Turbine residual heat recycling and utilizing system

Abstract

The invention discloses a turbine residual heat recycling and utilizing system which mainly comprises a residual heat boiler, a hot oil circulating pump, a smoke valve and a field control disc. High-temperature smoke discharged by a turbine motor is used as a heat source and the residual heat of smoke is recycled; heat-conducting oil is introduced to a residual heat boiler heat exchanging disc through a hot oil circulating pump and the heat-conducting oil in a residual heat boiler heat exchanging coiled pipe is heated by utilizing the high-temperature smoke; and after the heat-conducting oil is heated, the heat-conducting oil is returned to a heat-conducting oil system. According to the turbine residual heat recycling and utilizing system disclosed by the invention, the heat energy in turbine smoke can be recycled and the heat-conducting oil can be heated by effectively utilizing the residual heat of the smoke, so that the temperature of the heat-conducting oil is improved, the consumption of fuel is reduced, the load of a previous heat medium boiler is reduced, and the normal maintenance of the heat medium boiler and the normal operation of a hot oil system are guaranteed; and therefore, the risk of safely operating the previous heat medium boiler is reduced, the safety operating factor of equipment is improved and the pressure of outputting crude oil is relieved. Meanwhile, the emission of atmospheric pollutants is further reduced, and energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to a system for utilizing waste heat, in particular to a system for recovering and utilizing waste heat from turbines. Background technique [0002] A platform or floating production, storage and export system (FPSO) is generally equipped with two heat medium boilers, one for use and one for standby, so as to ensure that one of the boilers can provide heat normally when the other boiler is overhauled. Continue to meet the heating needs of the whole ship's thermal oil users. [0003] With the increase of offshore platforms, the amount of liquid that needs to be processed daily also increases, so the load of the original heat medium boiler increases greatly. In order to ensure the quality of crude oil exported, two heat medium boilers must be put into operation at the same time to increase the capacity of processing liquid. In this way, there is a lack of spare boilers, which reduces the normal maintenance opportunities of heat med...

Problems solved by technology

In order to ensure the quality of crude oil exported, two heat medium boilers must be put into operation at the same time to increase the capacity of processing liquid. In this way, there is a lack of spare boilers, which reduces the normal maintenance opportunities of heat medium boilers and increases the chance of safe operation of the boilers. risk
