Abstract

The energy evaluation of the cooking process of a Hoffman kiln was carried out at the Ocaña brickworks, through a virtual instrument with Lab View software using temperature sensors and data acquisition cards, which allowed the temperature monitoring and recording generating temperature profiles; then, we evaluated the amount of total heat added by the fuel and the heat loss present in the masonry, the material to be cooked, the moisture from the material, the chemical decomposition of clay, the moisture in coal, the water produced in the combustion, the air humidity, the unburned, the walls and the smoke, as well as the energy efficiency of the kiln and the yield per amount of cooked material.
