Abstract
A quartz heater is provided for heating fluids or objects. The heater comprises a member, for example, a quartz glass tubular or non-tubular member, with a low-emissivity conductive coating that produces heat when connected to external power. The fluid can be heated as it passes through the tubular member. If the member is not completely coated, then heat radiates toward the center of the member, pass through its uncoated portion, and then onto objects for heating.
Claims16
A heating element, comprising:
- a member having a major surface;
- a conductive coating disposed on at least a portion of the major surface of the member;
- and
- annular connections disposed onto and in electrical contact with the conductive coating, the annular connections defining contiguous annular heating sections that are only electrically parallel to one another, such that for a given voltage and size of the member, the heat generated is directly proportional to the number of the contiguous annular heating sections.
