Abstract
A vaporizer for vaporizing a liquefied gas includes a first heat exchanger block having first and second linear conduits extending therethrough, a second heat exchanger block having first and second linear conduits extending therethrough, one or more heaters located between the first and second heat exchanger blocks, and an inlet capacity control valve. The heat exchanger blocks may be fabricated by extruding aluminum. The heaters may be independently powered. At least a portion of the inlet capacity control valve may be located within one of the conduits.
Claims15
A method, comprising:
- fabricating a heater assembly for heating a liquefied gas, the heater assembly comprising:
- a heat exchanger block having a first end, a second end, and at least two parallel linear conduit passages that are offset from each other and extend from the first end to the second end;
- and
- a positive temperature coefficient heater configured to heat the heat exchanger block, wherein the positive temperature coefficient heater includes first and second conductive plates and a plurality of positive temperature coefficient heating stones in electrical contact with the conductive plates in an electrically parallel configuration;
- wherein fabricating the heater assembly includes extruding the heat exchanger block as a single piece of aluminum, whereby the at least two parallel linear conduit passages are integrally formed in the heat exchanger block during the extruding, and thereafter removing material of the heat exchanger block between the at least two parallel linear conduit passages to connect the at least two parallel linear conduit passages together.
