SST Sensing's OXY-GAP-100 Gas Analyzer Probe is designed to measure up to 25% oxygen content at temperatures up to 1292°F (+700°C) within flue or stack gases making it a complete solution for combustion optimization and burner/boiler trim applications.
Jun 01, 2020 · The airflow switch is a burner/boiler safety device that proves (makes sure) that the combustion blower is running and providing the minimum amount of air pressure for safe light off, before we try to light off the burner. Not only is it used to prove things like air or water flow, but we also use it …

The present techniques are directed to a system and methods for operating a gas turbine system. An exemplary gas turbine system includes an oxidant system, a fuel system, and a control system. A combustor is adapted to receive and combust an oxidant from the oxidant system and a fuel from the fuel system to produce an exhaust gas. A catalyst unit including an oxidation catalyst that includes
Oct 12, 2016 · Boiler burners use combustion to produce heat to make hot water or steam. In the process, nitrous oxide or NOx is produced as a byproduct of combustion. This pollutant can have harmful effects on the environment and is a large contributor to particulate matter, ozone, and acid rain.
Model CBLE 125-800 HP Boilers 4 Rev. 2 13 FEATURES AND BENEFITS The Cleaver-Brooks Model CB Boiler - the premium firetube on the market today - includes the four-pass dryback design, five square feet of heating surface per boiler
This may be the rated steam flow, but instead, you may hit some other limit first-running out of air, boiler feedwater (BFW), too high temperature somewhere, and so on. Sometimes you reach a point of diminishing return; if the steam flow has been increasing by 5% every time you open the fuel valve 3% to 4% all along, but it takes a 6% fuel
CC-700 – BOILER MASTER CONTROL WITH OXYGEN TRIM. This control combines all features of the Century Boiler Master Control and the Oxygen Trim Control. This system brings it all together, allowing you optimal boiler room efficiency. If reducing greenhouse gas emissions is …
Feb 01, 2014 · After condensing the steam, the best method to improve steam system efficiency is to return the maximum quantity of condensate to the boiler plant for reuse in the production of steam. Steam traps are automatic valves that remove air, condensate, and noncondensable gases from steam piping or steam utilization equipment while preventing steam loss.
May 27, 2020 · An oxygen analyzer measures the para-magnetism of air. The air being measured for oxygen is filtered by passing it through a diffuser before. Then it is
In its dissolved form, oxygen is highly corrosive to most metals, especially the mild steel used for boiler tubes. One way to do this is by dosing the boiler feedwater with hydrazine. Hydrazine is a colorless liquid that is highly soluble in water. It is a powerful reducing agent and reduces oxygen to form

Dec 27, 2013 · It's got all the bells and whistles, FGR, linkage-less actuators set up using a combustion curve, and an O2 sensor in the stack. The problem is, it's out of calibration by about 2% lower than my analyzer, which was just calibrated by the Testo factory. If I set the O2 up properly via my analyzer, the boiler trips on low O2 alarm (1.5%).

Feb 25, 2004 · Boiler drum-level control is critical. Too low a level may expose boiler tubes, which overheats and damages them. Too high a level may interfere with separating moisture from steam, which reduces boiler efficiency and carries moisture into the process or turbine. The drum-level controller maintains the level at constant steam load.
5.11 Two Boiler Lead Lag The Hawk 1000 uses dual setpoints to accomplish "Lead Lag" control in a two boiler control scheme. The setpoints are based on each boiler's local steam pressure (for steam boilers). The "Master" boiler has a selector switch, which designates each of the two boilers as lead, or lag.
