Methods for super heated steam generation

摘要

Modularized, superheated steam generators comprise a steam module (46), a thermocouple module (41), and an electrode module (45) assembled within a containment enclosure (66). The multi-stage steam module (46) comprises a plurality of first stage pressure vessels (77) surrounding and feeding a second stage pressure vessel (78). The steam module (46) is coaxially surrounded by insulation (48) disposed within a cylindrical shroud (72). The electrode module (45) radiantly heats the steam module with resistive heating elements (119). The thermocouple module (41) includes thermocouples monitoring first stage temperatures within and between pressure vessels (77). PLC computer SCADA software (600) operates the generators. Thermocouple data is analyzed to control heater temperatures, the water feeding system (340), and outputted steam temperature. PLC software (600) provides operating logic (602) establishing a start up subroutine (602), a ramp up subroutine (603), a steady state subroutine (605), and a shut down subroutine (606).

主权项

1. A method for producing superheated steam, the method comprising the steps of :
providing a plurality of pressure vessels; heating the pressure vessels with a plurality of heating elements; sensing temperatures proximate said vessels; providing water to said pressure vessels through a water distribution manifold connected through individual water delivery lines leading to said pressure vessels; feeding water to said water distribution manifold at selectable pressures with a variable pressure system pump; energizing said heating elements during operation of said generator with a power control circuit; operating said variable pressure system pump, and energizing said power control circuit with a PLC computer system; and, discharging superheated steam.
