The problem of low efficiency.
The technical solution of the utility model is achieved in that
A kind of fuel vapor low-carbon vacuum boiler includes shell, has combustion chamber in the shell, is equipped with outside the shell
Combustor, the end of combustor protrude into enclosure interior and and combustion chamber, the combustor and combustion chamber and shell it is close
Envelope, the combustion chamber are connected with the multiple heating tubes being circumferentially arranged around burning chamber axis, have between the combustion chamber and shell
Filled with heat medium water, it is negative pressure vaporium in the shell of the heat medium water upper end, has in negative pressure vaporium and be axially connected to shell
The heat-exchange tube at both ends, the heat-exchange tube are two, the upper end of the shell have with the vacuum meter of negative pressure steam chambers,
Pressure limiting valve and vacuum pump, radially have multiple cooling fins on the outer wall of the heat-exchange tube, and cooling fin can pass through suction
Heat and so that the water in heat-exchange tube is rapidly heated, to improve the exchange capability of heat of entire vacuum boiler.
Specifically, two heat-exchange tubes are connect with heating pipe and domestic water line respectively.
Further, the length of the heating tube is less than the length of combustion chamber.
Further, the combustor is oil gas combustor.
The beneficial effect is that: using water, low-temperature boiling generates steam to the vacuum boiler of the utility model under low pressure, leads to
Carbonated drink condensation heat transfer mode is crossed to export heat, combustion chambers burn heating make heat medium water boil in negative pressure vaporium vaporization generation
Negative pressure vapor, vapor condense outside heat-exchange tube and its cooling fin, by pipe inner cold water heat temperature raising and pass to user, and water steams
Formation water droplet flows back to heat medium water and reheats vaporization after airsetting knot, completes entire circulation.What is be arranged on heat-exchange tube outer wall is multiple
Radial cooling fin enhances the exchange capability of heat of heat-exchange tube, to enhance the production efficiency of vacuum boiler.With in the prior art
Vacuum boiler compare, produce same hot water and heating, the oil gas that the utility model needs is less, excellent with low-carbon environment-friendly
Point.
