Droplet generator assembly and method of replacing components

A system, comprising:

• a droplet generator assembly;
• a service valve coupled to the droplet generator assembly and coupled to a gas vacuum delivery system, and wherein, when the service valve is in an opened position, a gas is introduced into the droplet generator assembly, and, when the service valve is in a closed position, the gas is prevented from being introduced into the droplet generator assembly;
• an isolation valve coupled to the droplet generator assembly and in fluid communication with the service valve through the droplet generator assembly, and the isolation valve in fluid communication with a liquid fuel transfer assembly;
• a pressure sensor coupled to the isolation valve, the pressure sensor is configured to, in operation, measure a pressure within the isolation valve and output a signal;
• a control device coupled to the pressure sensor, the control device is configured to, in operation, receive the signal output by the pressure sensor;
• a temperature adjustment module coupled to the control device, and the temperature adjustment module is configured to, in operation, reduce a temperature of the isolation valve.

A system, comprising:

• a droplet generator assembly having a first side and a second side opposite the first side;
• a service valve with a first orifice at the first side of the droplet generator assembly;
• an isolation valve with a second orifice at a second side of the droplet generator assembly;
• a temperature adjustment module in proximity to the isolation valve and configured to, in operation, reduce a temperature of the isolation valve;
• a nozzle at an end of the droplet generator assembly, the nozzle in fluid communication with the service valve and the isolation valve through the droplet generator assembly;
• a service pathway extends through the droplet generator assembly and extends from the first orifice of the service valve to the second orifice of the isolation valve;
• an operation pathway extends through the droplet generator assembly and extends from the second orifice of the isolation valve to the nozzle at the end of the droplet generator assembly;
• a liquid fuel transfer assembly in fluid communication with the isolation valve, the liquid fuel transfer assembly is configured to, in operation, introduce a liquid fuel into the droplet generator assembly through the second orifice of the isolation valve.
