Abstract

303,411. Akt.-Ges. Brown, Boveri, et Cie. Jan. 2, 1928, [Convention date]. Heating parts. - Means are provided for preheating a turbine and for keeping it hot in order that it may be put into operation quickly, when required, without it being subjected to heavy heat stresses. This is achieved by passing through it a heat carrier, such as superheated steam or air, which has been heated so that it will preheat the turbine to a temperature equal to that prevailing when the turbine is in operation. Fig. 2 shows an arrangement in which air, heated in a steam heat-exchanger 10, is passed through a pipe 11 to the first stage 5 of the turbine from which it is drawn off at a point 7, which may also be a steam tapping point, and returned by a fan 8 to the heat-exchanger. The air also serves to heat the valve gear 15, and may have access to the interior of the rotor. The heat-exchanger 10 may be heated by an oil furnace or flue gases. During preheating the turbine shaft may be turned slowly by a barring device. When the turbine is to be put into operation, the heating system is cut off by closing valves 16, 17. In a modification, flue gases from the boiler are used as the heat-carrier. Fig. 4 shows an application to a multistage turbine 25, 26, 29 in which the heated air is driven by a fan 27 throughthe first two stages in series, the final stage being left open without flow, or being kept under vacuum. The air is heated by electric heating elements 35, 36, 37, connected in series or in parallel according to the heat required. The flow of heating air through the stages may be varied and regulated. Fig. 6 shows a modification in which the air, heated by an electric device 54, is caused to circulate in the space 57 outside the turbine casing 59 after it has passed through the turbine. The electric heater may be controlled by a thermostat 60 acting through a relay device 63, 64, and a controller 65. Relay controlling devices may be employed where steam or flue gases are used as sources of heat.
