ABSTRACT:
A steam injector system comprises a plurality of steam injectors each being provided with with a check valve adapted for water supply, a check valve adapted for steam supply, a check valve adapted for overflow and a check valve adapted for discharge and the respective water check valves, steam check valves, overflow check valves and discharge check valves are connected. In another aspect, a steam injector system comprises a plurality of first to last stage steam injectors arranged in series with each other, the last stage steam injector being provided with a relief valve disposed at a last stage overflow drain port, and a pressure pulsation absorbing device is disposed at least between the last stage overflow drain valve and the relief valve. A steam injector of an improved structure comprises an outer casing, a water nozzle disposed in the casing so as to extend axially therein, a central steam nozzle disposed inside the water nozzle coaxially therewith, a steam-water mixing nozzle disposed on a downstream side of the water nozzle and the central steam nozzle, and a peripheral steam nozzle mounted to the casing at a portion to supply steam from an outside into the steam-water mixing nozzle, wherein the steam is supplied so as to flow inside and outside the water.
