Abstract

The invention discloses a partial jet flow small circulating ratio pipe casing type high temperature waste heat steam boiler. The partial jet flow small circulating ratio pipe casing type high temperature waste heat steam boiler comprises a boiler cylinder and a pipe casing type evaporation heat exchanger which are vertically arranged; the boiler cylinder and the pipe casing type evaporation heat exchanger are arranged in a horizontal type; the boiler cylinder and the pipe casing type evaporation heat exchanger are connected through an ascending pipe assembly and a declining pipe assembly; the boiler cylinder is connected with a water inlet connecting opening formed in the pipe casing type evaporation heat exchanger through a high temperature high pressure water pipe; a high temperature high pressure water pump is arranged on the high temperature water pipe. The partial jet flow small circulating ratio pipe casing type high temperature waste heat steam boiler has the advantages of being small in circulating ratio, efficient and energy saving, long in service life, small in occupied space, benefited to site installation and original facility reconstruction and reasonably utilizing high temperature flue gas waste heat in the chemical engineering field.

Description

technical field

[0001] The invention belongs to the technical field of high-temperature flue gas waste heat utilization equipment, and in particular relates to a shell-and-tube high-temperature waste heat steam boiler with small circulation rate and partial jet flow. Background technique

[0002] The high-temperature flue gas discharged from various process equipment is a source of energy with great development potential, such as: metallurgical furnaces, heating furnaces, industrial kilns, fuel gasification devices, etc., all of which have a large amount of flue gas discharged up to 1000 °C. At present, there are still a large amount of high-temperature waste heat in our country that has not been fully developed, and even a part of it has not been fully developed.

[0003] At present, due to the high temperature and large flow of high-temperature flue gas in the tube side of the high-temperature waste heat steam boiler, the high-temperature gas directly scours the weld seam ...
