- The PV is already cheaper than from fossil fuels - Tool to calculate the electric charges hocatec


Combustion efficiency - Indicates the ability for a burner for burning a fuel measured by the unburned fuel and excess air. Thermal efficiency - Indicates the effectiveness of the heat exchanger to transfer heat from the combustion process water or steam boiler, excluding losses by radiation and convection. Fluid fuel efficiency - Indicates the total efficiency of the boiler including the thermal efficiency of the heat exchanger, radiation and convection losses - output divided by input.
q = exported hocatec heat (kJ / s, kW) m / t = mass flow rate (kg / s) m = mass (kg). T = Time (s) C p = specific heat capacity (kJ / kg C) dT = temperature difference enters the inlet and outlet of the boiler (C).
