Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam generator technology, and in particular to a high-efficiency steam generator with a waste heat recovery device. Background Technology
[0002] A steam generator is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam, and it is widely used in many industrial fields. It mainly includes three processes: water heating, vaporization, and steam generation and transportation. Water is pumped into the heating chamber by a feedwater pump, where it exchanges heat with fuel in the combustion chamber. The water temperature rises to its boiling point and begins to vaporize. The generated steam accumulates at the top and is transported to the equipment or system using it through pipelines.
[0003] When a steam generator is in use, the combustion of fuel produces a large amount of high-temperature gas. However, existing steam generators cannot recover and utilize the high-temperature gas produced by combustion. They are usually discharged directly from the equipment, resulting in a large waste of heat energy. In addition, the gas produced by combustion contains a large number of impurities, which will also pollute the surrounding production environment if discharged directly. Utility Model Content

A heat recovery mechanism is installed inside the generator body 1, consisting of a collection pipe 8, a heat conduction pipe 9, and a connecting pipe 10. The heat conduction pipe 9 is spiral-shaped and made of copper metal, which provides stronger thermal conductivity and facilitates the transfer of steam...

The suction mechanism, through the purification component and the heat recovery mechanism, draws the high-temperature gas generated inside the generator body 1. The high temperature is then conducted into the water pipe 6 through the heat recovery mechanism to preheat the water source and improve heating efficiency. The purification component adsorbs and filters impurities in the gas, achieving the goal of conveniently recovering and purifying the high-temperature gas generated in the steam generator. This avoids the problem of a large amount of heat energy wasted and the pollution of the surrounding production environment caused by the direct emission of the gas generated by combustion, and solves the problems mentioned in the background art.
