Abstract

A vertical flue composite phase change heat exchanger in the field of water feeding heaters comprises a vapor section, a steam pipeline, a condensation section, a condensation pipeline and a control system. The vapor section is arranged in a vertical flue, the upper end of the vapor section is connected with the lower section of the vapor pipeline, the upper end of the condensation section is connected with the upper end of the vapor pipeline, one end of the condensation pipeline is connected with the side face of the vapor section, the other end of the condensation pipeline is connected with the lower end of the condensation section, and the control system is respectively connected with the vapor pipeline and the condensation section. The heat exchanger solves the project application problem that an existing composite phase change heat exchanger cannot be used for the vertical flue.

Description

technical field [0001] The invention relates to a device in the field of feed water heaters, in particular to a vertical flue composite phase change heat exchanger. Background technique [0002] Boiler is one of the most important energy-consuming equipment in modern industry, which occupies a very large proportion in energy consumption. When the boiler is working, a large amount of high-temperature flue gas with heat energy will be discharged into the air, and the exhaust gas loss accounts for a very large proportion of the total energy loss of the boiler. Reducing the exhaust gas temperature of the boiler can not only effectively improve the boiler efficiency, but also reduce carbon dioxide. , nitrogen oxides and sulfide emissions, which play a very active role in protecting the environment. China has a relatively large number of boilers. The energy-saving and emission-reduction transformation aimed at the recovery of low-temperature flue gas waste heat can effectively im...
