Abstract
The invention discloses a steam boiler with heat pipes, and relates to the technology of boilers. The traditional heat pipes form a pipe bundle in a barrel of the boiler, the pipe bundle is divided into an upper section and a lower section by a partition, hot fluid flows through the lower section, and a steam cavity is formed in the upper section; and the hot fluid flows across the heat pipe bundle, and heat of the hot fluid is transmitted to the steam cavity at the upper end of the pipe bundle via the heat pipes all along, is used for heating fed water of the boiler to generate steam, and flows into a preheating section formed by double-pipe heat pipe bundles, so that fed water, which is about to be fed into the steam cavity, of the boiler can be preheated, the heat of the hot fluid is sufficiently utilized, and the temperature of drained fluid is reduced. Partitions are placed at proper positions of an upper header and a lower header, and water turns back after flowing through an inner pipe of the coldest-end double-pipe heat pipe bundle, flows to the high-temperature double-pipe heat pipe bundle, turns back, then flows to the higher-temperature double-pipe heat pipe bundle, flows to form an S shape, finally flows to the steam cavity and is sufficiently preheated. The steam boiler has the advantages that owing to the preheating section, the fed water of the boiler is sufficiently preheated, the size of the steam cavity is reduced, the pressure-bearing capacity is improved, and the boiler is compact in integral structure and high in safety.
