SYSTEMS AND METHODS FOR HEATING WATER USING BIOFUEL |
摘要 |
The present invention may be embodied as a biofuel heating system comprising a controller for operating a fan based on a load operating parameter such that air flows along a flow path extending through a combustion chamber, through a burn-out port, through a burn-out chamber, through a heat exchange port, through a heat exchange chamber, and out of an exhaust port. A heat exchange system transfers heat energy from air flowing through the heat exchange chamber to a working fluid. The controller operates in a char mode based at least in part on the load operating parameter, and the biofuel remains within the combustion zone during the char mode. |

1. A biofuel heating system for converting biofuel to heat energy to be delivered to a working fluid for transferring heat to a load formed by at least one of a domestic hot water system and a domestic space heating system, comprising:
a combustion chamber; a burn-out chamber; a burn-out port arranged to allow fluid to flow out of the combustion chamber and into the burn-out chamber; a heat exchange chamber; a heat exchange port arranged to allow fluid to flow out of the burn-out chamber and into the heat exchange chamber; an exhaust port arranged to allow fluid to flow out of the heat exchange chamber; a heat exchange system arranged at least partly within the heat exchange chamber, where the working fluid is circulated between the heat exchange system and the load; a fan arranged to cause fluid to flow out of the heat exchange chamber through the exhaust port; at least one load sensor configured to sense a load operating parameter corresponding to a working fluid temperature of the working fluid after the working fluid returns from the load to the heat exchange system; and a controller for operating the fan based on the load operating parameter such that air flows along a flow path extending through the combustion chamber, through the burn-out port, through the burn-out chamber, through the heat exchange port, through the heat exchange chamber, and out of the exhaust port; whereby the heat exchange system transfers heat energy from air flowing through the heat exchange chamber to the working fluid; and the controller operates in a char mode based at least in part on the load operating parameter, where the biofuel remains within the combustion zone during the char mode. |
