Vacuum spray boiler

A vacuum spray boiler cooling system for cooling a fluid, the system comprising:

• a vacuum tank having an enclosed space at least partially surrounded by a casing;
• components integrated within the vacuum tank, the components comprising:
• a fluid inlet and a fluid outlet penetrating the casing, the fluid inlet and the fluid outlet for carrying the fluid through the casing;
• a heat exchanger in the enclosed space;
• a coolant spray apparatus in the enclosed space, the coolant spray apparatus for spraying coolant onto the heat exchanger;
• and
• a coolant inlet and a coolant exhaust port at least partially penetrating the casing, the coolant inlet for carrying the coolant to the coolant spray apparatus and the coolant exhaust port for carrying vaporized coolant away from the enclosed space;
• and
• an exhaust vent connected to the coolant exhaust port and in thermal contact with a portion of the components, the exhaust vent to release the vaporized coolant from the system.
