The invention discloses a nozzle of a combustion chamber of a miniature gas turbine, relates to the gas turbine technology, and in particular to a small size fluid fuel nozzle used in a combustion chamber of a 100 kW level miniature gas turbine. The nozzle consists of three parts which are a fuel oil passage, a fuel air passage and an air channel at the root of a burner, comprehensively utilizes the advantages of pneumatic nebulization and pressure atomization, and is a combined type high performance pneumatic atomizing nozzle. The nozzle of the invention has the characteristics that: the nozzle adopts a conventional processing method to realize excellent atomization of the fuel in small scale space, so as to meet the requirement for the quality of fuel atomization under a quite wide burden of the combustion chamber of the miniature gas turbine; the nozzle can avoid burnout and overcomes the defect of nozzle blockage caused by high temperature coking of the fuel; meanwhile, the nozzlecan make the fuel in the combustion chamber to be combusted more fully and reduce discharge of pollutants such as smoke black and so on.

The invention discloses a spray desuperheater, which belongs to the field of boiler plants. The spray desuperheater comprises a tubular desuperheater header and the like. An inner sleeve is sleeved to a cavity of the desuperheater header. A primary venturi tube and a secondary venturi tube are arranged in the cavity of the inner sleeve, wherein the flared section of the primary venturi tube enters the cavity at the throat of the secondary venturi tube from the left end of the secondary venturi tube. A cooling water pipe vertically runs through the desuperheater header and the inner sleeve; the lower end of the cooling water pipe is connected with an upper end at the throat of the primary venturi tube; and the cavity of the cooling water pipe is communicated with that of the primary venturi tube. The lower end of a centrifugal nozzle runs through the cooling water pipe and then is extended into the cavity of the primary venturi tube; and the spray directions of spray orifices at the lower end of the centrifugal nozzle are dead against the secondary venturi tube. Due to the combination of the centrifugal nozzle and the primary and secondary venturi tubes, the spray desuperheater solves the problem of small atomization range and poor heat exchange effect of desuperheating water, is simple to machine, and can highly-efficiently atomize the desuperheating water in large scale to further effectively improve the heat exchange performance of the desuperheater.
