Description
Technical field
In the boiler cold-state ventilation experiment project that the utility model carries out during power industry power plant boiler is debugged
It is used in primary air piping leveling pilot project.
Background technique
The fixation of sampler is always to influence the problem of in-site measurement accuracy when boiler cold-state ventilation experiment, either
Using Pitot tube, portable anemobiagraph, multichannel measuring wind speed element, there is a problem of what sampling probe positioning was not allowed.This dress
The advantages of setting is: 1. accurate positionings, can guarantee the accuracy of measurement in each dimension of air-flow.2. favorable sealing property,
No matter under cold conditions dust-contained airflow or the hot lower two phase flow with coal dust can guarantee not leak tightly.
The principle of measuring wind speed is as follows:
Q=3600Av m3/h
In formula:
K --- test the speed tube cofficients；
A --- duct cross-section product, m2；
Pd--- air-flow is averaged dynamic pressure, Pa；
ρ --- current density, kg/m3；
V --- wind speed m/s
Q --- air quantity m3/h
In formula:
ρ0--- gas density under standard state, kg/m3；
T --- gas temperature, DEG C；
pact--- local atmospheric pressure, Pa；
ps--- gas-static in managing, Pa.
Currently, primary air piping leveling is a Xiang Fei when heat power plant boiler debugs stage boiler cold-state ventilation experiment
The more accurate pilot project of normal important and technical requirements.But its specific measurement means is continued to use always engineered form and is carried out, but
In manual measurement data procedures, it is mingled with some human body instincts unavoidably to the influence factor of measurement result.Such as: employment hand handle is held
When the measuring rod (probe) or Pitot tube measuring rod of anemobiagraph, to maintain a posture for a long time it is motionless be it is absolutely not,
But once human body movement will change position or the angle of measuring probe, and the accuracy of measured parameter just will receive shadow
It rings, biggish deviation may occur in measured data under the same operating condition.
