Integrated sensor system and methods for combustion processes

An integrated sensor system for use in a furnace system including a furnace having at least one burner and two or more zones each differently affected by at least one furnace parameter regulating energy input into the furnace, including a first temperature sensor positioned to measure a first temperature in the furnace system, a second temperature sensor positioned to measure a second temperature in the furnace system; and a controller programmed to receive the first and second measured temperatures, and to adjust operation of a furnace system parameter based on a relationship between the first and second temperatures, thereby differentially regulating energy input into at least two of the zones of the furnace; wherein the relationship between the first and second temperatures is a function of one or more of a difference between the two temperatures, a ratio of the two temperatures, and a weighted average of the two temperatures.

PROCESS CONTROLLER HAVING ADJUSTABLE PARAMETERS
20240319682 · 2024-09-26 · ·

Automatically generating a compensation factor for adjusting an operating parameter such that a measured carbon potential, dew point, or other controlled parameter matches the controller's set point value by inputting the measured parameter directly to the controller.

Method and apparatus for improving furnace temperature uniformity

A method includes firing a first burner into a furnace process chamber in a first initial condition, firing a second burner into the process chamber in a second initial condition, and measuring temperature at each of an array of locations in the process chamber. The first burner is adjusted to a first adjusted condition while the second burner is being fired at the second initial condition, and a resulting first temperature change is measured at each of the locations. The second burner is adjusted to a second adjusted condition while the first burner is being fired at the first initial condition, and a resulting second temperature change is measured at each of the locations. The measured first and second temperature changes are recorded as reference data for adjusting burner conditions to adjust temperatures at each of the locations. The method can thus be used to improve temperature uniformity throughout the array of locations.

ROTARY FURNACE DIRECTIONAL FLUID CONDUIT HEAT CONTROL SYSTEM
20240384933 · 2024-11-21 · ·

A directional fluid heat control system for a high temperature kiln with a process zone. The system includes two rigid, coaxially aligned tubes positioned in the kiln. One tube rotates inside the other. One tube has a series of longitudinal openings, while the other has a series of helically arranged openings. Rotating one tube selectively aligns an opening from that tube with an opening in the other. Further rotation aligns different such pairs of openings with different longitudinal orientations in the kiln. The aligned openings release pressurized fluid from the inner tube into desired locations in the kiln's process zone.

System, method and device for temperature control

A method for temperature control includes: acquiring the present temperature of a reaction window in a process chamber of a semiconductor machine; comparing the present temperature with the preset temperature to acquire a comparison result; and adjusting the exhaust amount of an exhaust passage of the process chamber based on the comparison result to control the temperature of the reaction window.
