Feb 02, 2019 What are coal feeders? Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume ...

Feb 23, 2016 With coal, this approach is problematic. According to Schenck, coal density changes with size, moisture and a variety of other factors. Therefore, even if an operation were processing coal of equal dimensions, each piece may have a different density. In light of this reality, gravimetric weigh feeders are the better option.

Jun 30, 2010 The weights must be able to go to at least 80% of the capacity of the installed load cell. The type of calibration and kit will depend on your application and if it is possible to remove the installed load cells or not. Another easy and relative inexpensive way it can be done is to use water bags, because 1 liter of H2O = 1 Kg in weight so 1000 ...
The gravimetric feeder does this by determining the product of the fuel belt load multiplied by the speed to give the actual flow rate (e.g. tons/hr). This flow rate is compared to the boiler set point and the belt speed is varied accordingly: Gravimetric Conversion Scope: Installing a two loadcell weigh suspension with no moving parts, levers ...
Jul 22, 2010 The gravimetric feeder measures the fuel weight over a fixed length of feeder belt, then adjustment to belt speed will provide desired fuel energy input. If the purpose of the calibration is a heat rate test, and particularly for a supplier/customer acceptance test, I would consult the ASME Power Test Codes for any prescribed requirements.
