* Calorific Value: also called specific heat of combustion. It represents the amount of
heat released when a given amount of fuel is burned completely. The calorific value is
expressed as calories (or kilocalories) per unit weight of fuel.
* Polegada: unit of length used in the British imperial system of measurements. One inch
is 2.54 centimeters or 25.4 millimeters.
* Rated power: Electrical power consumed from the power source. It is indicated in watts.
* Nominal heat output: heating capacity, i.e. the heat transfer that the equipment will
make of the energy of the firewood – is measured for a standard firewood load in a given
period of time.
* Power of use: it is a recommendation of the manufacturer testing the equipment with
loads of firewood within the reasonable parameters of minimum and maximum operation
of the equipment. This minimum and maximum power of use will have different firewood
consumption per hour.
* Yield: is expressed as the percentage of "useful energy" that can be extracted from a
given system, taking into account the "total energy" of the fuel used.
* Ignition temperature: temperature above which the fuel can combust.
* Thermo-resistant: resistant to high temperatures and thermal shock.
* Vitroceramic: high strength ceramic material produced from the controlled
crystallization of glassy materials. Widely used for industrial applications.
* W (Watt): the International System (SI) unit for power.
