Description

Technical Field

[0001] This invention relates to the field of steam waste heat recovery technology, specifically to a steam waste heat recovery and utilization device for industrial plants. Background Technology

[0002] Waste heat recovery refers to the process of capturing and reusing heat generated during industrial production, power generation, or other energy consumption. This heat is usually lost to the environment as waste heat, but through waste heat recovery technology, it can be used to heat water, heat buildings, drive absorption chillers, etc. This technology helps reduce energy consumption, save costs, and reduce negative environmental impacts.

[0003] In gas-fired, coal-fired, or biomass-fired steam boilers, if the fuel contains moisture, it will absorb heat during combustion, forming steam that is emitted with the flue gas. In this case, the drying effect of the high-temperature flue gas can be utilized by adding a fuel dryer. This allows the flue gas to directly dry the fuel or heat the air to dry it, thereby reducing the fuel's moisture content and improving energy efficiency. However, existing devices for recovering steam waste heat typically simply spread the fuel evenly on the steam waste heat discharge pipe. This drying method only dries fuel in a localized area, resulting in low efficiency in utilizing steam waste heat. Therefore, there is an urgent need for an industrial plant steam waste heat recovery and utilization device to solve this problem. Summary of the Invention
