Abstract
A flame arrester for a process device is provided. The flame arrester includes a flame arrester element formed of a first helix having a first axis and a second helix having a second axis, wherein the first axis and the second axis are unparallel. A housing configured to mount to the process device. The flame arrester element is mounted to the housing. A combustion analyzer employing an improved flame arrester is provided along with a method of manufacturing an improved flame arrester for process devices.
Claims16
A flame arrester for a process device, the flame arrester comprising:
- a flame arrester element formed of a first helix having a first longitudinal axis and a second helix having a second longitudinal axis, wherein the first longitudinal axis and the second longitudinal axis are unparallel;
- a housing configured to mount to the process device, the housing having the flame arrester element attached thereto.
A combustion analyzer comprising:
- a probe body having an oxygen sensing cell disposed therein, the probe body having a distal end with a flame arrester attached thereto, the flame arrester being configured to be interposed between a process gas and the oxygen sensing cell, the flame arrester having a flame arrester element formed by a pair of cross-helixes, each of the pair of cross-helixes having a longitudinal axis that is unparallel to a longitudinal axis of the other;
- and
- a housing coupled to the probe body and having electronics therein, the electronics being coupled to the oxygen sensing cell and configured to generate an oxygen output indicative oxygen concentration in the process gas.
