Abstract

A method for recording changing boiler conditions over time in three spatial dimensions including: sensing the boiler conditions in real time using sensors which traverse the combustion chamber and gas path generating data from a plurality of positions in one or more supervisory spaces of interest within the boiler system; transmitting the generated data to a computer system; presenting data containing sensor position information and which optionally contains temperature, chemical species information, and other combustor condition information for delivery to a boiler management system to enable said boiler management system to make real time operational adjustments.

Claims

an un-tethered sensor arranged to travel along a substantially ballistic trajectory within a combustion chamber during operation of the combustion chamber;

said sensor measuring conditions dynamically while traveling along the trajectory within the combustion chamber; and

said sensor communicating the measured conditions wirelessly to an external receiver.

2. The system of claim 1, wherein the un-tethered sensor communicating the measured conditions in real time during travel within the combustion chamber.

3. The system of claim 1, wherein the sensor being at least partly protected by thermal insulation.
