Abstract
A liquefied gas evaporating device supplies liquefied petroleum gas to a marine engine, wherein the device includes a box that includes a heating body incorporating an evaporating chamber and a thermal chamber which are contiguous and separated by a common wall. The thermal chamber hot sea water coming out of a cooling circuit of an engine to flow therethrough via an accelerating pump mounted on an evacuation pipe of the cooling circuit. The heating body is made of a material that resists corrosive action of sea water.

Liquefied gas evaporating device for marine engines, making it possible to supply sea water-cooled boat engines with liquefied petroleum gas (LPG), whether they are inboard, Z-drive or outboard four-stroke or two-stroke engines with pressurized lubrication circuit, this device being constituted of a box (1) comprising a heating body (2) incorporating an evaporating chamber (3) and a thermal chamber (4) which are contiguous and separated by a common wall (5),
- characterized in that the thermal chamber (4) allows therethrough the hot sea water coming out of the cooling circuit of the engine (7, 9) due to an accelerating pump (14) mounted on the evacuation pipe (10) of said cooling circuit, between said engine and said thermal chamber, the heating body (2) being made of a material resisting the corrosive action of the sea water.
A liquefied gas evaporating device for supplying liquefied petroleum gas to a marine engine, comprising:
- a heating body incorporating an evaporating chamber and a thermal chamber;
- the evaporating chamber and the thermal chamber being contiguous and being separated by a common wall;
- the thermal chamber allowing hot sea water to flow therethrough;
- the hot sea water being pumped from a cooling circuit of the marine engine via an accelerating pump mounted on an evacuation pipe of the cooling circuit;
- and
- the heating body being made of a material that resists corrosive action of sea water.
A system for supplying liquefied petroleum gas to a marine engine, comprising:
- a heating body that includes an evaporating chamber and a thermal chamber;
- a wall that is common to the evaporating chamber and the thermal chamber;
- the thermal chamber having an inlet which receives hot water from a cooling circuit of an engine and an outlet which discharges the hot water;
- the evaporating chamber having an inlet which receives gas from a supply reservoir and an outlet which is coupled to the marine engine;
- a pump mounted on an evacuation pipe of the cooling circuit, the pump delivering the hot water to the inlet;
- and
- the heating body being made of a material that resists corrosive action of the hot water.

- a heating body that includes an evaporating chamber and a thermal chamber;
- a wall that is common to the evaporating chamber and the thermal chamber;
- the thermal chamber having an outlet and an inlet which receives marine water;
- the marine water being taken from a marine environment, heated by the marine engine and delivered to the outlet of the thermal chamber;
- the evaporating chamber having an inlet which receives gas from a supply reservoir and an outlet which is coupled to the marine engine;
- a pump that delivers the marine water to the inlet of the thermal chamber;
- and
- a discharge conduit that removes the marine water from the outlet of the thermal chamber to the marine environment,
- wherein the heating body is made of a material that resists corrosive action of the marine water.
