transfer and prevent scaling; by the aid of the heat regenerator, on one hand, steam pressure is enhanced, and on the other hand, afterheat utilization ratio of the boiler is increased; perpendicular washing of the outer side of the circularly-distributed perpendicular heating tube bundle is achieved to enhance heat transfer of high-viscosity afterheat media such as lubricating oil; the heat regenerative type afterheat steam boiler uses overbottom pressure of a steam pipe network for driving the steam jet ejector to compress steam, thereby being highly efficient and simple.
