Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a boiler screen-type reheater with an angle adjustment function. Background Art

[0002] The boiler platen reheater is a vital heat exchange device in the power plant boiler system. Its main function is to use the heat of the flue gas to reheat the steam to increase the temperature and pressure of the steam, thereby improving the efficiency of the entire power generation process.

[0003] However, the reheaters currently used in thermal power plants are relatively simple in structure design and cannot effectively recover the waste heat in the high-temperature exhaust gas during use, which means that thermal power plants cannot use the heat in the discharged high-temperature exhaust gas for secondary use, resulting in a large amount of energy waste and reduced efficiency. Based on this, we propose a boiler screen reheater with angle adjustment function to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.
