INSTRUCTIONS:

  1. Enter the boiler operating parameters. Note the units used!
    (1 ton_steam/h = 1,000 kg_steam/h)

  2. Enter the boiler feedwater parameters.
    (Temperature measurement point of the feedwater: at the deaerator tank, feedwater tank, or on the feedwater line before entering the boiler.
    Typically from 25 °C to 105 °C)

  3. Enter the fuel calorific value.
    (Use the working calorific value — Net calorific value / LHV).
    Refer to calorific values of some biomass types here:

  4. Enter the boiler efficiency.
    (Usually from 70% – 90%)

  5. Check the results!

Note: If you need to save the fuel information used for the calculation, enter the fuel name and fuel moisture, then record it with a photo for storage.

OTHER EXTENSION APPLICATIONS:

1. Convert boiler efficiency when you know the fuel consumption on output: Enter the working parameters as input to the furnace, enter the boiler efficiency and change until it matches the standard. Actual loss of the furnace. Then the actual furnace performance can be referred to at the time of consummation.

2. Convert the reference calorific value of the fuel when the furnace efficiency is known: Once the normal efficiency of the furnace in the most optimal operating state is known, enter the input parameters of the furnace. Change the calorific value of the fuel until consumption coincides with reality. Then the fuel heat value can be referenced when it coincides with the actual consumption.

3. Other applications can be referred to when changing the feed water temperature affects boiler consumption.

Note: Fuel heating value cannot be uniform in the test sample and the entire fuel, furnace performance may fluctuate due to other factors, so the extended test value is for reference only!.
