Abstract

The invention relates to a flue gas waste heat recovery system, in particular to a flue gas waste heat recovery system for an industrial gas boiler. According to the flue gas waste heat recovery system for the industrial gas boiler, the heat energy utilization rate is increased. A flue gas waste heat recovery system for an industrial gas-fired boiler comprises a base, a boiler, a discharge flue, an energy saver, a pressurization box, a water inlet pipe, a pressurization rod and the like. A boiler is arranged on the left side of the top of the base, a discharge flue is arranged on the right upper portion of the boiler, an energy saver is arranged on the right side of the top of the base and connected with the boiler, pressurizing boxes are connected between the front side and the rear side of the lower portion of the discharge flue and the energy saver, water inlet pipes are connected between the right upper portion of the discharge flue and the lower portions of the pressurizing boxes, and pressurizing rods are arranged on the upper portions of the pressurizing boxes in a sliding mode. When the driving mechanism operates, the four first shifting blocks are driven to intermittently flap the water inlet pipe, so that water drops condensed and attached to the outer wall of the coiled pipe drop downwards, and flue gas waste heat recovery is prevented from being affected.

Description

technical field [0001] The invention relates to a flue gas waste heat recovery system, in particular to a flue gas waste heat recovery system for industrial gas boilers. Background technique [0002] Industrial gas-fired boilers are common industrial equipment that heat clean water at 15-25°C to boil and produce high-temperature steam. The fuel used is mainly gas, which consumes a lot of energy, and the problem of energy shortage has always existed. Composed of many devices, the waste heat recovery system is only a part of the industrial gas boiler system used to recover the waste heat of the flue gas. At present, the waste heat of the industrial gas boiler has not been fully and effectively recovered in time, resulting in a waste of energy. In order not to affect the industry Sustainable development, while responding to the national call for energy conservation and emission reduction, it is necessary to reasonably and efficiently recover these waste heat. [0003] Patent a...
