Abstract:
A method and at least one steam aspirating gas flare for carrying out the method are disclosed for smokeless burning of undesired gas. The flare includes a steam control valve responsive to a new very low gas flow detector utilizing a knockout drum water seal, a by-pass line with an orifice run, and a water level switch for supplying an empirically set fixed flow of steam to the flare for ensuring a smokeless flame prior to the gas flow rate reaching a measurable rate. A full range flare including all other gas flows includes also several steam flow valves, each valve being empirically set to provide the proper steam-to-gas ratios throughout its respective range responsive to several corresponding gas flow detectors for ensuring a smokeless flare as the flare gas flow varies from the immeasurable ranges through the measurable ranges of the detectors.
Abstract:
A method and at least one gas flare for carrying out or practicing the method are disclosed for smokeless burning of undesired gas. The new full range, high capacity steam aspirating gas flare comprises a steam control system responsive to the new very low gas flow detector utilizing a knockout drum water seal having an end of the main line submerged therein with two bypass lines around the main line end for detecting various gas flows in the unmeasurable ranges below 3 percent of the maximum design gas flow and for controlling steam flow to the flare (1) to insure a smokeless flame and (2) to provide high savings in steam usage.
Abstract:
A method and at least one gas flare for carrying out or practicing the method are disclosed for smokeless burning of undesired gas. Combined with a steam aspirating gas flare having a steam flow controller responsive to a gas flow detector to provide a combustible material is a specific gravity analyzer for controlling the steam flow controller further in relation to the specific gravity of the gas to be burned for providing a smokeless air-to-gas burning mixture in the flare with less steam usage and reduced noise.
