Gas steam generating equipment

Abstract

The invention discloses gas steam generating equipment, and belongs to the technical field of steam generating equipment. The gas steam generating equipment comprises a plurality of groups of steam generating modules; each steam generating module comprises a combustion chamber, a finned heat exchanger, a tubular light tube heat exchanger and a combustor; the finned heat exchanger, the tubular light tube heat exchanger and the combustor are sequentially arranged in the combustion chamber from top to bottom; the tubular light tube heat exchanger comprises a stratosphere, an upper circulation layer and a lower circulation layer which are arranged from top to bottom; multiple sets of heat exchange light tubes are arranged on different flow layers; the heat exchange light tubes of the stratosphere are sequentially connected in series; and the heat exchange light pipes of the upper circulation layer and the lower circulation layer are alternately connected in series and in communication with the heat exchange light tubes of the stratosphere. Liquid water flows into the tubular light tube heat exchanger from the upper circulation layer after flowing through the finned heat exchanger, absorbs heat in the flowing process to form steam, and alternately and circularly flows between the upper circulation layer and the lower circulation layer, and the heat exchange effect and the steam quality are improved through alternate circulation flow between the upper circulation layer and the lower circulation layer.

Description

technical field [0001] The invention relates to the technical field of steam generating equipment, in particular to a gas steam generating equipment. Background technique [0002] The existing steam generation equipment mainly provides heat for the water in the exchanger through gas heating or electric heating. Compared with the steam generation equipment heated by electric energy, the steam generation equipment using gas heating has a faster response speed and is suitable for large-scale steam supply. However, the use of gas heating will consume a large energy loss in the process of generating steam. In order to further promote the use of steam energy, it is necessary to improve the efficiency of gas-fired steam generation equipment and make full use of the energy released by gas combustion. Contents of the invention [0003] In order to overcome the defects in the prior art, the present invention provides a gas steam generating device. [0004] The technical solution ad...
