 Customers often ask: What is a flue gas waste heat recovery boiler? What are its characteristics? Today, ZBG Boiler Group, as a professional flue gas waste heat boiler manufacturer in Henan, gives the answer to this question.

  The flue gas waste heat recovery boiler is a kind of boiler equipment that recovers and utilizes the high temperature flue gas waste heat discharged during the production of the enterprise to produce hot water or steam for use in other sections.

  The flue gas waste heat boiler is composed of a steam drum, downcomer, riser, and waste heat recovery device. The softened water enters the steam drum through the water inlet of the steam drum, and enters the header along the downcomer. The header evenly distributes the water to the heat exchange tube group. At the same time, the flue gas passes through one side of the heat exchange tube group and the other side to transfer the water It is heated into steam, and the steam enters the header at the other end along the heat exchange tube, enters the steam drum through the riser, is filtered by the steam-water separator, and flows out through the steam outlet.

  The whole device has simple structure, convenient use, long service life, high heat transfer efficiency, and is suitable for the recovery and utilization of high-temperature flue gas generated by large-scale furnace bodies in industrial production.

It should be pointed out that the flue gas waste heat recovery boiler does not burn during the whole process. In practical applications, most waste heat boilers use high temperature flue gas from 300°C to 1000°C, mainly involving glass kilns, cement kilns, carbon kilns, three chemical wastes, hazardous wastes and other industries.

  Features of flue gas waste heat recovery boiler:

  1. The vertical arrangement is adopted, and the flue gas is heated by the convection tube bundles when the flue gas is scoured laterally, and the flue gas passes through without dead corners.

  2. Low flue gas resistance and low consumption of auxiliary machinery.

  3. The flue gas flow has no diffusion and shrinkage, and the scour is evenly distributed, giving full play to the role of the heating surface, and avoiding local dust and abrasion.

  4. The flue gas flow has a large cross-sectional area, reasonable smoke velocity, and tube bundle wear, which is conducive to smoke and dust deposition.
