Abstract

A remote burner monitoring system including one or more burners each including integrated sensors, a data collector corresponding to each of the burners for receiving and aggregating data from the sensors of the corresponding burner, and a local transmitter corresponding to each of the data collectors for transmitting the data, a data center configured and programmed to receive the data from the local transmitters corresponding to the one or more burners, and a server configured and programmed to store at least a portion of the data, to convert the data into a display format, and to provide connectivity to enable receipt and transmission of data and the display format via a network including at least one of a wired network, a cellular network, and a Wi-Fi network.

First claim

The invention claimed is:

1. A remote burner monitoring system comprising:
one or more burners mounted in a furnace, each burner including:
integrated sensors; and
an instrument enclosure positioned toward a rear of the burner distal from the furnace, the instrument enclosure containing:
a data collector corresponding to the burner for receiving and aggregating data from the integrated sensors of the burner, and
a local transmitter for transmitting the data aggregated by the data collector;

a data center configured and programmed to receive the data from each of the local transmitters; and
a server configured and programmed to store at least a portion of the data, to convert the data into a display format, and to provide connectivity to enable receipt and transmission of data and the display format via a network including at least one of a wired network, a cellular network, and a Wi-Fi network;
wherein the data collector of each of the burners is programmed to provide power to individual sensors only when data is to be collected, based on one or both of a combination of sensed data and a periodic schedule, and taking into account the specific requirements of each of the individual sensors.

2. The system of claim 1 , further comprising:
a computer configured and programmed to transmit and receive data to and from the network.

3. The system of claim 1 , wherein the data center includes one or more of a data receiver for receiving the data, a server for storing at least a portion of the data, and a router for providing connectivity to enable network receipt and transmission of data.

4. The system of claim 1 , wherein the data collector of each of the burners is programmed to provide a correct voltage to each of the integrated sensors of the burner.

5. The system of claim 1 , wherein the local transmitter corresponding to each of the burners transmits data wirelessly, either directly to the receiver server or indirectly via one or more Wi-Fi repeaters, as required by the distance and signal path between the burner and the receiver server.

6. The system of claim 1 , wherein the display format is selected from the group consisting of: an Internet web page format and a mobile device app format.

7. The system of claim 1 , wherein the data collector corresponding to each burner is powered by local energy harvesting.

8. The system of claim 1 , wherein at least one of the burners uses an oxidant selected from the group consisting of: air, oxygen-enriched air, industrial grade oxygen, and combinations thereof.

9. The system of claim 8 , wherein at least one of the burners is configured to combust a fuel selected from the group consisting of: gaseous fuel, liquid fuel, solid fuel, and combinations thereof.

10. The system of claim 8 , wherein at least one of the burners is configured to perform staged combustion.

11. The system of claim 1 , wherein the server is integrated with the data center.

12. The system of claim 1 , wherein the server is located in the cloud.

13. A method of monitoring operation of one or more burners, the method comprising:
sensing operational data at each of the burners;
locally collecting the data at each of the burners via a corresponding data collector mounted in an instrument enclosure on each of the burners;
transmitting the collected data from each of the burners to a data center via a corresponding transmitter mounted in the instrument enclosure corresponding to the data collector for each said burner;
converting the data into a display format;
transmitting the display format via a network including at least one of a wired network, a cellular network, and a Wi-Fi network; and
providing power to individual sensors sensing the operational data only when the data is to be collected, based on one or both of a combination of sensed data and a periodic schedule, and taking into account the specific requirements of each of the individual sensors.

14. The method of claim 13 , wherein converting the data into a display format comprising serving up the data in one or more of an Internet web page format and a mobile device app format.

15. The method of claim 13 , further comprising:
transmitting the collected data from the data center via the network to the cloud;
storing the collected data in a remote data repository; and
enabling access via the network to the collected data stored in the remote data repository.

16. The method of claim 13 , further comprising:
analyzing the collected data including performing statistical analysis of the collected data corresponding to one of the burners, performing comparative analysis of the collected data between two or more of the burners, comparing the collected data for one or more of the burners to preset alarm setpoints and generating alarms, and combinations thereof.

17. The method of claim 13 , further comprising:
controlling operation of the one or more burners based on the collected data and analysis of the collected data;
wherein controlling operation includes one or more of maintaining burner operating parameters within prescribed limits, tuning local flame characteristics, and rapidly responding to adverse burner conditions.

18. The method of claim 17 , wherein the adverse burner conditions include one or more of an elevated temperature of a burner component, an elevated temperature of a furnace component, and flame instability.
