Gasifier monitor and control system

摘要

A system, including a gasifier comprising a wall defining a chamber, an inlet, an outlet, and a port, a combination feed injector coupled to the inlet, wherein the combination feed injector is configured to inject a first fuel and air or oxygen into the chamber to preheat the gasifier, and the combination feed injector is configured to inject a second fuel and oxygen into the gasifier after preheating to gasify the second fuel, an optical device coupled to the port, a sensor coupled to the optical device, and a monitoring system coupled to the sensor, wherein the monitoring system is configured to acquire data from the sensor, process the data, and provide an output representative of a condition of the gasifier based on the data.

1. A system, comprising:
a gasifier comprising a wall defining a chamber, an inlet, an outlet, and a port; a combination feed injector coupled to the inlet, wherein the combination feed injector is configured to inject a first fuel and air or oxygen into the chamber to preheat the gasifier, and the combination feed injector is configured to inject a second fuel and oxygen into the gasifier after preheating to gasify the second fuel; an optical device coupled to the port; a sensor coupled to the optical device; and a monitoring system coupled to the sensor, wherein the monitoring system is configured to acquire image data that represents a portion of the gasifier from the sensor, process the image data, compare the image data to baseline image data of a throat, and provide an output representative of a condition of the gasifier based on the comparison of the image data to the baseline image data, wherein the image data indicates a change in a size of the outlet relative to the baseline image and the change in size is indicative of a wear condition or a slag condition.
