  • Apparatus and method for cooling a gas turbine vane
    Patent number: 4962640
    Abstract: An apparatus and method are provided for preventing the plugging of cooling air distribution holes in a hollow gas turbine vane by particles entrained in the cooling air. The portion of the cooling air is bled from the vane and discharged into the hot gas downstream of the vane, the shunted bleed air carrying the entrained particles.
    Type: Grant

  • Turbine combustor having enhanced wall cooling for longer combustor life at high combustor outlet gas temperatures
    Patent number: 4527397
    Abstract: A combustor for a stationary combustor turbine is provided with a generally tubular sidewall formed from a telescopic arrangement of sidewall ring members. A corrugated spacer band supports the upstream end portion of each sidewall member on the downstream end portion of the next inwardly located sidewall member in the upstream direction. An annular coolant admission slot is thus provided between the sidewall members with the corrugated spacer band located therein.The downstream end portion of each sidewall member extends as an annular lip projecting downstream from the downstream end of the corrugated band to discourage mixing of the hot internal gases with the coolant air flowing as a film through the slot and along the inner sidewall surface.

  • Low smoke combustor for land based combustion turbines
    Patent number: 4475344
    Abstract: An improved combustor basket for a land-based combustion turbine comprises a plurality of ring segments joined in telescoping fashion to form a constant diameter basket, the downstream end of each ring segment having an extended lip for improved film cooling of the interior surface of the ring segments, a combustor dome adjoining the upstream end of the combustor basket and having an interior splash plate directing a cooling air film along the interior surface of the dome wall, fuel injecting means, and oval-shaped scoops for directing the flow of compressed air into the combustion zone. Each ring segment, excluding the first, comprises an upstream cylindrical section, a conical section, and a downstream cylindrical section, which geometrical arrangement permits construction of a constant diameter combustor basket. The combined improvements of the present combustor basket result in more efficient and complete combustion, which results in the production of less smoke.
