Claims

[Claims for Utility Model Registration] 1. The amount of air extracted by an air bleed pipe opened in the middle of a turbine stage group is controlled by an air bleed adjustment valve to regulate the extraction pressure, and the regulated oil is sent to the air bleed pipe. In a bleed turbine plant that supplies air to an industrial plant via a bleed pipe, a pressure detector is installed on the industrial plant side of the bleed pipe to detect the bleed pressure, and the pressure is adjusted according to the bleed pressure detected by this pressure detector on the industrial plant side. A bleed air turbine plant characterized in that the bleed air pressure is regulated by appropriately controlling the opening degree of the bleed air regulating valve, and an amount of bleed air corresponding to the amount demanded by the industrial plant is supplied to the industrial plant. 2. The bleed pipe is connected via a connecting pipe to the main steam pipe that guides the steam generated in the boiler to the high-intermediate pressure turbine, and this connecting pipe is equipped with a regulating valve that controls the steam flow rate.
Registration of a utility model in which a check valve is installed in the bleed pipe upstream from the point where it connects with the connecting pipe, and a part of the main steam generated in the boiler is supplied to the industrial plant through the bleed pipe. An extraction turbine plant according to claim 1. 3. The bleed pipe is connected via a connecting pipe to a high temperature reheat pipe that guides the steam reheated in the boiler to the high and intermediate pressure turbine, and this connecting pipe is equipped with a regulating valve that controls the steam flow rate, and the above-mentioned A check valve was installed in the bleed pipe upstream from the connection point with the connecting pipe, and a portion of the reheated steam reheated by the boiler was supplied to the industrial plant through the bleed pipe. The bleed air turbine plant according to claim 1 of the utility model registration claim. 4. The pressure detector is connected to the industrial plant side of the bleed pipe,
The bleed air turbine plant according to claim 1, which is installed in a collection header that is connected to a plurality of industrial plants and distributes bleed air to a plurality of industrial plants. 5 The main steam pipe is branched midway to bypass the high and intermediate pressure turbine.
- A high-pressure bypass pipe is connected to the middle of the low-temperature reheat pipe that returns the steam discharged from the high- and intermediate-pressure turbine to the boiler. The extraction turbine plant according to claim 2 of the utility model registration claim.
