Description

Auxiliary tool for accurately measuring gas concentration of boiler furnace

Technical Field

The utility model belongs to the technical field of detection of gas concentration of a boiler furnace, and particularly relates to an auxiliary tool for accurately measuring the gas concentration of the boiler furnace.

Background

A boiler using single gas or mixed gas such as blast furnace, converter, coke oven gas and natural gas as fuel needs to detect whether the gas concentration in a hearth is within a specified range before the boiler is ignited, so that the condition of explosion accidents caused by the exceeding of the gas concentration is prevented. The gas concentration monitoring operation before the ignition of the existing boiler is as follows, a CO alarm or a four-in-one alarm is fixed on the top of an iron long rod by using an iron wire, then a detection instrument penetrates into the 2-3m position of the hearth from a fire observation hole of the hearth, the long rod is taken out after standing for 10 seconds, and the gas concentration value is checked to be used as the basis for whether the ignition of the boiler in the next step is carried out. The operation mode is that the read data are not real-time data because the read data are contacted with air when the long rod is taken out, the read data can not be completely used as the basis of whether the concentration of the combustible gas reaches the standard before the boiler is ignited, and meanwhile, the CO alarm or the four-in-one alarm is fixed on the top of the long rod by using an iron wire, so that the alarm falls off.

The patent of application number 202220491796.5 discloses a gas boiler with gas concentration detection effect, through exhaust tube, collection jar, blending tank and the driven gear that set up, when carrying out concentration detection to the inside gas of gas boiler, respectively through the exhaust tube extraction gas of different co-altitude enter into collection jar, enter into the blending tank through collection jar, drive the driven gear through motor drive driving gear and begin to rotate for the blending tank rotates constantly, and the mist detects gas, improves detection accuracy. This patent cost is higher, need set up a plurality of jar bodies, equipment and detect, not only need throw in more funds, need the continuous maintenance in later stage moreover, further increased use cost.
