Novel velocity control device for a burner using bimetallic materials for preheated fuel and oxidizer

A system for controlling jet velocity of a gas, comprising:

• a source of oxidizing gas;
• a source of fuel gas;
• at least one temperature-sensitive bimetallic valve in connection with one of the source of oxidizing gas or the source of fuel gas, the valve comprising a bimetallic strip, a blocking device and a flow control structure and configured to:
• receive an oxidizing gas or a fuel gas, wherein the oxidizing gas or the fuel gas is at a first temperature;
• change the temperature of at least the bimetallic strip from a second temperature to the first temperature;
• change position of the bimetallic strip, as measured from the flow control structure, in response to the change in temperature from the second temperature to the first temperature;
• and
• change the velocity of the oxidizing gas or the fuel gas through the valve based on the position of the bimetallic strip;
• and
• a burner configured to:
• receive an oxidizing gas or a fuel gas from the at least one temperature-sensitive bimetallic valve, wherein the oxidizing gas or the fuel gas is at the first temperature;
• combine and combust the fuel gas with the oxidizing gas to create a flame;
• and
• direct the flame to a target material.
