AUTOMATED CONTROL SYSTEM FOR MANAGING MULTIPLE ENERGY SOURCES

摘要

An automated control system (10) for a dual-fuel boiler, engine, or other apparatus (12), is operative for continously monitoring the consumption of a primary fuel source and for automatically switching from the primary fuel source (16) to a secondary fuel source when a predetermined amount of the primary fuel is used in a measured time period, the object of the system being to automatically maintain a 100 % load factor of the primary fuel source based on the measured time period. The system includes a meter (30) for continuously monitoring consumption of the primary fuel and outputting an electronic flow signal representing consumption of primary fuel. The flow signal is received by a programmable logic controller (36) having a real-time clock whereby consumption of the primary fuel is measured against time.
