Abstract: A fuel injector for a gas turbine engine includes a support member and a nozzle tip disposed on the support member with a deformable, removable metallic or non-metallic seal member disposed between facing sealing surfaces of the support member and a shroud member of the nozzle tip. The deformable seal member includes one or more fuel passages through which fuel in one or more fuel circuits flows with the seal member sealingly separating the first and second fuel circuits and preventing external fuel leakage from the nozzle tip. The nozzle tip can include an inner fuel swirler that includes one or more swirler slots wherein each slot is so angled in an axial direction toward the discharge orifice of the nozzle tip assembly that operation of the nozzle tip assembly is unaffected by changes in fuel viscosity.

Abstract: A waste management facility is provided with operational control of a waste mass for optimum hydrogen production. The facility includes an air circulation control facility cooperating with the waste mass, a liquid introduction system cooperating within the waste mass, a monitoring mechanism for optimum operation of the waste management facility, a control mechanism for adjusting air circulation and liquid introduction thereby controlling waste mass temperature and pH to create an environment to deactivate methanogenic bacteria and isolate and maximize the number of hydrogen producing bacteria and a gas collection system for collecting the hydrogen produced by the hydrogen producing bacteria.
