Abstract: A direct injection fuel system is shown for injecting hydrogen fuel into a gas turbine combustor. The fuel injection system includes a plurality of fuel injector blocks. Each fuel injector block includes a fuel admission duct having an inlet for receiving hydrogen fuel from a fuel supply, an outlet for delivering hydrogen fuel into the combustor and a central axis extending from said inlet to said outlet. Each fuel injector block also includes an air admission duct located around the periphery of the fuel admission duct, having an inlet for receiving air from a diffuser and an outlet for delivering air into the combustor for mixing with the hydrogen fuel.

Abstract: A direct fuel injection system (206) is shown for injecting hydrogen fuel into a gas turbine combustor, the fuel injection system comprising a plurality of fuel injector blocks (1202). Each fuel injector block includes one or more air admission ducts (1603) for receiving air from a diffuser and an air outlet for delivering air into a mixing zone for combustion with fuel. Each fuel injector block also includes a fuel admission duct or aperture having a fuel inlet for receiving fuel (F) from a manifold, and a fuel outlet for delivering fuel into the mixing zone.

Abstract: An apparatus for imparting an organoleptic quality to a recipient product using a sensate substance obtained from a donor product, the apparatus comprising a donor product storage chamber; and a recipient product storage chamber, the apparatus being arranged to allow a fluid to circulate repeatedly between the donor product storage chamber and the recipient product storage chamber so that at least one sensate substance obtained from the donor product is conveyed from the donor product storage chamber into the recipient product storage chamber and into contact with the recipient product.

Abstract: An method for imparting an organoleptic quality to a tobacco industry product using a sensate substance obtained from a donor product, the method comprising repeatedly circulating a fluid in a closed loop through a donor product storage chamber containing a donor product and a recipient product storage chamber containing a batch of tobacco industry product so that at least one sensate substance obtained from the donor product is conveyed from the donor product storage chamber into the recipient product storage chamber and into contact with the tobacco industry product to impart an organoleptic quality thereto.
