Abstract
A microprocessor-based controller manages delivery of BTUs or power by determining an amount of thermal heat or power needed through sensors and, in response, controls a batch or continuous feed of biofuel fuel and/or air to a biofuel furnace. The controller controls the fuel and air required to operate the furnace efficiently.
