Patent ID: 8388892

Claim:
An in-line loss-on-ignition measurement system comprising: an on-site extractor subsystem configured to collect a fuel or a combustion by-product from a hydrocarbon fuel burning plant; an on-site analyzer coupled directly to the extractor subsystem and configured to receive the collected fuel or the combustion by-product from the extractor subsystem and configured to weigh and burn the collected fuel or the combustion by-product, the on-site analyzer including: a chamber, a platen positioned in the chamber and configured to support and burn the collected fuel or the combustion by-product, a heater disposed within the platen and configured to heat the platen, and a balance connected to the platen; and a controller responsive to the on-site analyzer and configured to determine the loss-on-ignition for the plant based on the weight of the collected fuel or the combustion by-product before and after it is burned on the platen.
