Intelligent Temperature Controller for Biofuel-Fired Burner

A bio-fuel fire control system comprising:

• a first port configured to be coupled to a temperature sensor and to receive from the temperature sensor a signal indicating a temperature of exhaust gas from a bio-fuel fire;
• a second port configured to be coupled to an air handler that supplies air to the bio-fuel fire and to supply to the air handler a control signal that controls a rate at which the air handler supplies air to the bio-fuel fire;
• and
• a controller coupled to the first and second ports and configured to automatically:
• repeatedly receive, via the first port, the signal indicating the temperature of the exhaust gas, thereby receiving a series of temperature level samples;
• and
• for each temperature level sample of at least some of the series of temperature level samples:
• compare the temperature level sample to a first predetermined value;
• and
• when, as a result of the comparison, the temperature level sample is found to be less than the first predetermined value:
• generate a control signal configured to cause the air handler to increase the rate at which the air handler supplies air to the bio-fuel fire;
• and
• send, via the second port, the generated control signal to the air handler.
