The gas turbine 1 in this embodiment is a gas burner, which is classified as a natural gas burner, and according to its working principle, the burner can be defined as a device that converts a substance into heat energy through a chemical reaction, i.e., air and fuel are mixed in a proper ratio by a premixing device to be sufficiently combusted. The combustor burns fuel and air in a combustor flame tube according to required concentration, speed, turbulence and mixing mode to generate high-temperature and high-pressure gas which is sprayed out from a transition section of the combustor and enters a turbine of a gas turbine 1 to do work; the waste heat boiler 2 in this embodiment, as the name implies, is a boiler that heats water to a certain temperature by using the waste heat in the waste gas, waste material or waste liquid and the heat generated by the combustion of combustible substances thereof in various industrial processes, and comprises a boiler barrel, a movable smoke hood, a fire hole section flue, an inclined 1 section flue, an inclined 2 section flue and a final 1 section flue, the waste heat boiler 2 is divided into six circulation loops, each circulation loop consists of a downcomer and an upcomer, feed water of each section of flue is introduced into a lower header of each flue from a boiler barrel through the downcomer and then enters each heating surface, water generates steam after passing through the heating surface and enters an inlet header, and then is introduced into the boiler barrel through the upcomer, and all the flues are connected by flanges; in this embodiment, the steam turbine 3 is also called a steam turbine engine, and is a rotary steam power device, high-temperature and high-pressure steam passes through the fixed nozzle 305 to become an accelerated gas flow, and is then sprayed onto the blades, so that the rotor with the blade row rotates and does work outwards, and the steam turbine 3 is an external combustion rotary machine capable of converting steam heat energy into mechanical work.
