METHODS AND APPARATUS FOR CONTROLLING BAKING OVEN ZONE TEMPERATURE

摘要

Apparatus and methods for controlling temperature in a bakery oven zone wherein a predetermined temperature is selected and fuel and pressurized combustion air are supplied to burners in such zone. The fuel supplied is a function of the combustion air pressure which may be adjusted in response to the sensing of temperature variations and in such manner as to maintain the predetermined temperature in such zone substantially constant. The pressure of the combustion air also may be varied in such manner as to adjust the number of ignited burners in such zone.
