Problems solved by technology
After the flue gas flows into the flue gas heat exchanger, because the dust carried by the flue gas is easy to wear the heat exchange tubes, usually 3-5 rows of anti-wear dummy tubes are usually installed on the windward side module to prevent wear on the subsequent heat exchange tubes. Does not participate in heat exchange, but increases the overall weight of the equipment, wasting a certain volume and manufacturing costs
In addition, due to the tight overall arrangement of the flue gas heat exchanger, the entire module needs to be replaced uniformly when replacing it. For a relatively narrow installation position, the overall replacement will cause inconvenience

The invention provides a wear-resistant flue gas heat exchanger. The heat exchanger comprises a plurality of groups of heat exchange pipelines, a new header heat exchange pipeline, a water inlet header, a water outlet header and a wear-resistant false pipe, wherein the plurality of groups of heat exchange pipelines are arranged between the water inlet header and the water outlet header, the new header heat exchange pipeline is arranged at one side close to the water outlet header, and the wear-resistant false pipe is arranged at one side close the new header heat exchange pipeline. The invention further provides an adjustment method utilizing the wear-resistant flue gas heat exchanger. Through the heat exchanger, limited flue arrangement space can be fully utilized, and under the same budget, a heat exchange area is arranged as large as possible, so that unnecessary waste is reduced. Meanwhile, operation flexibility of the flue gas heat exchanger is improved, and under the situation oflocal wear, overall operation of equipment is not disturbed, so that equipment reliability is improved.
Description
technical field [0001] The invention relates to the technical field of flue gas heat exchangers for low-temperature economizers, in particular to an anti-wear flue gas heat exchanger and an adjustment method. Background technique [0002] In the common low-temperature economizer flue gas heat exchanger, the flue gas heat exchanger is composed of an array of modules with similar structures. After the flue gas flows into the flue gas heat exchanger, because the dust carried by the flue gas is easy to wear the heat exchange tubes, usually 3-5 rows of anti-wear dummy tubes are usually installed on the windward side module to prevent wear on the subsequent heat exchange tubes. It does not participate in heat exchange, but instead increases the overall weight of the equipment, wasting a certain volume and processing and manufacturing costs. In addition, due to the tight overall arrangement of the flue gas heat exchanger, the entire module needs to be replaced uniformly during rep...
