What methods is everyone using to measure coal consumption in the coal feeding system of boilers? If I don’t want to use electronic belt scales, are there any other good alternatives? Those who know about this, please share your insights
Solid flow meters: paddle, microwave, radiation, and so on
Reply to 2# jessehjx: Could you go into more detail?
Have heard of solid powder flow meters.
There are now solid mass flow meters. But there must not be too large solid lumps! You can also choose a zero-gravity scale
An impulse-type solid flow meter is a type of flow meter that measures the flow rate of freely falling granular materials based on the principle of momentum. It converts the force generated by the impulse of the material being measured and the force produced as the material slides downward on the sensing plate into a standard DC signal proportional to the instantaneous weight (0–10mA or 4–20mA). The solid flow meter (hereinafter referred to as the flow meter) can directly output a standard DC current signal with the support of a 24V·DC power supply. When used in conjunction with an intelligent flow indication and accumulation instrument, it enables the indication of the flow rate of the medium being measured, as well as its accumulation. It can also be used together with other instruments for tasks such as recording and quantitative control. This type of flow meter is particularly suitable for computer-controlled applications, offering a simple structure and high reliability. Flow meters can continuously measure the flow rate of granular media under sealed conditions, and they are widely used in industries such as petrochemicals, cement, power generation, mining, food processing, refining, and light industry.

Personally, I think weight scales should have higher accuracy. I wonder if anyone here has experience using them in this regard?
I once used a nuclear balance to measure solid powders, and the results were excellent. It’s just a bit more expensive, and after purchasing it one has to go to the public security bureau to register it, which is quite troublesome.
