Abstract: A premix burner made up of an air inlet tube of length L and a single specific gas injection, the gas injection includes an upstream gas injector, a mixer, a downstream gas injection situated at a distance L3 from an upstream end of the air inlet tube and a stabilizing element, where the gas injection constitutes a one-piece mechanical assembly that ensures a self-stable elementary flame.

Abstract: Examples described herein include systems and methods for setting virtual machines (“VMs”) to desired configurations while the virtual machines are running. In one example, a user can select a VM and a desired configuration. An agent can then set an attribute of the virtual machine to indicate that on guest operation system (“OS”) reboot of the VM, the VM will enter BIOS mode. The agent can also store the desired configuration in the database based on authenticating the user. When the VM reboots at a future time, the attribute can cause the VM to enter BIOS setup. The agent can be notified and can retrieve the desired configuration from a database using an identifier for the VM. Then the agent can apply the desired configuration to the VM during BIOS setup with a system process that does not require further user authentication.

Abstract: A burner designed to be fitted in a combustion chamber, the burner including: a central nozzle configured to have an oxidizer and fuel supply; several peripheral nozzles configured to have an oxidizer and fuel supply and which each have at least one upstream fuel injector in order to pre-mix the fuel and the oxidizer in the nozzle; at least one oxidizer input connected to the said central and/or peripheral nozzles; wherein peripheral nozzles each have a flame stabilizer located at the end of the peripheral nozzle designed to exit into the combustion chamber, as well as a tip injector to inject fuel at the end of the peripheral nozzle.
