FIELD: boiler fabrication. SUBSTANCE: the heat exchanger has a package of sections with heat-exchanging and water heating chambers, that are formed by two plates and a frame with ducts for by-passing of water and hot gas, and the water heating - by two plates with holes for inlet and outlet of water, and a contour spacer installed between them, the plates of the adjacent heat-exchanging and water heating chambers are common for them. The plates installed from the end of the package are tightened by pins. The heat exchanger practically completely consists of standardized frames and plates. EFFECT: enhanced maintainability and reduced labor content of heat exchanger mounting. 5 dwg |
