Abstract

The invention discloses a steam boiler heat recovery and energy saving utilization method and belongs to the field of heat pumps. The steam boiler heat recovery and energy saving utilization method is used for solving the heat recovery problem. According to the technical key points, the method comprises 1, a waste heat recovery mode which comprises boiler periodic pollution discharge and heat recovery and boiler continuous pollution discharge and heat recovery; 2, a dry-burning descaling operation mode; 3, a thermal deaeration operation mode; and 4, a boiler flue gas waste heat recovery and energy saving water supply operation mode.

Description

Technical field [0001] The invention belongs to the field of heat pumps and relates to a heat recovery system. Background technique [0002] Pressure-bearing steam boilers have to carry out blowdown under pressure at least once a day, and the discharged high-temperature water takes away a lot of heat, which is basically not recovered. In the current environment, the production costs of enterprises need to be controlled from all aspects; if this part of the heat can be recovered, a large amount of thermal energy can be saved, and the thermal pollution caused by the emitted heat can also be reduced. Summary of the invention [0003] In order to solve the above heat recovery problem, the present invention proposes the following technical solution: a steam boiler heat recovery and energy-saving utilization method, using a steam boiler heat recovery and energy-saving utilization system, executes the following steps: [0004] S1. Waste heat recovery mode: [0005] Regular boiler blowdown ...
