Steam Dome Patents (Class 122/486)
  • Patent number: 11802648
    Abstract: A steam generator for use with a liner assembly for pipeline repair or reinforcement, includes: a water heater configured to heat water to generate steam; a water feed conduit configured to convey water to the water heater; an air heater configured to generate heated air; an air supply conduit configured to convey pressurized air to the air heater; a heated air supply conduit configured to convey heated air from the air heater to the water heater to yield a steam-air mixture; and an output conduit configured to convey the steam-air mixture from the water heater. An automated steam generator system including the steam generator is also described.

  • Patent number: 5810977
    Abstract: A water purifier which purifies water by superheated steam. The water purifier includes a raw water reservoir for contaminated water; a heater at least partially disposed within the raw water reservoir and including a heat source, an inlet for steam and an outlet for superheated steam; an inlet conduit in fluid communication with the inlet of the heater for transporting steam produced by boiling said raw water; and a condenser in fluid communication with the outlet of the heater. The heater both boils the raw water to produce a substantially saturated steam and superheats the substantially saturated steam. The water purifier can further include a purified water reservoir in fluid communication with the condenser.

  • Patent number: 5467424
    Abstract: Apparatus and method for generating steam free of silica-containing droplets. The apparatus makes use of the fractional distillation properties of water/quartz mixtures. At the moderately high pressures and corresponding boiling temperatures which are used in the apparatus, the steam generated from water containing quartz is considerably purer than the water from which it originated. The apparatus includes a boiler supplied with de-ionized water. The boiler has a steam generating chamber and level indicators to provide sensing of overfill and underfill levels, respectively. Steam passes out of the boiler chamber into and through a large number of small vent holes into another chamber containing quartz pieces. Droplets collect on these quartz pieces and either evaporate or gravitate and return to the boiler chamber. All parts of the apparatus of the apparatus are made of quartz except the dump valve body which is constructed from plastic material.

  • Patent number: 4895136
    Abstract: An improved gas-jet hot water heater system for the generation of high-temperature water at atmospheric pressure simultaneously with superheated water and/or steam. The heater system comprises a primary tank for the generation and storage of high-temperature water. The primary tank includes a combustion zone whereat the products of combustion of a gas-jet burner may heat the water passing therethrough and a storage zone located beneath the combustion zone for receipt and storage of the heated water. A supplemental sub-assembly includes a pressurized remote storage tank, a heat exchanger in the combustion zone for water to being superheated by the products of combustion of the gas-jet burner and conduit means coupling the heat exchanger with the storage tank. The heat exchanger will create and store superheated water in the lower extent of the storage tank and steam in its upper extent. In an alternate embodiment, the output of the heat exchanger may be fed remotely for direct use.
