Does the type of fuel (diesel or natural gas) affect the calculated capacity?
The type of fuel does not directly affect the thermal capacity of the boiler (kcal output), but it affects the required input power of the burner and the operating cost, because the heating value of the fuels is different.
What is meant by the reliability factor (SF) in capacity measurement What is it?
The safety factor is a margin to compensate for uncertainties, loss of efficiency during the life of the device or temporary unforeseen needs (such as starting work at a very low ambient temperature).
What happens if we buy a boiler larger than the required capacity? Cycling). This reduces the efficiency, increases the wear of the burner parts and leads to carbon deposition in the coils.
