Zusammenfassung:The invention discloses an evaporation chamber of a vacuum hot water boiler, comprising a boiler cavity, wherein the upper half part of the boiler cavity is a heat exchange cavity, the lower half part of the boiler cavity is an evaporation cavity in which a hearth and a smoke tube are arranged, heat exchange tubes are arranged in the heat exchange cavity, and the cross section of the top part of the heat exchange cavity is a circular arc. The evaporation chamber of the vacuum hot water boiler also comprises a rectification barrel which is sheathed outside the heat exchange tubes and comprisesa barrel body, both ends of the barrel body are provided with fixed ends, the upper half part between the two fixed ends of the barrel body is provided with a vapor inflow port, and the bottom of thebarrel body is provided with more than two condensed water outflow channels. By adopting the evaporation chamber of the vacuum hot water boiler, on one hand, the flow rate of water vapor is increasedso that the heat exchange e
